On the second wash lather up well but don't rinse off the soap. Pat hands dry..gently.
An hour or so later tell folk you never buy soap as your skin miraculously creates its own soap. To prove it put your hands under the tap of warm water. Soap bubbles will appear.
You will then spend the next couple of years going by the nickname of Bubbles..... :-(
There is no set of rules on it. You can wash them as many times as you think for what you have been doing with them. As i guide once for normal soiling and twice for unhygienic soiling.
