Mold can form on grills for a variety of reasons. The most common is building up food residue, which may go unnoticed until it has reached the point where mold growth has occurred. Mold will grow in any moist area and might not be visible at first. This accumulation of bacteria can result in respiratory irritation or infection if inhaled by humans, as well as other potential health problems to those who come into contact with it. What causes mold on grills? To avoid this buildup of mold on your grill, you should regularly clean out the excess grease from inside the grill after each use and scrub down the outside every few weeks using a mild detergent mixed with water–this will stop any buildup that could lead to an infestation of mold over time.
Why Does My Grill Get Moldy?
What causes mold on grills? Why does my grill get moldy? The answer to this question is not easy because there are several causes. [In your case it was a combination of improper cleaning and leaving the grill exposed to wet weather. Your grill can become moldy for many reasons; some more common than others. I will outline what you should be looking for in each one so that you can identify which cause is yours.
Leaving the grill exposed to moisture, either by accident or on purpose (for example, keeping it under an overhang)
The interior of your BBQ may contain wood parts that serve as storage space for propane gas tanks. These vents typically sit directly behind any cast iron grates on the cooking surface and they allow oxygen and propane to mix inside the grill. If these vents sit directly above grills and drip pans, they can cause water damage by corroding or rusting parts of your barbecue. This will not only affect how well it works but also how much you pay for repairs down the road (if any). The same goes if you find that rain is leaking into your grill through its vent holes or flame tamers (those metal screens beside your burner tubes – usually stainless steel).
I’ve seen those too! Also another thing that occurs sometimes and I’m not sure why: When coal sits in a bbq (especially when it has been “snuffed” flat) after time, the coal will turn white. I think this happens because all the coal has burned away, leaving nothing but calcium carbonate which is a major component of limestone, so I suppose when all the other components are gone it is just left in the bbq. It will not catch on fire or anything like that, until you add more charcoal to it…
Leaving meat juices inside the grill
The salt in these juices corrodes metal parts over time. You should always empty drip pans after cooking or be sure to clean them after every use. Generally speaking, you should never have water standing anywhere in your grill for longer than necessary – especially during winter months. Why? Because corrosion occurs faster at low temperatures and this certainly doesn’t look good if you have guests over!
An alternative way of cleaning your grill is to use a dry-chemical fire extinguisher and spray the hot grates while wearing heavy gloves and long sleeves. This should be done after you light your barbecue, while it’s still clean and cool enough to handle. The dry chemical will not cause rusting or corrosion because it blankets whatever it comes in contact with.
Not cleaning the grill often enough (or overusing certain products)
Cleaning your grill after every use should be common practice but you can’t just scrub off all that stuck food residue with soap and water! Most of that comes off easily anyway – it’s just black char from burnt proteins that doesn’t come off by itself (although some homeowners say they’ve been able to clean their BBQ simply by spraying it with a hose). The main culprits for this cause of grill molding are not suitable cleaners or too much scrubbing.
Using the wrong tools. Keep in mind that some cleaning products will eat away at your BBQ’s coating if they contain acid, so pay close attention to what you use. Baking soda and coarse salt will remove surface rust, but remember not to scrape off any protective layers on parts underneath the rust because they could be just as important as the rest of your barbecue.
The best way to clean stainless steel grates is with vinegar or oven cleaner (carefully read instructions on the label first) – never soap and water! Remember to spray whatever product you use onto cool grates only. Rinse thoroughly and dry with a non-scratching wire brush. The grates should be ready for another round of cooking after this, so you can wipe them off with oil or melted butter to prevent further rusting and the next time you grill, don’t forget to scrape off any food residue before applying more oil! Also, if you think your grate needs some extra cleaning that will not harm its protective coating (if there is one), we recommend using Bar Keepers Friend , which is good at removing everything from scorch marks to rust and corrosion.
Overcooking meats and other foods
You may notice smell and taste like mold every time you cook meat and vegetables – especially during winter months when humidity levels are higher. This happens when food is cooked at very high temperatures for a long time, allowing harmful fungi and bacteria to grow.
Not pre-heating the grill in summer
In summer you should never light up your barbecue right away because it takes a while for all that heat to dissipate! If you have an infrared bbq then this doesn’t apply, but if you use charcoal or propane then be sure to let your bbq heat up for around 10 minutes before cooking. This will also help prevent rusting – using cold metal grates against hot meats can cause major sticking!
Not cleaning vents during winter months
Your vents are important parts of your gas grill so please always keep them clean, especially when there is a lot of snow and ice around the house!
Not storing your bbq properly during winter months
When it’s -40 degrees outside, you should definitely bring in your grill when it’s not in use. This will prevent damage to any moving parts by freezing water and other liquids that may have snuck their way inside (guess what we found in one customer’s gas grill?). If you can’t store your barbecue in a garage or shed, at least make sure it is kept indoors overnight and only brought out when needed.
How do I stop my grill from molding?
What causes mold on grills? You are probably wondering how to stop your grill from molding. Mold is a common problem with grills, especially if you store them outside in damp areas during the winter months. To clean it effectively takes some time and effort on your part, but the results are worth it. Make your grill look like new again by spending a little time following this important process.
– Disconnect the unit from its power source before cleaning.
After disconnecting the grill’s power source, you need to remove all of the food particles or debris that have found their way into nooks and crannies throughout your grill over time with an old toothbrush or similar item with bristles that can reach deep within any cracks you see.
– Wash the grill with soap and water.
After you have removed all of the debris with your toothbrush, wash it with some soap and water to remove any leftover grime or residue. Use a sponge or soft cloth for this task rather than a brush, as bristles can also scratch up your grill’s metal if they are too firm.
– Dry the unit thoroughly after washing it.
You need to make sure everything is perfectly dry before going on to cleaning any further, so give it ample time to air dry completely before moving on. If necessary, use a blow dryer or fan to speed up this process if you’re in a hurry. It’s important that no moisture be present when you try to clean the grill afterwards, as this could result in mold.
– Scrub away surface mold with a plastic scouring pad or pot scrubber.
If you see any visible patches of mold on your grill’s exterior metal surfaces, use a plastic or wooden scouring pad or pot scrubber to remove it gently and completely. You can also use steel wool if necessary; however, make sure that both the pad and the steel wool are very fine and not too firm before doing so. If you accidentally cut into the metal while removing any small pieces of rust this way with a wire brush, then you need to start over by resealing it with some paint to protect it from moisture damage. Do not allow moisture near your grill if it has been cut, because rust can spread fast.
– Rub the grill with a generous amount of cooking oil after cleaning it.
After you’ve cleaned your barbecue thoroughly, make sure to wipe down its exterior metal surfaces with some cooking oil for protection against future mold outbreaks or corrosion that could result from moisture. Apply this coating carefully and gently so as not to scratch any part of your grill’s surface unless necessary. Then, just turn on the grill to let the oil bake into its metal before grilling again. You should apply this treatment each time you clean your grill afterward if possible, or at least once per season for best results. Be careful not to get any oil onto your food while grilling if this is what you use as a cleanser, however.
Recoating your grill with paint can help to keep it clean longer if you don’t have a lot of time on your hands or just want a good way to save some money without going through all of the trouble of cleaning it each time.
If you’re not willing to go through the process of scrubbing away surface mold every so often, then this is an inexpensive alternative that can be used instead. Spare yourself from what feels like endless scrubbing and apply a new coat of paint after prepping for painting as needed. This can also be useful if parts of your grill have been damaged over time by small rust spots caused by moisture exposure. Just make sure that the metal is free of rust and perfectly dry before applying any new paint to seal it.
A word of caution: If you do not clean your grill properly, you can cause more harm than good. For example, if you use a wire brush on your grill without removing the food particles and debris that have settled into its nooks and crannies first with a toothbrush or similar item, then this could damage the metal over time by stripping away some of its protective layers and causing small holes in them where rust can form afterwards. Also avoid using harsh chemicals as a cleanser unless absolutely necessary as they can also strip away at your grill’s protective coatings over time.
How to Prevent Molds from Growing on a grill?
What causes mold on grills? There are many ways to prevent molds from growing on a grill. To begin with, removing any leftover food particles from the grill is necessary in order to avoid any formation of mold and mildew. Remove the ashes and debris left over after cooking and scrub off any build-up or grease before putting away the grill for storage. If there has been no use for several days, regularly flipping the grates may help prevent mold growth. Leave them upside down if not using regularly; this ensures that rain does not collect inside (which leads to moisture) and mold spores do not settle into the cracks (where they can easily become trapped). It is also important to regularly clean out shelves and drawers in garages and kitchens where grills are stored.
To prevent mold, consider using a grill that is enclosed or that has an attached cover; these keep the chrome clean and shiny without exposing it to large amounts of airflow, which can allow molds to grow. It also prevents water/rain buildup which promotes moisture build up where mold spores can easily become trapped.
Any time you use your outdoor grill, be sure to clean it after every use. This will prevent the accumulation of food remnants and other debris inside the unit, as well as remove any possible mold spores before they have time to take root. When cleaning your grill after each use, scrub off any burned on food with a wire brush while the surface is still warm. As an alternative to using a wire brush, you can use a piece of aluminum foil that has been soaked in vegetable oil or cooking spray. Allow the surfaces to cool before scraping with a steel grill scraper.
In order to prevent mold from growing on your outdoor grill take the time to thoroughly clean it after each use. Keeping grills clean is essential in maintaining both their appearance and efficiency. In addition, regular cleaning will avoid the problems caused by food remnants and other debris getting stuck between parts of your grill that would not be able to come apart easily while hot, potentially causing corrosion if left for too long. To remove built up grease and food particles, you should scrub down your grill with a wire brush while it is still warm. Alternatively, you can use a piece of aluminum foil that has been soaked in vegetable oil or cooking spray. Allow the surfaces to cool before scraping with a steel grill scraper.
For built up ash and debris inside your carbon steel outdoor grill, soak it in warm soapy water overnight before cleaning it thoroughly the next day. For particularly difficult-to-remove dirt and residue, pour on some baking soda followed by vinegar (1 cup vinegar for 1 cup of baking soda) into your grill’s interior then scrub clean with either an oven cleaner safe scouring pad or nylon brush. Do not use steel wool which will scratch off the protective coating of carbon steel; therefore negating its non-stick properties well as making it susceptible to rust.
In addition to preventing food from getting stuck in your grill, thorough cleaning helps prevent any mold spores present from taking root and growing on the surface of your unit while it is not being used. In order to clean molds off a grill or any outdoor cooking surface, mix soap with water and spray it over the entire area of interest. Scrub thoroughly with a wire brush before rinsing away all of the suds with a hose. For particularly difficult areas that may have become slightly discolored due to mold growth, you can scrub them down with a paste made by mixing 3 parts baking soda and 1 part salt; alternatively you can make a paste using 2 tbsp chlorine bleach per quart (32 oz) warm water. Once scrubbed and rinsed, the surface should be dried immediately to prevent any water from pooling and leading to corrosion.
Although outdoor grills are designed for outdoor use, long term exposure can cause them to rust and corrode, especially if they are not properly taken care of. If there is a grill cover available for your particular unit, using it can help protect it from both mold spores as well as rain and moisture build up which will insure that there is no chance of rust or corrosion forming on the exterior surfaces. Using a grill cover also helps keep debris such as leaves and twigs off the exterior ensuring that there is nothing settling into cracks or crevices that might lead to corrosion. It also prevents rain buildup which leads to rust formation as well as preventing the growth of mold.
In addition, caring for your grill by dusting it down after each use will also help protect it from longer term issues such as corrosion and rust. After you have finished cooking on your grill, let the unit sit until completely cooled before storing it in a dry place out of direct sunlight. If left out in the elements at all times, moisture can form between the outermost layers of enamel which begins to work its way into the surface leading to flaking or cracking that will allow rust to begin forming. In addition to protecting your outdoor grill from diseases such as black spot fungus, taking care by cleaning and storing your grill indoors will not only prevent potential health concerns but will also increase the lifespan of your outdoor grill.

What Temperature Kills Grill Mold?
Grill mold can be a big problem for backyard chefs and picnickers with its unsightly, black splotches left behind on food cooked on the grill. Even worse, this food-borne pathogen is tough to clean off because it has root like structures that stick to the surface of the dish – much like tree roots grip soil as they grow. Is there an effective way to kill grill mold and make sure it will not return?
Exposure to high heat is one of the best ways to kill bad bugs such as E coli and salmonella. However, most pathogens will not be affected by heat alone and may return once the item cools down. This means simply grilling or roasting meats will not kill most harmful bacteria.
To effectively kill grill mold, the dish must be heated to 250 degrees Fahrenheit for at least two hours in an oven or on a stovetop burner. After heating, allow the dish to cool slowly before using it again. A grill, barbecue pit or smoker can also be used to cook food items but cannot heat them hot enough to ensure that all of the black gunk is killed off.
If you are unable to heat the dish above 250 F for at least two hours, there are alternative methods of killing off grime and mold. These include immersing dishes in a bleach solution (one tablespoon of household bleach per gallon of water) for thirty minutes or more before rinsing thoroughly with clean water and allowing air dry. The dish can also be soaked overnight in a solution of two parts hydrogen peroxide to one part water before washing with soap and water. Rinse well with clean water and allow the item to air dry as mentioned above.
Importance of Cleaning your Grill
No matter how great your food is, if you don’t properly clean your grill after cooking on it, everything from then on will taste like old ashtray. Your dish will not only taste bad but can also contain carcinogens from an uncleaned grill surface. During normal grilling, smoke particles are deposited on the grill surface. As these particles build up, they release a bitter flavor into whatever product you’re grilling next time.
Clean Grills Mean Better-Tasting Food
What causes mold on grills? Cleaning your grill regularly can ensure that it doesn’t become a source of contamination.
To clean your grill, you want to use a wire brush and wipe down the surface after each use. However, this does not physically remove all food particles from the cooking grate. You will then have to apply some sort of nonabrasive cleaner using a long-handled plastic bristle brush or a coarse sponge before continuing with a new round of grilling. This will help fight cross-contamination between products being grilled on the same device.
Clean Grills Mean Better Health
What makes people sick from eating cooked foods is due to bacteria contamination on surfaces used for both raw and ready-to-eat foods. Bacteria can spread quickly to other areas if it is not killed off by proper sanitation methods. If your grill is dirty, it’s no different than using the same surface as step ladder and cutting board at the same time!
Clean Grills Mean Better Tasting Food
Further, if you want to make better tasting food, clean your grill after every use; otherwise you might as well start eating uncooked meats since you’ve already got all those carcinogens in them anyway! Cleaning your grill helps remove potentially harmful particles that stay on its surface after cooking. You will benefit from doing this by having tastier food to eat during cookouts or for dinner because of the added freshness that it gives. And your friends and family will thank you for getting rid of all the old ashtray taste, too.
