How do you get nicotine off your fingers?
You can use toothpaste and then use a toothbrush or nail brush to get nicotine off your fingers. Another thing that is supposed to work is soaking your fingers in a glass with water and Polident.
Dishwashing liquid and a nail brush works pretty good too. To keep it from building up though you just need to wash your hands more often and use lotion to keep the skin from drying out.
Try lemon juice
or u can put bleach in a bowl mix with water and soak your fingers in there for about 5 minutes
