How Do I Acid Wash My Swimming Pool?

You have decided to acid wash your swimming pool yourself, you have the list of items that is required to get the job done, and maybe you even already purchased them already. Now, where do you do first? How do you acid wash your swimming pool? I will be providing a step-by-step guide to walk you through the process of acid washing a swimming pool.

Step 1: the acid wash process is started by first emptying out the water in the swimming pool. You need to drain your pool and clean out all of the debris or dirt you encounter on your way. Draining the pool allows you to be able to work on the surface of the swimming pool without interference.

Step 2: The second thing to be done when the pool has been completely drained is to put in your protective gear. It is important to adequately protect yourself from the chemicals you’ll be working with because they can be harmful. Make sure you wear a pair of gloves, mask, goggles, and protective wear for the feet.

Step 3: the third is to prepare the acid that will be used. Add the acid to an equal amount of water in the watering can. The ratio of the mixture should be 1 to 1 to ensure it stays effective. Means you should add 1 gallon of acid to 1 gallon of water and on and on. It is also important that the acid should be added to the water and never the other round.

Step 4: the fourth step is to water down the surface of the pool to prepare it for the application of the acid solution. Make use of the hose to wet the surface of the swimming pool.

Step 5: pour the acid solution into the watering can on the surface of the swimming pool from top to bottom. Make sure you start from the deepest end and scrub the pool surface with the swimming pool brush as the acid solution is poured. Make sure you do this one section of the pool at a time.

Step 6: Rinse the section of the pool you just washed with water from the hose before you move on to another section. This is important because you do not want the acid sitting too long in the swimming pool so you have to work as quickly as you can to avoid damaging your swimming pool.

Repeat steps 4, 5, and 6 till the entire swimming pool is completely covered.

Step 7: Neutralize the swimming pool. Add soda ash to the puddle left behind after the acid wash. Use a brush to scrub this new mixture on the swimming pool. Use 2 lbs of soda ash for every gallon of acid that is used.

Step 8: use the pump and discharge hose to remove the mixture that is in the pool. Rinse the pool properly and remove all content in the pool. Dispose of the removed mixture properly as it can be harmful to animals that it gets in contact with. Always use a proper legal drainage channel.

Step 9: fill up your pool with water and test to make sure that the water chemistry is at the appropriate levels.


How Often Should I Acid Wash My Swimming Pool?

Although acid washing restores the swimming pool to a near-new state, it should never be used as a regular maintenance practice. This is because the chemicals used in acid washing can easily damage the pool and can also be dangerous to the person performing the acid wash.

Acid wash should only be considered when the swimming pool is evidently stained by mineral or organic deposits and the stains won’t go off after other methods of cleaning the pool have been engaged.

Acid washing is avoided because the process simply peels off a thin layer of the plaster to unveil a new fresh one that was formerly underneath. Experts advise one or two acid washes in five years.
