If it were July I'd be happy to use the power washer, but since it is freaking freezing outside, and I typically get very wet when I use that thing, I'm going to try running them through a cycle in the dishwasher and see what happens.
By the way, I used a cup brush on the inside of the firebox earlier today, you guys who do that are PSYCHOS!!!!! The bristles started coming off about when I entered the ninth dimension due to the acupuncture effect they were having on me and before I knew it Thanksgiving already happened. Is it July now actually? Holy crap, I NEVER want to use a cup brush on the inside of a grill again.
