Over an empty sink, in a ventilated area and away from open flame, carefully rub solvent over hands, or use a shop rag with a small amount of spirits to wipe your hands.
Immediately wash your hands with soap and warm water. Try a dish soap, such as Dawn, to break down the sticky polyurethane. Rinse your hands and dry them.
If you still have some sticky spots on your hands, try rubbing baby oil, moisturizing lotion or peanut butter onto them. Lather them as you would with soap. Rinse again with dish soap and warm water.
Once polyurethane is removed, your hands may be dried out from excessive washing. Apply some hand lotion to soften the skin.
