Well.... dishwasher. But I've said this before, so
check the archives.
Probably a FAQ top 10. But what happened to the FAQ?
http://www.classiccmp.org/faq.html
"be warned: the... FAQ hasn't been updated since 1997"
Actually it's kinda sorta in there:
http://www.classiccmp.org/oldfaq.txt
"I find a cycle through the dishwasher does a really nice job on keyboards."
I don't think the rules preclude discussing the FAQ until 2007.
