Remove Rust from Walk-in Coolers & Freezers

 Since we have had several customers call to order Rust Doctor to remove rust from their commercial coolers or freezers, we thought we would blog on the process of removing rust.  Rust happens  when there is condensation in the cooler or freezer. Moisture collects and unless there is a protective coating, rust will start to show up. These commercial coolers/ freezers can be expensive to replace, so good maintenance is a must to keep it in great working shape. Rust Doctor is non-toxic, non-flammable and biodegradable. This makes refurbishing the inside of a large cooler or freezer much more pleasant and easier to restore.  Unlike Rust Doctor, solvent based rust removers require special respirators and ventilation.

If the rust is on the outside of these units, it makes you your kitchen look old and not as clean and sanitary as you would like it to appear . We are featuring a picture of a small commercial freezer that has rusted and is about to take on a new life.  In this case the owner is converting it for his hobby of making home brew. The process for restoration is the same, whether you are restoring a small ice chest or a large commercial cooler.  As plastic takes over the smaller home ice chests, it might be fun to restore an old metal ice chest for your summer picnics and outings.

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.

Prepare the rusty metal for treatment
Using Rust Doctor is very easy. Clean the rusty surface to remove any loose rust and paint flakes. This can be done with a wire brush. 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/cleaner such as the Grease Doctor. (If you are pressure washing, add the degreaser/cleaner 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.

Apply Rust Doctor to the rusty metal
Be sure surface is dry. Apply Rust Doctor with brush or spray system. 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.

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.

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. It is best to talk to a professional at your local paint store for a recommendation for the surfaces you will be painting. You can also weld on surfaces treated with Rust Doctor.

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.

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.

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.

RUST REMOVAL

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.

CLEANING THE RUSTY WINDOW FRAMES

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.

PAINTING WITH RUST DOCTOR

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.

Rusty Metal Pipes & Industrial Use

Here is a good question from a company that supplies industrial pipe to companies and utilities.

A Pipe Yard 1

Good day, I have a few questions about your product, Rust Doctor. We are trying to come up with an idea for reclaiming pipe that has become too rusty for our customers requirements.

1. If we were to apply Rust Doctor to pipe that still has a partial coating would it only react  to the rusty metal  or would it peel up the coating that is still on pipe?

2. What, if any,  reaction would Rust Doctor have say to a rubber gasket, after dry of course…Your input would be helpful. Tony

Answer for those rusting pipe.

Rust Doctor only reacts with rust so it would not have an effect on any existing coating or  rubber gaskets. The basic process is to convert the rust to a non-rusting black iron oxide and leave a clear latex primer on the surface, including the existing coating. You will need to clean the surface with a water based cleaner such as our Grease Doctor cleaner/degreaser which is also safe to use on the pipe and existing coating and rubber gaskets. This should fix the rust on your pipe inventory to sell to your customers. The Rust Doctor has been used in many industrial applications for rust repair, including rusty large tanks, the marine industry,rusty beams in warehouses, rusting metal roofs etc. If you have more questions about the Rust Doctor or Grease Doctor, please contact us.

Remove Rust from Rusty Nuts & Bolts

Rusted Bolts

WE GET E-MAIL !

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?

David

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.
