How do I remedy 'yellow nails'?
You can get rid of yellow nails by using a soft, coarse file because the nails are much stronger than the finger nails. You can file on the toenails more than you could on your natural nails, or take a light buffer and just buff the top of it until the yellow goes away and that toenail is thick enough where you're able to apply that type of pressure on the nail bed. If you have a yellow finger nail, sometimes acetone will remove it or lightly buff the nail. Get into the habit of using a base coat to avoid having to file your nails at all.
