As it turns out, hand sanitizer doesn't stain clothes. It actually works as a stain remover.
The quick and easy way to remove stains on our clothes is to use hand sanitizer. All you have to do is cover the stain with hand sanitizer. Then, allow the gel to set for 10 minutes. Next, clean the fabric as normal in a washing machine. Just be sure to use hot water. After it’s done washing the mark should be gone.
