Step By Step Guide To Fixing the Grill Bottom

Let’s get into the process of removing rust from a BBQ grill.

1st Step

The initial step is to mix warm water and detergent. Then, you should apply the solution to the rusted surface of the bottom of the grill. You can use a spray bottle to apply the liquid to the surface evenly, and it must be allowed 15-20 minutes to absorb into the surface. 

2nd Step

Now, using a wire brush or sander, scrape the rust by inserting some force. Then, wash the surface off with clean water before moving on to the next step. Clean the washed surface with a piece of cloth and apply some cooking oil to it.

3rd Step

Now, to a 1:2 ratio, mix baking soda and white vinegar. Then, spray the newly made solution on the area you cleaned as mentioned in the above step and wait for a few minutes to allow the solution to absorb. In order to get rid of stains, wash the surface and wipe it off using a soft piece of cloth. 

4th Step

Then, you can use grill rust remover on the worked surface. Now the stubborn rust should be half removed or ready to get removed without much effort using the rust remover. When using these rust removers, always read the manufacturer’s manual and follow the instructions mentioned in them.

If the rust stains are not rough, you can stay away from implementing the 4th step. 

5th Step

The final step is to coat the surface with lemon or lime juice and allow the machine around 24 hours to get the most out of the juices. Once everything is done, wipe the bottom of your grill with a clean piece of cloth and store it in a place where there is no moisture.
