Remove Rust From BBQ Grills & Smokers

Posted by Rodger Busse on

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.

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!
