Bonnie: Use it as it comes out of the wrapping. I use it dry, just rub it on the cramp area when it occurs. If you don't like the residue that it leaves, you can wash it off after the cramp is gone. I don't wash it off. But there is no reason you can't wash it off. I keep the soap next to my bed because I mostly get the cramps in my legs at night.

Some people leave the soap under their bottom bedsheet and it works for them that way. I also use it to calm the arthritic pain in my shoulder. I hope it gives you some relief!
