My experience with moisture from a cover is not about water on the cover and how well the cover protects/repels things. It's more about the covers trapping moisture (any moisture in the air) in the grill, as the first point in your post here.

I'm not saying it's completely containing and filling the grill with moisture though it can tend to maintain some in more humid times. For me, this isn't some mold situation and I keep my grill clean though I am starting to believe it's encouraging some rust.

Do you have any thoughts or ideas on that? I've seen some covers for larger grills with vented flaps at the top which are advertised to help with high winds by letting air that blows under the bottom of the cover escape at the top. Though I'm also wondering if they would help the grill breathe some and any humid air escape easier...

I appreciate your comments Ray, as I stated in the article, "NEVER cover a grill that's already wet...." That includes any kind of moisture, humidity, foggy conditions, etc. Your concern seems to stem from instances of rain between grilling sessions, with the wetness getting under the grill where it contacts the surface, be it a deck, balcony, patio, etc. A good wipe down and a clean grill with vents closed, coupled with a properly fit cover placed on a DRY grill should alleviate any concerns you might have with premature rusting or possible drafting of moisture upward into your grill. And the vent flaps on grill covers you've seen, that's a marketing ploy pretending to prevent covers from blowing away in high winds. All those 'vents' do is drive up the price. If you properly secure the cover with a bungee cord or two (I don't rely on a the Velcro straps sewn on the cover), There's no need to have any vent flaps on a grill cover and they do nothing whatsoever for moisture ventilation. Think about it, if it can 'release' moisture, it would also let it seep in. It's a hole in a grill cover.

Here's another tip to help preserve your grill: Brush or spray the legs of your grill with a clear coat. Don't spray your grill, as the clear coat can't take the heat, focus on the legs. A clear coat helps preserve the metal, no fading, no oxidation, no rust!

I have stainless steel grates that I can’t get clean. The grease is gone but rust is on the grill. Any thoughts on this? I am concerned about cooking on them for my health. Jeanette

Mike Thayer

You can try baking soda, water and crumpled up foil, provided the rust is only on the surface. But I would recommend new grates.

Can I use armor all on my grill cover after I clean it?

Can I use a steamer to clean the grill itself?

Thank you!
