Acid wash pool costs

The cost to acid wash a pool is between $250 to $1,000. This procedure involves a professional draining the pool and then using an algae brush scrub to remove dirt, debris, and algae from any of the surfaces. The pool is acid washed when wet because it’s harder to remove algae once it’s dried. After the pool is ready, the pool is sprayed with a diluted acid mixture that won’t deteriorate the pool plaster. Once the mixture is applied, the pool is scrubbed and rinsed clean.

Post-wash, the professional removes all the wastewater. They’ll refill the pool and then ensure the water is chemically treated and ready for swimming.

Cost factors to acid wash a pool

Several factors can alter a pool acid wash cost.

Size

Large pools take longer to scrub and spray — and they generally require more acid wash to clean. If you’ve got a larger pool, expect to pay more for an acid wash treatment than someone with a smaller pool. A professional will average charge $0.40 to $0.60 per square foot.

Location

Prices change depending on where you live. In some areas, acid wash chemicals may have regulations that raise prices, or fewer professionals could offer the service. 

The location of your pool and how accessible that location is also factored into the cost. You may incur a travel fee for the service if you live out of town.

The stain severity

If your pool is badly stained and requires more acid to clean, it’ll take more time and materials to get the job done. Badly stained pools will have a higher cost based on logistics and time.

Labor cost to acid wash a pool

A professional breaks down most acid wash pool costs by square footage, usually charging $0.40 to $0.60 per square foot. If you live far away from the company you’re using, you may have to pay a travel fee. Badly stained pools could call for the professional to use more chemicals, resulting in a price bump. Likewise, if your pool is full of debris, the company might charge extra to cover the time spent getting the pool ready for the acid wash treatment.

DIY or hire a pro

Acid washing is a potentially dangerous treatment that requires a knowledgeable professional to get the job done correctly. If the acid isn’t diluted properly, it can eat away at your pool, wreck the plaster, or get on your skin — where it could cause a host of issues. The acid used is a potent chemical that shouldn’t be handled lightly. While DIY acid wash treatments are cheaper at around $30 to $50 for chemicals, a professional will know the proper dilution methods and come equipped with equipment that ensures a safe job.
