What is acid washing?

When pools have been poorly maintained or have had stagnant water in the past, phosphates from algae, dirt, chlorine, and sediments from hard water can build up over time and become embedded in your pool’s finish. In this case, acid washing is often necessary. Acid washing effectively removes unsightly stains from sediment buildup and hard water in your pool’s finish. A thin layer of your pool’s plaster or PebbleTec is removed in the process to reveal your pool’s original pristine glow.

We recommend acid washing your pool just once every 3-5 years, as frequently acid washing your swimming pool will expedite the need to resurface.

Does my pool need an acid wash?

If your pool needs an acid wash, your first clue will be in its appearance. Murky or dark water is the most common sign your pool needs an acid wash. Also, check your calendar. If your pool has been sitting six months without maintenance, it could be a good indication of buildup – consequently, you may need an acid wash.

How safe is acid washing?

Acid washing involves the use of chemicals, namely hydrochloric acid (also called muriatic acid) mixed with water. Hydrochloric acid has corrosive properties and could cause severe damage should it be inhaled or come into contact with your skin, eyes, or internal organs. Because it is quite risky to work with, it’s best to contact professionals who have the necessary safety equipment and who acid wash for various types of pools regularly.

Understanding the importance of getting your pool acid washed/polished by pool professionals

When it comes to the surface of your pool, you should be trusting professionals to acid/polish wash it. Swimming pool surfaces can fade, chip, and wear down over the years. You may even consider a remodel when it’s not necessary. 

Fortunately, Emerald Pools and Spas can asses the damage and will advise you on a plan of action. This consultation will typically include an assessment of your pool’s surface and an acid wash recommendation.

The process of acid washing begins with Emerald Pools and Spas draining your swimming pool and prepping the surface for the acid wash. A mixture of acid/water is created and applied to the pool walls and floor. Emerald Pools will apply the mixture evenly over the surface to prevent streaking and imperfections. During this process, a chemical reaction occurs which removes a thin layer of the surface as well as a thin layer of buildup that has accumulated over the years. 

After the mixture is applied, it is then pumped out of the pool to ensure only clean water is filling your swimming pool. Once this stage is complete, we will begin a proper start-up by adding the necessary chemicals to ensure proper chemistry. Upon completion,  we advise that you wait at least 3 hours before using your swimming pool.

Acid Washing Frequently Asked Questions

Can my pool be acid washed at any time of the year?

Due to cracking, we do not recommend acid washing a plaster pool when the temperature outside is above 80 degrees.  If you have a PebbleTec pool, we recommend that your acid wash can be performed at any time of the year as the surface is very strong. 

Does acid washing make my pool perfect again?

There are a lot of factors involved. Most of our acid washes make pools look new again. However, we have seen many instances where there can be a salt staining at the bottom of the pool which will prevent a pool from being acid washed. Our certified technicians will notify you in the event of a pool having difficulties being acid washed to perfection. 

Does an acid wash remove that white line around my tile?

NO, acid washing will not remove the calcium carbonate line around your pool tile. Arizona’s water is so hard that the line gets too thick and will need to be professionally cleaned with a tile blasting machine. Emerald Pools does offer this service. 

Can my pool be acid washed frequently?

The acid wash removes a thin layer of your surface. We only recommend getting your pool acid washed twice before having to resurface. 

How long does an acid wash take?

From start to finish, on average, 4 days from the time we drain the pool, acid wash, then start up with fresh chemicals. 

Can I watch Emerald Pools acid wash my pool?

Absolutely! From the inside of your house. Due to safety concerns from the vapors of the chemicals, we will ask you to watch from the comfort of the inside of your home. Our industry certified technicians will be gas-masked the entire time to make sure we are safe on our end!
