Putting this in my oven as we speak! Beth Easy oven cleaning- heat oven to 150 F . When it's hot, place a cup of ammonia in an oven safe dish on the top rack and a pot of boiling water on the bottom rack. Leave overnight and clean out oven in the AM.
Ammonia to clean stove grates. 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.
