My little trio I'm raising are in desperate need of a bath. No matter how well I think I get formula off, I miss some and parts of their fur is stiff with the dry formula. They also have some poo smears from being in a feeder bin I couldn't get off with a wet q-tip. I will be waiting until their eyes are open but they are really going to need a bath. Is regular dawn dish soap safe to use on them? Advice would be appreciated as I just can't get it off with wet wipes or q-tips.
