Pumice, then Alcohol
Wet hands immediately in water (cool or warm---not hot). Apply pumice soap to palms. Many kinds of pumice soaps are sold in dispensers but others (Lava, for example) are also sold as bar soap.
Rub hands together vigorously. The abrasive action of the pumice will rub the older, dry (and discolored) skin cells off the hands. It will also get much of the stain out of the pores.
Scrub under your fingernails with a nail brush. You may have to do this for several minutes. You can also use this brush, along with the pumice soap, to scrub away any stains that remain.
Rinse the pumice soap from your hands. Use a paper towel to wipe any remaining stains with rubbing alcohol---this works particularly well if stains are from ink or paint.
Remove alcohol from your hands by rinsing under cool water. Dry your hands well. Apply hand lotion to prevent your hands from becoming sore or chapped (from the scrubbing).
Things You Will Need
- Pumice soap (Examples include Lava soap and GoJo)
- Fingernail brush
- Paper towel
- Rubbing alcohol
- Hardware stores and automotive supply stores sell industrial-strength pumice soaps. If hands are very stubbornly stained, you may need to wash this way several times to completely remove the stains. Just make sure to give your skin a break in between washing or it may become very raw and sore.
