The ancient Greeks used pumice to remove body hair, and some still use it for this purpose. Pumice makes a gentle natural hair remover. Soak your skin in the bath or in a shower until it's warm and soft. Wet the pumice stone, then rub your skin using a gentle circular motion. Within about 30 seconds, the area you're rubbing will be free of hair.  The effects of pumicing are similar to the effects of shaving. The hair is removed close to the skin, rather than being pulled out.  Pumicing should not be painful. If you feel pain, make sure you aren't pressing too hard. The soft, porous surface of pumice is perfect for taking pills and lint off of clothing. If you have a sweater you've been wanting to clean up, lay it on a flat surface. Rub a dry pumice stone over the pills in a circular motion. Don't press too hard, since you don't want to damage the fibers of the garment; a gentle pressure is all that's needed to take the pills right off. Pumice can be used to remove copper rings from the inside of a toilet. Put on a pair of nonporous cleaning gloves to start. Then simply rub the pumice stone over the ring using a scrubbing motion. Repeat until the ring is gone.  You can use the stone in combination with toilet cleaner for more stubborn stains. Be sure to use separate stones for toilet cleaning and body use. Do not use the same stone for both purposes.
