Just make sure everything is completely dry before you put the rats back in, I wouldnt want them to get any flare ups in their respiratory system.

I remember reading here about using frontline on pinks and such. Since they are so young, you may be able to get away with using the adult cat stuff (not really sure), and dipping your finger in it rubbing your hands together and lightly going over their fur. Don't quote me on that.
