If you soak pre-shed you will probably cause problems with the shedding process. You only want to soak post-shed to get off the access shed that he missed.
If it was that early in the cycle, it may not have affected anything, so just wait and see. After he turns blue he'll turn clear, then shed a few days after that. The clear stage is of a special fluid filling up in between the new and old skin preparing it to be shed off.
Good luck! :]
