Anyone who uses a nail buffer regularly will notice a buildup of dust and debris on the buffer over time. A nail buffer smooths and shines the surface of fingernails and toenails. It is possible to remove the dirt from some nail buffers. Nail buffers made from paper, or that have a paper coating, aren't washable, but nail buffer blocks made of other materials, or electronic nail buffers, permit washing. However, only the tip of an electronic buffer should touch water.
Spread two or three drops of mild liquid hand soap over the nail buffer block.
Hold the block under warm water.
Scrub the block clean with your fingers.
Rinse the block with warm water.
Set the block on a towel to air dry.
Remove the buffing tip according to the item's instructions.
Wipe down the outer portion of the nail buffer with a wet wipe.
Spread one drop of liquid hand soap onto the buffer portion of the tip.
Scrub the tip with your finger under running water. Rinse it with water.
Lay the tip on a towel to dry. Do not put it back in the electronic nail buffer until it has dried completely.
