Grill elements can get damaged over time. Replacing certain parts and giving the grill a good cleaning will prepare it for the season to come.
Step 1: Turn off the propane.
First, be sure the propane tank is turned off. The propane tank should always be turned off when the grill is not in use.
Make sure the propane is off.
Step 2: Remove the old grill and flavorizer bars.
Remove the old grill and flavorizer bars from their places in the grill. Some grills use lava rocks to disperse the heat. If this is the case, remove them. If these parts are starting to rust, it is a good idea to buy replacements.
Remove the grill and bars.
Step 3: Scrape and vacuum the inside.
Use a shop vacuum to clean out the inside of the grill. Use a paint scraper to scrape off the baked-on food, and vacuum it away. Continue until the sides and bottom are clean. You may want to use steel wool and some hot, soapy water to give the inside a thorough cleaning.
Vacuum the inside of the grill.
Step 4: Brush off the burners.
Using a brass wire brush, clean all the burners to ensure consistent cooking. Brush over all the holes of the front, sides and back burners to remove rust and scale. Brass wire will not leave bits of steel behind, which rust over time.
