Make a sugar scrub. Mix sugar with olive oil. Rub it all over your hands for two minutes.
Rinse with warm water. The sugar crystals lift the dead skin. The oil moisturizes at the same time.
Do this twice. Your hands will look like they never saw a tan bottle. Magic? No. Science? Sort of.
Vinegar: The Secret Weapon
White vinegar is a tan killer. Mix equal parts vinegar and water. Soak a cotton ball and wipe your hands.
Let it sit for 30 seconds. Rinse immediately. The smell is gross, but it works fast.
Pro tip: do this over the sink. Not near your eyes. Unless you want to cry and smell like a salad.
