I had on a blue polish that stained my nails as you can see and wanted to use this instead of my usual file & soap routine. In short, the directions calls for you scrub your nails with the solution (which reminds me of baking soda). You're to leave it on for 5 minutes then wash it off... I did that!!
After I washed it off I see no difference, do you?
So I resorted to my usual stain removal routine...
After that I just shined it up with some cuticle oil and I was good to go. In addition to my routine, I sometimes I like to use whitening toothpaste.
Needless to say I'll be sticking with my usual routine. Do you have an easy stain removal process? I'd like to know about it.
