1 – Check for rust
Rust happens when moisture gets trapped inside the BBQ and the metal oxidizes, turns brown, and then starts to flake. Rust is a BBQ killer and very bad for you. Most of the time rust happens on the bottom of the BBQ grill and where the gas lines enter the grill.
To check for rust, remove all briquettes, lava rocks, debris, and any other flame buffers (deflector plates, etc) from the bottom of the BBQ. If you can easily remove any burners, do that also. Use a metal paint scraper to really clean the bottom. Remove debris and look for brown flaking.
Rust can be dangerous if burned. If there’s a great deal of flaking or it is very muddy on the bottom, it may be time for a new BBQ. If there is little or no rust on the parts you can re-use them. But if they are very rusty, you can easily replace the burners, deflector plates. If they are all ok, put back whatever you took out. I recommend replacing lava rocks every 2 or 3 years no matter how they look. Re-connect the gas and go to Step 2.
2 – Check to see if the grill starts and run for 5 minutes on high
After your gas is reconnected, turn all burners on high using the electric starter and let it run for 5 full minutes. This is an important test because sometimes BBQ’s start and then stop. If it lights and stays on, skip to Step 3. If the flame goes out, make sure there is gas in the tank, wait 2 minutes and try again. Once again, if it works, skip to Step 3. If it doesn’t light and you hear the gas hissing, turn off the gas. Wait a few minutes and try again.
If it still doesn’t light, wait 2 minutes and carefully try to start it with a long match or long gas lighter. If this works, your starter might need to be replaced. If it doesn’t start, do not try it again, turn off the gas and disconnect it.
3 – Clean your grates well
When your BBQ is working, it’s very important to start your barbequing season with clean grill grates. The best way I found to do this is actually flip your grates upside down and heat on high for 7-10 minutes and scrape the bottom with a grate brush.
Then VERY CAREFULLY, using a grate lifting tool or tongs, turn the grates right side up and scrub them with the grate brush. This should get them clean.
If not, place a sheet of tin foil on the grates with the BBQ on high for 5-10 more minutes. Carefully lift off the foil and scrape whatever is left on the grates. Then, crumple up the same tin foil in a ball, and scrub the grates with the tin foil ball using tongs.
A degreaser is great for cleaning the outside of the BBQ, not the inside. Do not use it nor an oven cleaner on the inside of a BBQ ever.
It is not hard to clean and maintain your grill, and it will extend its life. It will also perform better after following these simple steps. So keep your BBQ working great!
