Review (4/5): decent
apply this generously to each finger (make sure to put some under your nails as well) and spend 2 minutes scrubbing each nail nice and good and then rinse your fingers. Next, with the same nail brush or an old toothbrush, do the same thing with whitening toothpaste. You can repeat these steps if you need to but I didn't! I'm a smoker and a tanner with yellllloooowww nails and this did the trick. Nothing's more embarrassing then some ragged looking yellow finger nails.. Enjoy!
oh- I also heard that denture tablets work wonders too!
