How do you clean your children's toys?

[lisamai]

I just realized that I haven't ever really cleaned my 3 year old's toys. But now that my 6 month old daughter is putting everything in her mouth, it's making me worry! What's the best way to clean them all easily? I was thinking of putting them in a bathtub, but what soap/cleaner would be effective in getting grime/dirt/germs and whatever else is on there off, but still be safe to put in a baby's mouth?
I'm talking about little action figures, legos, cars, animals - mostly plastic items.
