How to Neutralize Pool Acid Wash

Locate the foamy puddle that formed near the sloped drain of the in-ground pool. This puddle needs to be neutralized prior to removing it from the pool because the acid can damage drain pipes.

Broadcast two pounds of baking soda across the puddle for every gallon of acid you used to clean the pool. For example, if you used a half-gallon of muriatic acid to wash the pool, then you should use one pound of baking soda to neutralize the leftover puddle.

Stir the baking soda into the puddle with a pool brush. The one you used to scrub the pool is good to use. This will neutralize the brush itself also.

Connect a small submersible pump to remove the puddle from the pool. Connect a standard garden hose to the pump and lead it to the yard's nearest drain. Plug in the pump, turn it on and place it into the puddle. Avoid getting the water on plants and grass.
