But for those feint of heat and sensitive of nerve endings, wear gloves. And before you put on those gloves wash your hands with plain ol ivory bar soap 99.9% pure, Get a thick soapy lather but don't rinse. Let the soap dry as a film on your hands. You won't even notice it but it will be an effective barrier against practically anything. When you are done wash it off and away goes the pepper juice with it.
It's actually an old printers and mechanics trick for cleaning up after work, but Mom uses it when canning horseradish or hot peppers. Personally I never had much of a problem with hot peppers, but horseradish will seriously burn you.
