Tutorial on How to Acid Wash a Pool

Drain your pool by removing the drain plug and siphoning the water to the correct water disposal area.

Scrub the pool while the water is draining to remove as much of the algae and leaves as possible.

Bag up any leaves or loose debris at the bottom of the pool.

Plug the drain of the pool to prevent acid from washing down the drain.

Add 1 gallon of acid, available at pool supply stores, to 1 gallon of water in a watering can. Add the acid to the water to prevent splashing.

Pour the acid down the side of the pool walls from top to bottom, one 10 foot section at a time. Let the acid sit for 30 seconds then brush using a specialty acid brush.

Rinse the walls of the pool every 30 seconds to wash the acid towards the drain and prevent damage.

Add 2 pounds of soda ash for every gallon of acid you used into the puddle of water that collects by the pool drain. This neutralizes the acid. Remove the drain plug to drain the neutralized water completely.
