I had heard of doing that before somewhere in a woman's magazine (I think!).....except the method I read about used a washcloth.
Question - how long does the half of a sponge last before you toss it and start on another?
I think I would rather use the sponge rather than a washcloth.
I do believe the next time I am at Wally World, I am going to pick up some sponges!
