Pool Acid Wash in Arizona
When brushing and chemicals cannot fix the staining, a pool acid wash removes the top layer of plaster to reveal a fresh surface. We drain, acid wash, neutralize, and refill so your pool looks clean and bright again.
What Our Pool Acid Wash Service Includes
Our pool acid wash service covers the full process of draining the pool, applying the acid solution, scrubbing the walls and floor, neutralizing and rinsing, and refilling with fresh water. We serve pools across Mesa, Chandler, Gilbert, Tempe, Queen Creek, Paradise Valley, Scottsdale, Gold Canyon, and Phoenix.
Pool Drain-Down
We drain the pool to expose the plaster surface so we can work on it directly. We check the hydrostatic valve and the groundwater situation before draining, because the East Valley water table can push up on an empty pool if the valve is not working.
Acid Application
We apply the acid solution carefully to the walls and floor in sections, working from the deep end up. The acid dissolves the top layer of plaster along with the staining, calcium scale, and algae that have set into the surface.
Surface Scrubbing
We scrub the walls and floor with the acid solution to lift the staining and scale. We work in small sections so the acid does not sit too long in one spot, because over-application can etch the plaster and shorten its life.
Neutralize & Rinse
We neutralize the acid with a base solution and rinse the entire surface thoroughly before refilling. This stops the acid from continuing to work on the plaster and makes sure no residue is left behind when the pool is refilled.
Refill & Equipment Check
We refill the pool with fresh water, check the equipment, and start the system back up. We balance the chemistry from scratch, because fresh water has no chlorine, no stabilizer, and no balance until we set it up.
Chemistry Re-Balance
After the refill, we test and adjust the chlorine, pH, alkalinity, and stabilizer so the fresh water is safe and balanced. A freshly acid-washed pool needs a full chemistry setup, and we handle that as part of the service.
Products & Equipment We Use
We use professional-grade muriatic acid for the wash and a neutralizing base solution to stop the acid after the scrub. For the refill and chemistry setup, we use chlorine, pH adjusters, alkalinity increaser, and stabilizer from trusted suppliers like Hasa, BioGuard, and Leslie. These products hold up in the Arizona heat and keep your water balanced after the wash.
For equipment, we trust brands like Pentair, Hayward, and Jandy for pumps, filters, and cleaners. When we refill and restart the system, we check that the pump, filter, and cleaner are all running right so the fresh water circulates properly from the start.
How a Pool Acid Wash Visit Works
Every visit follows a clear process so you know what to expect.
We Drain the Pool
We drain the pool to expose the plaster, checking the hydrostatic valve and the groundwater situation first. The East Valley water table can push up on an empty pool, so we make sure the valve is working before we start.
We Acid Wash & Scrub
We apply the acid solution in sections and scrub the walls and floor to lift the staining, scale, and algae. We work in small sections so the acid does not sit too long in one spot and etch the plaster.
We Neutralize, Rinse & Refill
We neutralize the acid, rinse the surface thoroughly, refill the pool with fresh water, and balance the chemistry from scratch. We restart the equipment and confirm everything is running right before we leave.
Pool Filter Cleaning
After an acid wash, the filter is often full of the debris and residue that came off the plaster. Our pool filter cleaning service pulls the filter apart, soaks the cartridges or backwashes the sand, and puts everything back so water flows freely again. We check the pressure gauge before and after so you can see the difference.
For cartridge filters, we deep-clean the elements to remove oils and calcium that a simple rinse leaves behind. For sand and DE filters, we backwash and recharge the media so your filter catches fine debris again. A clean filter after an acid wash keeps the fresh water clear from the start.
Pool Salt Cell Cleaning
If your pool runs a salt system, the fresh water after an acid wash means the salt level is at zero. Our pool salt cell cleaning service removes the cell, soaks it in a mild acid solution to dissolve any calcium scale, and reinstalls it so your salt system works like it should. We check the chlorine output and the flow switch while we are at it.
If your salt pool has been losing chlorine even though the system is running, a scaled-up salt cell is usually the reason. We clean the cell, test the output, and let you know if the cell is nearing the end of its life so you can plan ahead.
Pool Equipment Installation
If the plaster is worn thin from years of acid washes or age, our pool equipment installation service can replace the pump, filter, or heater while the pool is empty. We install equipment from Pentair, Hayward, and Jandy, sized to your pool and plumbed in so it runs right from the start.
We also install new salt systems, automation, and cleaners. When the pool is empty for an acid wash, it is a good time to upgrade equipment because the plumbing is exposed and the work goes faster.
