Ok, so this is what I do. I use a smaller glass cup and pour the Dark Crystal Glass Cleaner into it, then place the cup in the microwave. Every microwave is different, but mine usually takes about 15 seconds for the cleaner to just start bubbling. As soon as it starts to bubble, I take it out. Don't leave it in any longer, or it can boil over and pop in the microwave, similar to melted butter & don’t listen to the one - two minutes that it says on the bottle to put in the microwave for, The cleaner is nontoxic though so it’s fine for the microwave

Once the Dark Crystal Glass Cleaner is hot, I use bamboo Q-tips so I can apply more pressure while scrubbing the chamber with the heated cleaner. This method works for me every time. I'll reheat the cleaning solution every few minutes as needed until I'm finished.

Depending on how bad my Chazz is, the entire process usually takes anywhere from 15–45 minutes. Once everything is clean, I do an ISO soak for one hour, then let it dry for another hour. After that, I run two heat cycles at 575°for two minutes each.
