Frequently Asked Questions

How often should I deep clean my BBQ grill?

Deep clean your grill every 5-10 uses or monthly during peak grilling season. Light users can extend this to every 2-3 months, while heavy users may need weekly deep cleaning.

Can I use oven cleaner on my grill?

Only use oven cleaner on the interior firebox of gas grills, never on grates or areas that contact food. Always check your manufacturer’s recommendations first, as some coatings can be damaged by harsh chemicals.

What’s the best way to prevent rust on grill grates?

Keep grates clean and dry, season cast iron grates regularly with high-heat oil, and store your grill in a dry location with a quality cover. For stainless steel grates, regular cleaning and proper drying are usually sufficient.

Should I clean my grill grates while they’re hot?

Clean grates when they’re warm (not hot) for easier debris removal, but ensure they’re cool enough to handle safely. Never use water on extremely hot grates as this can cause warping or cracking.

How do I know when to replace my grill brush?

Replace your grill brush when bristles become loose, bent, or start falling out. Inspect before each use and replace every 2-3 months with regular use, or immediately if you notice any bristle damage.
