Take the substrate out and use paper towels for now, leave it in the sun for a day. That what I did the last time I decompressed eco earth and it was fine.
Preparation takes up a lot of time, it's pretty much an all-day thing. You could also try baking it to dry it, but I've never done that.
I would never put my snake on moist substrate. If you notice signs of scale rot, take your snake to the vet asap and keep him on paper towels.
