There's really no need to keep giving baths at all unless he ended up with a stuck shed that you need to assist in removing. And mine usually take around a week to complete the process. They will get dark, the eyes will turn blue, and then they look normal for a couple days, and then you should find the shed in the enclosure soon after. As long as you've got your humidity high enough, they do a great job of taking care of business all by themselves.
