Well, there are far more devastating things happening in the world, however, in the BBQ world grill mold is pretty bad.
Grill mold does not discriminate, it doesn’t care if you have a charcoal grill, a pellet smoker, or a custom rig. If there is a nice moist spot, it will invite itself over.
So then, what is the best way to kill mold? Do you just throw away the grill? Put the cover back on and hope it will go away? Sadly none of these options are going to cut it.
Before we decide what to do in this situation, we need to find out how we got ourselves into this moldy situation.
Let’s jump into mold and everything you need to know about how you get mold, how you prevent mold and what is mold.
So, What Exactly is Grill Mould?
Mold is a term used for fungi that grow in the form of a multi cellular almost thread-like structure.
Mold is found in damp areas which have poor ventilation and/or high humidity levels.
There are lots and lots of different types of mold. Mold comes in different colors, textures and smells. Some can cause disease and can be very harmful to the human body.
Charlies Hot Tip
If you can smell mold, it is wise to get rid of your barbecue or smoker cover and continue with the cleaning steps below.
Preventing Mold (Like They Say Prevention is Better Than A Cure)
One of the best ways to prevent mold is to super heat your cooker after you have finished cooking.
Step 1: Super heat your BBQ or smoker. If you need to add fresh coals to get the temperature back up do it! It will save you in the long run. You want to get a good high temperature back, then burn off all the food residue that has built up throughout the cook.
Step 2: Once all the food residue has been burnt off, its time to work on the interior. With a plastic putty knife, you want to scrape away any grease build-up, food and excess charcoal. This can be a breeding ground for mold.
Step 3: After everything is cleaned you want to dry the interior as much as possible and pop the cover on. Make sure before you put the cover on that you open all vents or take away any side piece that can expose the interior, this will allow any additional moisture to escape.
Another major cause of mold is your cover. It traps moisture and creates the perfect conditions for mold and rust.
Try and avoid using a cover/lid if you can, your pride and joy will not fall to pieces! If you can store it in the shed or under a covered area.

Take away any charcoal, ceramic briquettes, lava rocks or other porous materials from the grill.
- Fire up the grill! Make sure it is as hot as possible, this will kill the mold and burn off the mold and any grease that has built up. Use a decent amount of fuel for the fire, you want to get as much burnt off as possible. Do not try to scrape or power wash the mold off. You might inhale spores and could possibly have a reaction. You could also spread the mold.
- After the fire has burnt down, let it cool and then scrub and scrape everything you can get your hands on! For best results use a pressure washer or a wire brush. If you don’t have a pressure washer you are going to need a lot of elbow grease.
- Once everything has been scraped off, give everything a good wash down with hot soapy water. Making sure to give everything a good rinse down afterwards.
- Finally, fire up the BBQ one more time. This will ensure that any soap residue, moisture, grease and mold has been totally eradicated.

- Get half a meter of aluminum foil, scrunch it into a ball
- Rub the foil all over the grill and wipe away any remaining grease and food debris.
- Repeat the process as needed
