As the lazy days of summer wind down, it may be time to take a close look at your gutters before fall sets in and the rains start in earnest. Take a close look to check for rusting metal.   The thing you will want to avoid at all costs is having rust break through. If this happens, you may be looking at an expensive replacement. You also want to keep your gutters in good repair to keep water from getting close to your foundation or on the siding,  causing expensive damage.

Wow! Water clean up on the job!

YIKES! Rusty metal break through!

Tips for Removing Rust

  • Make sure you are comfortable being on a ladder. Never a good idea to work alone on a ladder or roof when someone is not home with you – in case of a fall.
  • Wear protective eye guards to keep debris such as dirt and leaves out of your eyes. A hard hat is a good idea when on a ladder or roof.
  • Start by clearing the gutter of all dirt and debris. Leaves, dirt and needles really pile up over a season.
  • Use a wire brush knock off loose flakes of rust and paint. There is no need to sand down to the bare metal. Rust Doctor needs rust in order to convert it to a hard surface of magnetite for long term protection.

  • Wash the gutters with a product like Grease Doctor. This is a concentrate that can be diluted as a cleaner or degreaser.  You may want to spray Grease Doctor with a spray bottle or some customers prefer a garden sprayer.
  • Rinse thoroughly. Sponge out the excess water so there are no puddles of water.  It is OK if the surface is damp.
  • Apply Rust Doctor to the rusty metal. You can apply Rust Doctor over the whole prepared surface. When the rusted metal converts, it will be black with a clear primer on the top, ready for paint. You may want to consult a paint store professional on the best type of paint to use on your Rust Doctor treated  gutters.

Renewing Old Playground Equipment & Remove Rust

It’s Fun to Be a Kid

It’s great to see children play on outdoor equipment. It helps to develop their muscles, coordination and social skills. Check out the  research on the benefits of outdoor play here.

Kids love to climb, slide, ride, spin, shoot baskets and swing at home and in neighborhood parks and schools. However, if the play equipment is old and in need of repair, it could be a safety hazard and it just looks run down.  Playground equipment for the most part is designed for extreme  weather conditions, but over time elements like water, the sun and wind takes a toll on metal. You can restore and bring to life on your own backyard or neighborhood playground is made easy with the Rust Doctor products. Outdoor equipment is expensive to replace. With Rust Doctor, you can remove the rust with ease and make your outdoor playgrounds look new again.

Kids playing

Virtually all standard paints require the removal of rust before surfaces can be primed and painted. With Rust Doctor, rust does not need to be removed. Rusty surfaces only need to be cleaned before they are treated with Rust Doctor. This saves a great deal of time and effort in the repair and maintenance of metal surfaces. In addition, Rust Doctor incorporates a clear latex primer that dries on the surface, allowing for the application of a topcoat. The Rust Doctor converts the rust and primes the surface, all in one easy step. Rust Doctor products are safe to use – non-toxic, non-flammable, and biodegradable. There is no need for respirators and other safety measures that are required with solvent based products. Water clean up makes this job easy.

Steps to Remove Rust from Playground Equipment

1. Prepare the Rusty Metal for Treatment
Using Rust Doctor is very easy. Clean the rusty surface with a wire brush to remove any loose rust and paint flakes.  On large surfaces this can be done with high-pressure washing. Clean the surface to remove any surface contaminants such as dirt, grease, and oil . Use a water-based degreaser such as the Grease Doctor. (If you are pressure washing, add the degreaser to the pressure washing water. Rinse thoroughly with water. If a water source is not near by, use a bucket with water and wipe it down. Here are some extra tips for preparing to paint your playground equipment.

2. Apply Rust Doctor to the Rusty Metal
Be sure surface is dry. Apply Rust Doctor with brush or spray system. On some surfaces, such as the rungs on your jungle gyms, you can use paint mitts. These paint mittens are available at your paint stores and home improvement centers.  These mitts have a plastic lining to protect your hands from getting pain all over them.  Apply enough Rust Doctor to cover the rust completely. Do not allow any rust to show through the surface. If necessary, apply a second coat of Rust Doctor while the first coat is still tacky or after 24 hours.  In a few minutes, Rust Doctor begins to convert the rust, turning it black.


Helps to keep paint off your hands

The conversion process turns the rust black as it changes to magnetite – a very hard form of iron oxide. This hard surface protects the metal from future rusting and is not affected by moisture or oxygen. After the conversion process is complete (in 16 to 24 hours), the surface has turned completely black and has a slight sheen. This sheen is the result of the latex primer that remains on the surface. The primer creates an excellent base for any kind of kind of topcoat.

3.  Obtaining a Smooth Surface
There are various ways to obtain a smooth surface when using Rust Doctor. You can sand the rust to a smooth surface (it is not necessary to sand to bare metal). If, after applying the first coat of Rust Doctor, it still is not as smooth as you would like, a second coat can be added to achieve a smoother surface. Another and perhaps easier method is to use sanding primer on the metal after the Rust Doctor has dried. Sanding primer is a fast drying paint that fills and smooths surfaces effectively. Because it dries quickly, successive coats can be added in a short period of time. Sanding between coats helps to smooth out the surface.

When you have achieved a surface that is as smooth as you desire, you can top coat with any type of paint. Specifically, Rust Doctor will accept enamel, alkyd, oil, vinyl, latex, epoxy, urethane and lacquer topcoats. You can also weld on surfaces treated with Rust Doctor.  It’s always a good idea to save the leftover paint to touch up any future nicks or scratches.
What could be more fun that choosing some great colors for a children’s playground?

Remove Rust All Around the House

Not all rust removal projects are large and take months or even years to complete. Some projects are just not worth the time and work it takes to remove rust. In other words, they are ready to R.I.P.

ships of the desert


But as you look around your home, you may see that some of your possessions or collections may need some rust removal and a little sprucing up.  Take the yard and garage as an example.  Sometimes it seems like rust has grown overnight on your garden bench and wheel barrel. As metal is exposed to the elements, it makes for a friendly environment for rust to develop. Rust Doctor makes this job easier.

wheel barrel

This could be anybody’s wheel barrel


Factory items made from metal need to be protected right away in the factory. What you can’t see is the rust developing in the pores of the metal if a protective coating is not applied. The amount of time for the product to rust depends on moisture and humidity in the air. This rusting process can start from a few hours to perhaps 24 hours.  While the paint may look all shiny and new, it is only a matter of time before the rust breaks through.  An example might be a wheel barrel.  A wheel barrel is made to “work”. You will haul dirt, sand, rocks etc in it. How about mixing cement in your wheel barrel? It doesn’t take much time and that rusty metal is coming through, especially when the paint gets scratched and nicked.  Of course it is human nature to let it go sometime before you tackle a re-do on your wheel barrel to remove rust.  But if you let is go long enough, your wheel barrel will develop holes in it and eventually become useless. But you can remove rust before it gets to that breaking point with the Rust Doctor and have your wheel barrel hauling materials once again.

Remove Rust from Your Outdoor Furniture

There are many wonderful styles of outdoor furniture. There are the very ornate cast iron chairs, gliders, benches and tables.  Retro-style tables and chairs have made it back into porches and yards.  While there are some companies that are trying to copy the old style, you can beat the sturdy quality of the truly old metal pieces.  We researched some of the history on this style of furniture, and some of the gliders we discovered were made in the 1920’s. Some companies specialize in the restoration of old metal furniture. A single restored chair can sell for $275 while an old style glider can fetch close to $2,000. Unless you want to part with a lot of money, you may want to restore these beauties yourself. There is a real satisfaction if completing a project where you do the rust removal and painting yourself.

Remove Rust from Postal Mail Boxes

If you look high and low, you can see where rust removal will  preserve  old treasures.  There are many charming old postal boxes in mostly older homes and buildings that have rusted.  When rust is allowed to progress, you can loose the detail in the mail boxes. This is why it is important to remove rust early on.  We happen to have the newer version and very common style of mail box that sits out by the curb. It is amazing how quickly it can rust. The amount of road dirt and grime that gets sprayed on the row of boxes is amazing. But removing rust from a mailbox is a week-end project you can accomplish.  Removing a box and installing a new one is more difficult than rust removal. Whether you are restoring or replacing a mailbox, check here to the USPS guidelines for installing a mail box.

A classic


Who hasn’t gone down a street or boulevard and noticed city poles and street signs that are covered in rust? You may not be able to have a say in the maintenance of these poles or street lamppost, but you can control what you have on your property. You can keep them fresh and sharp looking with little effort with Rust Doctor products.



Weather-vanes seem to really take the brunt of the weather elements. Many historical weather-vanes eventually will rust through and loose the ability to work or may fall apart all together. It would be a shame to loose these old treasures. There is no reason to not save these beauties with a little time and effort in a couple of days. Remember – safety first. Check out this web site for 10 safety tips if you are going up on a roof to work on a weather-vane.


Remove Rust from Old Tool Boxes

Some folks say you can’t trust a home baker who has a shiny new looking cookie sheet.  You could almost apply that saying to a tool box. Unless you have a brand new tool box, more than likely the tool box will get beat up over the years and start to rust. What a great surprise for the “do-it-yourselfer” if you could restore that old tool box for someone.  There are some great vintage boxes out there that are sturdy and solid and have many years left in them Consider gifting a restoration of a old  tool box for  a good friend or a family member who values their tool box and would appreciate an updated look. Perhaps you could add a special look to the box. Maybe pin striping, flame job, or their initials?

Remove Rust from Metal Casement Windows

Restored window casement

Example of a beautifully restored metal encased window

Many older buildings that have metal encased windows. You will often see these types of windows in older homes, apartments and commercial buildings. Often these window encasements add a beautiful architectural look to the building. Being metal, they are exposed to the elements and over time can rust. Replacing this type of window is costly, and can be inconvenient in an occupied building. Rust Doctor has a solution for those rusty window encasements.

Oxidation on iron and steel is easy to spot. It is identified by its reddish brown color and its tendency to powder or flake off. Rust creates hard bubbles under paint, which forces the paint from the surface, exposing the metal. This process of exposing the metal causes the metal to rust even faster. The breaks down until it crumbles and flakes. If there is rust on your window encasement, it is best to deal with it as soon as you can.

rusted window casement

This window encasement is ready for a repair job with Rust Doctor


The first step is to clean off as much of the loose rust. Start by brushing with a wire brush along the surface of the metal framework. This will not hurt the good steel underneath the old paint, but will remove loose flakes of old paint and rust. Remove pieces of paint and rust that have started to flake away from the surface of the metal.  This will give you a smoother surface to repaint. You can try a power washer instead of using a wire brush, but be sure if takes off the rust and the paint flakes. Check out our video on using Rust Doctor.


Wash down the casements with a water-based product like Grease Doctor cleaner/degreaser to remove any dirt or accumulated contamination that may be present. Rinse thoroughly with water. If you are restoring your windows on the inside, you will need to use a bucket and a rag to rinse off the cleaner.


After the window encasements are dry, you are ready to paint Rust Doctor on the rusted and painted surfaces. Rust Doctor is dry to touch in 30 minutes and ready to paint after it has cured for 24 hours.  The surface will turn the rusty metal black and have a clear primer.  You can choose to leave the window encasement black, or use another color of your choice. We would recommend you consult with your local paint store for the best type of paint for your encasement windows. Rust doctor can be top coated with all types of paint, both latex and solvent or oil based paints.

Rust Doctor is non-toxic, non-flammable,e and biodegradable. This makes Rust Doctor very attractive for those inside jobs. Many rust paints are solvent based and requires special respirators  and ventilation when using their products. Rust Doctor is water based…which means water clean up for the consumer.

Rust Removal from Metal Railings, Gates and Fencing


rust railing

Don’t let your fencing get to this point.


We often get  inquiries about rust removal on metal rails, fences and gates.  New metal railings, fences and gates can be costly.  Some customers have fairly new metal fences and are surprised at the amount of rust that sometimes develops in 6 months or less.   This happened to a Rust Doctor team member with a gate they purchased this summer. Rust had developed in a short time. In this case, the rust started where the upright and cross piece met and was welded together.

It’s important that when you are ready to re-furbish your fences and rails, that you take to steps to remove rust permanently.  Here are the steps for success for rust removal.

  • Clean off the loose rust and paint with a wire brush. If the rust is fairly new, you may be able to use a power washer to loosen up the flakes of rust and paint.
  • Use a cleaner/degreaser like the Grease Doctor. You want to be sure the surface is free of dirt and any oil and grime that may be present. Thoroughly rinse the surface with water.
  • Once dry, apply the Rust Doctor. A trick  to make painting the rails and decorative surfaces easier is to use a painter’s mitt. Painting intricate pickets or rails can be difficult, so using the mitt makes the job go faster. The rusted areas will turn black.  It is best to apply the Rust Doctor to the whole surface of the project. When Rust Doctor is applied, it also leaves a clear primer on the surface. You can decide to leave it black, or paint the surface with any paint type or color.

Be sure you get the paint mitts for this type of job

  • Wait 24 hours for the Rust Doctor to dry or cure. Rust Doctor is dry to touch in 30 minutes, but not ready to paint until 24 hours.
  • If you choose light colored latex paint, such as white, you will need to use a stain blocking primer. This will prevent any tannin staining. This only applies when using a latex paint on the surface. You can skip this step if using an other types of paint or a dark colored latex paint.
  • You can weld on a surface that has been treated with Rust Doctor if the entire treated surface is rusty.
  • Be sure to figure out how much Rust Doctor you will need before ordering. A quart will cover 50 square feet and a gallon will cover 200 square feet, only requiring a single coat of coverage. If you need help figuring out how much Rust Doctor will be needed, please contact us. We also have 5 gallon buckets for those large jobs.
  • Step back and enjoy the great job you have completed. Now you will have a rust protected surface that looks great and will last a long time.

Remove Rust From BBQ Grills & Smokers

As weather warms up, we get calls and emails about how to remove rust from BBQ grills and smokers. We can almost smell the wonderful aromas as the grilling and smokin’ begins.It’s always nice to start the BBQ season with clean, good looking equipment. There is no need for your BBQ and tank to join the “rust bone-yard”! You can remove the rust with out fear of toxic or flammable applications.

BBQ rusted

You can remove rust from this Trager brand smoker.

propane tank

Don’t forget your propane tank.

You can use Rust Doctor on your grills and smokers without any problem. After you wire brush the loose rust, we suggest you use Grease Doctor degreaser/cleaner to prep the rusty metal. With the Grease Doctor, you dilute it depending on the level of grease, dirt or oily grime on the surface.  Suggested dilutions are on the label. Rinse thoroughly with water. Once dried, you are ready to remove the rust – permanently. Paint the surfaces with the Rust Doctor. It will be dry to touch in 30 minutes.  Once the Rust Doctor starts to work, you will see the rust converting to a black iron oxide. The rust that is converted to a black iron oxide is not affected by heat; in fact you can weld on the black iron oxide. When you apply Rust Doctor, there is a layer of clear primer. The clear latex primer can withstand temperatures up to 300 degrees at which point the primer will burn off (just light smoke  and non toxic).  After you have treated your grill with Rust Doctor and it has cured for 24 – 48 hours (don’t use the grill while it cures), you can fire up the grill and the spots above 300 degrees will burn off the primer coating.  The converted rust (black iron oxide) will be unaffected and will not rust. After COMPLETELY cooled, we recommend that you  use a high temp paint that is designed for surfaces like your BBQ’s and smokers. One of the great bonuses of using Rust Doctor to remove rust is the water clean up. Rust Doctor is  non-toxic, non-flammable, and biodegradable. If you have left over Rust Doctor, consider other uses on this page from our web site.

And be kind to your propane tank if you are using propane for cooking. It is a given when grilling, the crowd gathers around the grill – each offering their own tips and tricks for the grill and smoker. Happy Grilling ya’all!

Using Rust Doctor Products for Rust Removal on 1951 John Deere Tractor

Copy of tractor

Rust removal was made easy with Rust Doctor products. Here is Martin and his refurbished 1951 John Deere tractor.

Behind every restoration is a story. This story is about Rust Doctor customer Martin and his love affair with a 1951 John Deere Tractor “Johnny Popper”. Martin worked for a farmer as a young teen out in Montana helping to feed and care for 300 range cattle. In the early years on the farm, and until 1951 they used teams of horses to get the work done. A few years after WW II ended, the owner of the farm was finally able to buy a 1951 John Deere 2-cylinder tractor. At the time this was a very big deal and the local farmers from all over the region came to take a look at a machine that would make life easier. As Martin shared with the Rust Doctor, the first job of the ’51 was to work in -30 degree weather to take hay out to the cattle. Having a this John Deere tractor made this chore much easier, according to Martin.

Martin got a “call to action” during the Korean War. After serving four years in the Navy, Martin worked at several careers, including time with the railroad, Ford Motor Company, and happily settled in working for John Deere. Martin eventually headed west to California and is now retired. But he always wondered what happened to that ’51 tractor. Ten years ago Martin visited the old farm where he first encountered that wonderful machine. There it sat, in a field, old, tired, dirty and in desperate not of rust removal. Three years after that visit, the family that owned the farm asked Martin if he would like to have the broken down old rusty tractor. Martin jumped at the chance, brought it home and started the process of rust removal. Martin worked hard to restore it to its former glory using our Rust Doctor products, Rust Doctor and Grease Doctor. In a recent letter to the Rust Doctor team he stated, “The Rust Doctor products were the best way to go for this project with all of the rust removal that was needed.” Martin has recently converted the tractor to supports two riders. Now he and his lovely wife participate in many parades and events together. It’s great to see Martin reunited with his friend of 62 year – “Johnny Popper”. Yes, it was a story to be told. Thanks Martin for being such a loyal customer of Rust Doctor!

We know there are a lot of tractor enthusiast out there. If you have a special story or pictures you would like to share, please contact the Rust Doctor team.  We like to hear how you used our rust remover for your projects – whatever they are.

Repair Rust on a Heating Oil Tank

I’m wondering if the combo of Grease Doctor and a couple of coats of the Rust Doctor would be appropriate for my heating oil tank which is getting quite rusty on the lower half (the tank is located inside my basement). The tank will be hard to access on the back (wall) side. Might I be able to apply the product with a mini-roller (and long handle)?



Hi Ian,

Rust Doctor and Grease Doctor will work well for you in stopping the rust and protecting the tank from future rust. You will need to clean the tank with Grease Doctor and rinse with water. Remove and loose rust or paint on the surface the best you can. A good way to do this is to apply Grease Doctor to the surface then brush the surface with a wire brush or a Scotch Brite Pad (sold in paint stores). Rinse the surface with water. Grease, dirt, oil, loose paint and rust will all be washed off with the rinse water. If you don’t have a drain in the basement for the rinse water, use a bucket and towels to rinse the tank. You can apply Rust Doctor to the rusty metal by any method that will work for you, including putting it in a garden sprayer to reach into difficult areas. If some Rust Doctor runs onto the floor, just wipe it up with a wet rag. Because Rust Doctor and Grease Doctor are water based, you will not be dealing with strong fumes or toxic chemicals. If you have more questions or need technical help about rust removal, please contact us.

We have more “tips & tricks” on our web site that might be useful for your project. You can also check out our video on how to use Rust Doctor on your rusty metal.

Remove Rust from Rusty Nuts & Bolts

Rusted Bolts


I have ordered Rust Doctor and have a question regarding the application of the product. I intend to use it on these bolts that have been previously painted. Should I clean the bolts first… or just apply your product, and then repaint them with a rust inhibiting paint?


Thanks for your question and picture David. The picture helps us see what rust repair job you are working on and how we can answer question about rust repair.

We suggest you clean the nuts and bolts with a small brush using the Grease Doctor cleaner/degreaser. Be sure if you see any other scratches or nicks in the area of your rusty metal to treat it as well. You might consider treating the whole metal plate to repair the rust. Just apply the Grease Doctor cleaner/degreaser to the area to be treated to remove loose rust and paint, and then rinse the surface with water. You need to remove loose paint to expose the rust underneath. The Grease Doctor will dissolve any contamination that might be on the surface. After rinsing the treated area, let the area dry before applying Rust Doctor. Rust Doctor treated surfaces can be handled 30 minutes after application but the treated area must be cured for 24 hours. The Rust Doctor is then ready for paint or other types of coatings on the surface.  Please contact us if you have more question on using Rust Doctor or Grease Doctor.

Pot-Belly Stove Project

We get all sorts of interesting questions about the use of Rust Doctor. Here is one from Dan who is restoring a good old fashioned pot-belly stove. Cold weather sometimes inspires us.

I purchased some Rust Doctor for a project and was very happy with the results. I now have some left over Rust Doctor converter/ primer and would like to use it on an old pot-belly stove. Your ad says Rust Doctor is non-flammable, will it work for this job? Thanks…Dan

Hi Dan,

Rust Doctor leaves two components on the surface when you treat rust. The black iron oxide which is the converted rust is not affected by heat. In fact, you can weld on a Rust Doctor treated surface. The second component is the clear primer that is left on the surface after the Rust Doctor has cured. This clear primer can handle up to 300 degrees and then begins to burn off-just smoke, which is non-toxic.

Based on this information, you can see how you could use Rust Doctor on the rusty pot-belly stove. After  Rust Doctor has cured on the stove for 24 hours, fire up the stove and let the primer burn off on the 300 degree plus areas. You could then paint the stove with a high temperature barbecue type paint. The paint will stick in the areas where the primer burned off because these paints do not need primer. It will stick on the areas with primer as well. Check out our post for other uses of Rust Doctor products.

We know the Rust Doctor will help with the rust removal on your pot-belly stove. Good luck Dan on another project!
