What Causes Your Gas Grill to Rust?

Rust may form on your grill even after you’ve taken the preventive measures outlined below. But, to prevent this from happening again in the future, you must first understand why it happens.

Water is the most prevalent source of rust on grills: It would be ideal if outdoor barbecues could be protected from severe weather and winter snow. Additionally, always oil your grill after washing it with water.

Food residue: At the time food particle stays on the grill for a lengthy amount of time, it degrades and become acidic, forming rust on the grill shells.

Saltwater: It corrodes metals, especially stainless steel grills and barbecues, due to the mix of salt and humidity in the air, particularly in coastal locations.

Chemicals: Cleaning your stainless steel grill using concentrated bleach or chlorine-containing cleaners may result in the formation of rust on the surfaces.

Rust removal using a scraper

To remove rust quickly and easily, use rough material, for example, a wire brush, sandpaper, or steel wool. First, dry brush the surface to remove any ash or burned flakes. Then, clean it with a light soap and water solution.


  • Using a wire brush, scrape away large chunks of dirt and debris.
  • Use a shop vac to remove huge clumps of dirt from the area.
  • Make the surface wet with liquid dishwashing soap and scrape away any leftover debris using sandpaper or steel wool. Because rust attracts extra rust, pay special attention to the corners.
  • Rinse it sound with fresh water to remove it.
  • Wipe it down with paper towels or cleaning cloths.
  • Vegetable oil applies with a thin layer.

Cleaning dishes with dish soap and water.

You can always clean a rusty barbeque bottom with dishwashing soap and water. If the stains are not too stubborn or utilize the grill after each use. Avoid using harsh cleaning agents in this home area since they will come into touch with your meals. 


  • Combine water and a few liquid dishwashing soaps in a spray bottle or bucket to create a solution.
  • Then soak for about 15-20 minutes to thoroughly dissolve the rusting oil on the grill’s bottom surfaces.
  • Using a nylon brush or cloth, remove any residual rust particles to ensure they are entirely eliminated.
  • Rinse it well and make it dry with a dry towel.

Baking soda and Vinegar both are good household cleaners.

Rust may be removed using the acid into Vinegar, while baking soda reacts with the acid and forms foam. Allowing the acid to enter cracks and crevices more readily.


  • Combine equal parts baking soda and white vinegar in a spray bottle (in a 1:2 ratio).
  • Apply a thick layer to the surfaces and leave to soak for a few minutes before wiping clean.
  • Scrub any sort of remaining rust tints thoroughly with a soft bristle brush.
  • To remove any residual moisture, wipe it down with a clean cloth.


In particular, it has a high concentration of phosphoric acid, which is very efficient in removing rust from metallic surfaces.


  • Fill the bottom of your grill halfway with Coke.
  • After 30 minutes, use steel wool to remove any leftover residue.
  • Wipe the area clean with a clean cloth and let it dry.

Commercial rust remover

Commercial rust removers formulated specifically for kitchenware are available. Buy a non-toxic rust remover that effectively removes rust from surfaces that come into direct contact with food. 


  • Cleanse the grill bottom with a brush to remove any oil or dirt.
  • Allow the rust remover to soak on the surface for the period provided in the package directions.
  • Use a clean, wet cloth to remove the substance from the surface.

Citric acid is a specific kind of acid.

Citrus fruits, for example, limes and lemons, contain citric acid, which may be substituted for Vinegar. With the help of mild acid, rough metal surfaces may be readily removed. This may be used with dishwashing soap, salt, or baking soda. 


Prepare enough citric acid mixture to create a thick paste and coat the bottom of the grill pan thoroughly with it.

  • Allow sitting overnight to discharge the rust particles.
  • To remove any leftover rust spots, steel wool should be utilized.
  • Rinse the dish and repeat the operation if necessary.

When the destruction is substantial and necessitates the replacement or repair of the bottom

Due to repeated use or neglect, rust on the grill bottom may have caused significant damage, demanding a replacement or repair.

Examine the grill’s bottom for fractures or holes and assess the extent of the damage. While small holes can usually be rebuilt, larger holes may need the replacement of the entire bottom. 

How to Keep Your Grill from Rusting Abruptly

Preventing your grill from rusting early by adhering to a maintenance schedule. Remove any little amount of rust as quickly as possible to prevent it from spreading.

Stainless steel grill with ceramic grates

While stainless steel is not totally corrosion-resistant, it is very corrosion-resistant. Which permits it to retard the rusting process. Along with being non-stick, ceramic-coated grates prevent water from coming into direct contact with the grill’s other metallic components. Over time, heat and repeated washing will degrade the protective layer.

Clean the area carefully after each use

After each use, properly clean the grill. It is vital to keep the grate clean and all the other components clean to prevent rust by speeding the oxidation process. Food particles left on metallic surfaces speed up the rusting process.

We recommend deep cleaning regularly.

Deep cleaning your grill may help prevent the collection of dirt and corrosion in seldom-cleaned places. Dismantle your grill completely and clean all the grill’s internal components using one of the processes outlined above.

Toss your grill

Post cleaning your grill, cover both the inner and exterior surfaces with a min vegetable oil layer. The oil stops water from coming into contact with the metallic surfaces, preventing corrosion.
