Lately some medication that I've taken has made my nails have an unappealing yellowish color, and it's noticeable to others now, so I'd like to find a way to make them look normal again. I'm a guitar player and artist, so my nails get scuffed up daily and polish chips off quickly. I would love to learn about tricks to make them look shiny and clear again without having any polish on them. Would soaking them in a whitening mouthwash or something do the trick? Does anyone have any suggestions?
