Pool Acid Washing in Gilbert, AZ

A pool acid wash takes a thin layer off the plaster to lift stains, algae marks and mineral buildup. It's a bigger job than a regular clean, and it starts with an empty pool. We do acid washing for pools in Gilbert and across the East Valley.

When a Pool Needs an Acid Wash

Most stains come off with brushing and balanced water. An acid wash is for the ones that won't. That might be dark marks left behind after a green pool, gray or brown mineral stains, or plaster that looks dull and blotchy all over.

Because an acid wash removes a little plaster each time, it isn't something to do often. Before you drain, we'll look at the stains and tell you whether a wash will help. Sometimes tile and calcium cleaning or a round of water balancing is enough.

Acid washing is meant for plaster. If your pool has a pebble or other finish, we'll look at it and talk through what makes sense for that surface.

Planning an Acid Wash Around the Arizona Heat

An empty pool sits in direct sun, and the hottest months are hard on bare plaster. That's why cooler times of year are usually the easier time to drain and wash.

Monsoon season brings another problem. Wind and dust storms can blow dirt and debris into a pool while it's empty. Planning around the weather keeps the fresh surface clean.

Refilling takes time too, since a pool holds a lot of water. Once it's full, the new water needs careful balancing so it stays clear and is easy on the fresh surface.

After the Acid Wash

A freshly washed pool looks brighter and cleaner. To keep it that way, the water needs steady care from the first week. Balanced water is easier on the plaster and slows new stains.

Weekly pool cleaning covers that, with brushing, testing and balancing every visit. Draining is also a good time to have the filter cleaned, since the system starts fresh with the new water. Ask about a filter cleaning when you book the wash.

FAQ

Frequently Asked Questions

Do you have to drain the pool for an acid wash?

Yes. The plaster has to be bare so it can be washed directly. If your stains are light, other cleaning may be enough, and we'll tell you before you drain.

How often should a pool be acid washed?

Not often. Each wash removes a little plaster, so it's best saved for stains that won't come off another way.

Will an acid wash take the calcium off my tile?

The tile line is a separate job. Our tile and calcium cleaning takes off the white crust at the waterline.

When can we swim again?

Once the pool is full and the new water is tested and balanced. We'll tell you when it's ready.
