About 4 hours if you use lots of spray cleaner B-12 chemtool spray works great, but you need to use an old toothbrush to speed it up. I could see it taking all day if you soak them, but I'm most concerned where the ports become smaller. Oh yeah, a whole role of good blue paper shop towels is good to have on hand.
