The Unexpected Vegetable You Need To Remove Stubborn Stains From Your Hands - Tasting Table

"The surface of a raw potato contains properties that can apparently remove stains from things like berries, beets, and other plant materials. The big player here is oxalic acid, a natural compound that reacts with dark stains, including rust, and lifts them from a surface. Raw potatoes also have chlorogenic acid, which breaks down dirt and mud, and starch, which is very absorbent and slightly abrasive."

"To try it out, just cut a raw potato in half and rub the surface all over your hands, holding them over the sink. Scrub any particularly stubborn spots just like you would with a sponge or brush, and watch the magic happen. The stains should lift within a few minutes. Then just wash your hands as normal to remove any residue."

Raw potatoes effectively remove stubborn food stains from hands caused by pigmented foods like beets, berries, and spices such as turmeric and curry powder. The potato's surface contains oxalic acid, which reacts with dark stains and lifts them away, along with chlorogenic acid that breaks down dirt and mud, and starch that provides absorbent and slightly abrasive properties. To use this method, cut a raw potato in half and rub it over stained hands held over a sink, scrubbing particularly stubborn spots as needed. The stains typically lift within minutes, after which hands should be washed normally. Salt or baking soda can be sprinkled on the potato for enhanced cleaning power on other kitchen surfaces.
