Mechanical Keyboards

Basically title: What is the preferred or most efficient way of cleaning light colored key caps?

I'm guessing that putting the whole keyboard in the dishwasher is probably out.

Do you all just pull all the keys and clean them with a towel or something in a mild soap solution?

This would give me a good chance to be disgusted by all the hair and junk that accumulates between the keys too, so there's that.

Thanks for the help, and sorry for the newbie question, but someone's gotta ask them.
