Minerals in hard water and rusting hardware can stain a tub. A good tub is a clean tub–though the stains won’t hurt you, they just don’t look very nice. This formula dissolves stains with an item that lives in the pantry: Cream of tartar! It’s a pure by-product of winemaking that’s used as a stabilizer in cooking and is a main ingredient in baking powder.
2 tablespoons cream of tartar
1 to 2 tablespoons 3 percent hydrogen peroxide
Mix the ingredients into a frothy paste. Scoop some onto a sponge or scrubber sponge and scour the stain thoroughly. Rinse.
For stubborn stains, let the past sit on the stain for 15 minutes, then scour and rinse.
Note: Use this recipe within a few hours of preparing it or the hydrogen peroxide will become inactive.
Saving the Planet One Scrub at a Time
According to the Seventh Generation company, if every American household replace just one 32-ounce bottle of chlorine-based bathroom cleaner with an eco-friendly, chlorine-free product, it would prevent 1 million pounds of chlorine from entering our environment.
