Article: Dip a Q-tip in nail polish remover or rubbing alcohol. Use the Q-tip to lightly dab at the stain or mark on the gel nail, being careful not to vigorously rub so that you don't remove the gel color. This works best if you use the nail polish remover or rubbing alcohol very soon after the stain appears on your nail. Lay a towel down on a table and place your hand on top. Spray hairspray over the nail with the stain until the nail looks wet. Use a Q-tip to remove the hairspray, which should remove the stain as well. Wash your hands well with soap and water to get the hairspray off of your hand. You shouldn't need to rub the gel nail harshly to get the marking off of it. Fill a regular-sized bowl with water and add 3-4 drops of tea tree oil to it. Place the gel nail that needs to be cleaned in the bowl, letting it soak for at least 5 minutes. Wash your hands after removing the nail from the mixture. If the stain is still there, do the same process over again once a day for several days. Sometimes a mark or stain on your gel nail just won't come out using at-home remedies, which is when it's time to turn to professionals. See if your nail salon will redo the one nail that was damaged so that your nail will look good as new. Some nail salons will do this for free while others will charge a small fee, so ask your nail salon before committing to redoing the nail.
