If you read Do Just One Thing on a regular basis, you know my love for all-natural white vinegar. But there are some things you should never clean with white vinegar. Natural stone countertops like granite and marble should never be cleaned with vinegar; it’s too harsh and can cause etching on the surface. And the same goes for hardwood floors; the seal that keeps floors protected with a sheen can be damaged by the mild acid in white vinegar.
