River Rock For Scrubing/Removing Dirt and Dead Skin

First of all, this is one of my late granny's tips. I'm not sure anyone of you have tried this. But it really works for me. Usually, people uses a pumice/scrubber to scrub and remove dirt and dead skin cells off the body in the shower or while taking a bath. But I use river rock!! You can just pick a good rock from the river. I've been using it since I was a teenager. To scrub, you have to scrub a little hard to get dead skin or dirt off the skin - but not too hard. Do it once a week. It might hurt for the first time. But once you get the hang of it, it should be ok...
