I’ve always found it ironic that the places in our homes that should be the cleanest—the washing machine, kitchen sink, bathroom tub, shower, sinks—are often the dirtiest.
Harsh chemicals, soap deposits, food stains, rust, hard water minerals, and water spots, when allowed to build up, will eventually not only look bad but cause permanent and irreversible damage.
The good news is that you can halt—even reverse—much if not all of this kind of damage.
DE-STAIN SURFACES. Erase those orange and brown streaks and spots with a paste made of 1/2 cup powdered borax and the juice of one-half lemon (or the amount needed to make a thick paste). Dab a clean sponge in the mixture, rub over the stain. Once you see the stain fade, rinse with running water. This works like magic on sinks and tubs made of porcelain enamel, stainless steel, or any other material. An old, stubborn stain may require multiple treatments, allowing the mixture to sit on the stain for a few minutes before rinsing. (It’s always a good idea to test any treatment like this in an inconspicuous place, first.)
