How to Clean Battery Acid From a Concrete Floor

Battery acid (usually muriatic or hydrochloric acids) is a strong caustic (PH 0-1) which will permanently etch concrete and other materials. The depth of a hole eaten into concrete by acid depends on the duration of contact. If you spill battery acid from a lead-acid car battery on your concrete floor, there are a number of steps you can take to neutralize the acid and minimize the damage.

Step 1

Mix three parts baking soda with one part water in a bucket to make a paste.

Step 2

Pour the paste onto the battery acid until the acid no longer bubbles.

Step 3

Wipe up the paste using a disposable cloth.
