Kosher salt, as well as other salts, can be used for cleaning in a number of ways. It is a nontoxic alternative to chemical cleaners and can be used to clean areas and items used for food preparation. In some cases, it can be used as an abrasive cleaner for removing tough stains; in finer grades it is used in natural toothpastes to clean teeth and disinfect the mouth.
Cleaning Cast Iron Cookware
Kosher salt can be used to clean cast iron skillets and pans without ruining the seasoning that coats the cookware and prevents food from sticking. Salt is sprinkled on the bottom of the pan or skillet, just enough to sparsely cover it. If the pan is oily, salt can be left for a few minutes to soak up residue oil. The salt can then be rubbed on with a clean cloth or greaseproof paper as an abrasive cleaner to remove the residue cooking oils and food from the bottom of the pan. The pan is then rinsed with cool water.
Removing Rust Stains From the Bathtub
Salt can be used with lemon or lime juice to remove stains on bathtubs caused by a dripping faucet. These stains are often hard to remove, requiring harsh chemical solutions. As an alternative, the juice of one lemon or lime can be poured or squeezed over the stained area on the tub and then 1/4 cup salt can be sprinkled over and left to sit for up to four hours. The area is scrubbed with a nylon scrubber to remove the lemon and salt solution, along with the rust stains.
Using Salt to Soak Up Oven Spills
Kosher salt can be used to soak up spills in a hot oven caused by hot sauces or gravies bubbling over. The salt is sprinkled over the spill while it is still hot to prevent it from burning and becoming encrusted onto the oven making it harder to clean later. The salt is left on until the oven cools and then it is wiped up, leaving the area easier to clean. Salt helps prevent spills from smoking while the oven is on.
Using Salt to Remove Stains
Salt can be used to clean stains such as those caused by red wine, blood and perspiration. It is also used to absorb grease stains. It should not be used on leather or car upholstery as it can actually stain these materials, and due to salt's abrasive nature it should not be used to scrub mirrors, glass or plastic unless completely dissolved in water.
