I thought we had a writeup in the DIY but alas, I don't see it anywhere. If you want to clean it in place, any decent de-greaser should be fine. taking it out and soaking it would be better, but it depends on how much of a project you're looking for. (if memory serves me, I think the entire door needs to be disassembled to get at the latch? it's been many years since I had to do that)
