Mold--tiny spores that grow in warm and damp environments--grows quickly on a variety of indoor and outdoor surfaces, including walls, floors, patio chairs and even your barbecue grill. Your grill's grate, interior walls and lava rocks or charcoal is susceptible to mould growth due to food debris left inside of the grill and the enclosed environment when the grill is not being used. Mold growth needs to be removed before using the grill. If you don't remove the mould, it will just continue to grow and spread.
Turn off the grill's propane tank, if it is a gas grill.
Use a wrench to disconnect the propane line from the gas grill. Remove the propane tank and set it to the side.
Place two trash bags underneath your grill, whether it is a gas or charcoal grill. Open the grill's lid.
Wear work gloves to protect your hands and remove the grate and any lava rocks or charcoal in the grill. Place the lava rocks in a bucket. Dispose of the charcoal in the trash.
Spray the grate, the inside and the outside of the grill with a water hose to remove any loose debris and mould.
Scrub the grill's burners with a grill brush to remove any caked-on debris and any visible mould.
Fill a bucket with 1 cup dishwashing liquid and 1/2 gallon water.
Dip the grill brush into the soapy mixture and scrub away the mould on the inside and outside of your grill.
Use a rag or cloth to scoop out any mould and debris from the inside bottom of the grill. Place the mould and debris in a trash bag.
Place the grate back inside of the grill.
Dip the grill brush in the bucket of soapy water and scrub away any mould on the grate.
Re-spray the grate, the inside and outside of the grill with a water hose to rinse away the soap, debris and mould.
Scrub the lava rocks with the grill brush. Spray them clean with water until all debris and mould is gone.
Remove the trash bags from under the grill and dispose of them.
Dry the inside and outside of the grill with a clean rag or towel.
Place the lava rocks used-side-down inside the grill. If using charcoal, place new charcoal in the grill.
Reattach the propane tank, if it is gas grill. Turn on the propane tank by opening the tank's knob only half a turn to keep from flooding the burners with too much gas.
Light the grill and let it burn for 45 minutes to an hour to burn off any remaining material that may still be present on the grill's grate and walls.
Clean your grill after each use to reduce the chance of mould growth.
