I could be wrong here but my understanding of the Epsom Salts use is to:

1. Empty the acid from the battery, then
2. Add the Epsom Salts solution and allow it to soak in the battery, then
3. Empty the Epsom Salts from the battery and flood the battery inside with
water and empty. The object here is to try to empty out the detached
debris.
4. After rinsing then refill the battery with new acid.

I agree with Rabbitreborn about charging a battery with Epsom Salts in the cells being dangerous. And I also agree that trying to renew a battery is like trying to make a cat bark.
