It sounds like you have already removed your nails but there is still glue on your natural nail. The best way to remove the glue is to soak your fingers in acetone or acetone-containing nail polish remover for 15 minutes. Then gently file with a clean nail file the glue off your natural nail. You should then soak your nails in rubbing alcohol for 5-10 minutes to clean the nail bed area and don’t forget to apply lotion to your nails to keep the skin around your cuticle healthy.
It is very important to keep your nails healthy to avoid nail infections. Nail infections are very common and often overlooked. Nail infections can manifest as yellow nails or black discoloration of the nail area. If this occurs, schedule an appointment with your doctor because you may need to be put on medicine to avoid spread of the infection. Artificial nails can be a source of bacterial and/or fungal infection.
Here are some nail hygiene tips:
Wash your hands regularly. It is best to trim your nails weekly, but be careful to not trim them too short which may traumatize the skin around the nails. If you do have artificial nails, be even more careful to wash your hands. If your fake nail starts separating from your natural nail, soak your nails in alcohol before reapplying your artificial nail. This will help ward off germs which can cause infection. If you do have your artificial nails put on at a salon, it might be worth the time to inquire about the sanitation standards of the salon. How do they clean their equipment and how often? Have they had problems with customers getting nail infections? If you get pedicures, how often do they change the filters in their foot massagers?
Toenails should also be kept trimmed and clean. If you use a locker room/gym facility, it is best to wear shoes at all times to avoid contact with the floor. Keep feet clean and dry and wear cotton socks.
