Things You Shouldn't Clean With Vinegar
While vinegar is safe for most surfaces, it isn't safe for every surface. Avoid using vinegar on natural stone countertops and floors, like those made of granite, marble, and quartz; it will etch the stone. You should also avoid using vinegar on unsealed grout or grout that needs to be resealed again. Waxed surfaces are a no-no, too.
Opinions are mixed about whether vinegar is safe to use on wood floors. If you decide to try it, dilute the vinegar in an equal amount of water and do a test spot before tackling the entire floor.
