1 cup borax
1 to 2 tsp. pure turpentine
1 tsp. sweet orange essential oil
1 cup ground soap
With very clean hands, work the turpentine and essential oil into the borax until there are no lumps left, next add the soap. Keep it in a wide-mouthed jar or tin that’s easy to open when your hands are greasy, something you won’t mind getting dirty on the outside. A nail brush and pumice stone also help with the hand cleanser.
