We use this household product on ourselves when we have a cut or scrape. Some people use to clean their ears with it, and some people swirl it in their mouths when the have a mouth sore or tooth infection. It’s a natural whitener which is why its an active ingredient in toothpaste. But Clean and Pink uses this fabulous product to get tub stains out, uses to clean shower grout and tile, and soap scum. Give it a try and if you don’t want to clean it, Clean and Pink will be happy to clean it for you.
