Pool Acid Wash in Camarillo

An acid wash strips a very thin layer off a plaster surface to remove stains, algae discoloration, and light scale, revealing cleaner plaster underneath. The pool is drained, a diluted acid solution is applied and rinsed, the acid is neutralized, and the pool is refilled.

When an acid wash helps

• Plaster that is structurally sound but stained or dull
• Algae staining after a pool turned green
• Light scale on plaster
• Preparing a pool for sale when plaster is still in fair shape

When it won’t help

• Plaster that is worn thin, rough, or showing the shell
• Delamination or hollow spots
• Deep metal stains, which may need different treatment
• Pools that have already been acid washed several times

Because each acid wash removes material, it shortens the remaining life of the plaster. Many pros suggest limiting how often it’s done.

Alternatives

• Chlorine wash or targeted stain treatment for organic stains
• Ascorbic or other mild acid treatments for some metal stains, sometimes without draining
• Bead blasting for scale on tile

Cost

Estimates only. Broad typical ranges based on published contractor and industry cost guides, not quotes and not our own data. Prices in coastal Southern California often run higher than national figures, and your pool’s size, condition, access, and finish choice can move the price a lot. Get written quotes.

Published guides commonly put a residential acid wash at a few hundred dollars up to around $1,000, plus the cost of refilling the pool. That’s far less than resurfacing, which is why it’s worth trying when the plaster is still sound.

Safety and draining rules

Acid washing involves strong chemicals and protective gear. Acid wash water must be neutralized and disposed of according to local rules, not sent into the street or storm drain. Hire a professional.

Before you hire

• Verify the contractor’s license at cslb.ca.gov and confirm it fits the work.
• Ask for proof of liability insurance and, if they have employees, workers’ compensation.
• Get a written contract that lists the finish, color, tile, coping, prep method, drain covers, water disposal, startup service, and payment schedule.
• California limits down payments on home improvement contracts, generally to 10% of the contract price or $1,000, whichever is less, and has separate rules for swimming pool contracts. CSLB explains the details.

Frequently asked questions

How often can a pool be acid washed?

Only occasionally, because each wash removes a layer of plaster. Many pros suggest limiting acid washes and resurfacing when plaster is thin.

Will an acid wash fix rough plaster?

Usually not. Rough, worn plaster typically needs resurfacing.

Is acid washing safe for pebble or quartz?

These finishes have different care needs. Ask your contractor before acid washing anything other than standard plaster.
