Salt might not look rough, but it's actually quite abrasive. If you've got grimy or greasy cookware, sprinkle enough salt to lightly cover the bottom of your pan. Then, take a damp scrub brush or sponge and scour the pan. Rinse the salt off and wash your pan with hot, soapy water to completely clean it.^{[1]

- Although salt is great for cleaning pans like cast iron skillets, don't use it on non-stick surfaces or you could destroy the coating.

Mix equal parts salt and vinegar in a bowl and pour it into a spray bottle. Shake the bottle really well before you spray the cleaner on counters, tables, or surfaces in your kitchen or bathroom. Once you spritz the cleanser on, rub it off with a damp sponge. Rinse out your sponge and wipe again to remove the cleanser.^{[2]

- Vinegar is a weak acid, so it's really helpful in a cleaning product. It can lift dirt and stains, especially when you combine it with salt.
- If you have stuck on messes, go ahead and sprinkle salt directly onto a damp sponge. Then, scour the surface until it's clean. This is great for cleaning tile or grout, for instance.^{[3]

Get rid of odors by rubbing half a lemon dipped in coarse salt across the board. The citrus juice will work with the abrasive salt to fresh the board. This is really useful if you've just cut something smelly like onions or garlic on the board. Rinse the board with cold water and dry it thoroughly before you store it.^{[7]

- Keep in mind that salt and lemon won't sanitize the board so you'll still need to wash it with hot, soapy water if you've cut raw meat or seafood on it.
