Why Does My Gas Grill Rust Out?

Even with the preventive measures below, rust can still form on your grill over time. But it is essential to understand why it happens to be able to avoid them from happening.

  • Water: Moisture is the main culprit for causing rust on grills. It would be best if you protected outdoor grills from wet weather and snow. And always oil your grill after cleaning with water.
  • Saltwater: Salt and humidity in the air, especially in places in the ocean, corrodes metal,  including stainless steel grills.
  • Food residue: When food particles stay on the grill for so long, they rot and become acidic,    causing rust to form on your grill surfaces.
  • Chemicals: Using concentrated bleach and cleaners containing chlorine to clean your stainless steel grill will form rust on the surfaces.

How to Fix a Rusty Grill Bottom

Usually, most grills are made of stainless steel to mean; they do not rust. However, the bottom of the grill is where all the meat juices and dirt collect, making it most prone to developing rust. Additionally, the level of damage determines the measures to restoring a barbecue grill.

When the damage isn’t too much and is reversible

A grill that isn’t too damaged has a variety of solutions. The first step to any cleaning method is to turn off and disconnect your grill from the gas cylinder. Then, disassemble the grill to expose the rusty grill bottom. Below are some of the things you can do:

Scrapping off the rust

A quick and easy solution to removing rust is using an abrasive material such as a wire brush, steel wool, or sandpaper. Be cautious when using a wire brush because it can remove the protective layer from the grill surface over continued use. First, you have to dry brush to remove the ash and charred flakes and then wipe it down with detergent and water.


  • Use a wire brush to scrape off the large lumps and dirt.
  • Use a shop vac to remove the big chunks of dirt.
  • Wet the surface using liquid dishwashing soap and scrub with steel wool or sandpaper. Pay close attention to the corners because rust attracts rust.
  • Rinse it off with clean water.
  • Wipe it down using a cleaning rag or paper towels.
  • Spray some vegetable oil.

Washing with dishwashing soap and water

For less stubborn stains and after every use, you can always rely on some dishwashing soap and water to clean a rusty grill bottom. Do not use any toxic cleaning detergent as this part is also exposed to your food. It may also corrode your grill and worsen the rust.


  • Mix some liquid dishwashing soap with water in a bucket or spray bottle.
  • Spray the surfaces of the grill bottom, soak for about 15-20 minutes to dissolve the rusting grease.
  • Scrub with a rag or nylon brush to remove any remaining rust particles.
  • Rinse and wipe it down dry.

Vinegar and baking soda

The acid in the vinegar will lift the rust while the baking soda reacts with the acid and foam, allowing the acid to go into cracks and crevices.


  • Mix some white vinegar and baking soda in the ratio 1:2 in a spray bottle.
  • Spray it generously on the surfaces and allow it to soak for a couple of minutes.
  • Use a soft bristle brush to scrub off any remaining rust stains.
  • Wipe it dry with a clean rag.


The high levels of phosphoric acid in soda, particularly Coke, lifts rust from metallic surfaces.


  • Pour a decent amount of soda in your grill bottom.
  • After 30 minutes of soaking, scrub the surface with steel wool.
  • Rinse and dry the surface…
