Everyone who owns a gas stove, pin this!! It works! Mine were absolutely disgusting and I tried everything to clean them. It was so gross how much came off! Definitely the best stove grate cleaner ever.
Okay, this stuff is AMAZING! DIY shower cleaner -- vinegar and dish detergent. Don't worry about the brand or color. We used clear store brand detergent and it was GREAT! NO SCRUBBING required. As long as you can tolerate the smell :)
