Remove cement stains from sandstone slabs

If you have cement stains on your sandstone, don't fret. There are methods for removal.

One of the best methods is to clean it with muriatic acid, otherwise known as hydrochloride acid. You can simply dilute this solution with water to remove the cement from your sandstone. However, this needs to be done with caution, as acidic cleaners can break down dolomitic cement or calcite, which holds many types of sandstone together.

It's a good idea to test out a small portion of your stone before moving on to the rest. You can dilute four parts of water and one part of muriatic acid to test out your stone. If the diluted acidic mixture doesn't fizz when it hits the surface of your sandstone, you're probably good.
