Acid Wash & Draining

A deep clean a brush cannot do

Sometimes water chemistry alone cannot save a surface. Years of staining, stubborn algae, or a pool left to go green need a drain and acid wash: a controlled process that removes a thin layer of plaster to reveal the clean surface underneath. Done correctly, it can make a stained pool look years younger.

Draining and acid washing must be done carefully to protect the shell and follow LA drainage rules. We handle both safely.

What’s included

What acid washing covers

Safe draining

Drain the pool the right way, respecting hydrostatic pressure and local drainage rules.

Surface assessment

Confirm acid washing is the right call and the shell can take it.

Controlled acid wash

Evenly remove a thin layer of plaster to lift stains, algae and scale.

Stain treatment

Spot-treat stubborn metal or organic stains where needed.

Neutralize & clean up

Neutralize and dispose of wash water responsibly, leaving the site clean.

Refill & balance

Refill and balance the water so the freshly exposed surface stays healthy.

Our approach

Powerful, but not for every pool

Acid washing removes plaster, so it can only be done a limited number of times in a surface's life. We assess first and will tell you honestly if a wash will help or if resurfacing is the smarter move.

When it is the right call, we do it evenly and safely, and manage draining to protect both the shell and the surrounding ground.

Good to know

Acid Wash & Draining questions

Will an acid wash fix my green or stained pool?
Often yes. For heavy staining, algae or a neglected pool, a drain and acid wash removes buildup and a thin layer of plaster to reveal a clean surface, when the shell can take it.
How often can a pool be acid washed?
Only a limited number of times, since each wash removes a little plaster. If your surface is thin or worn, resurfacing is the better long-term option, which we will tell you honestly.
Is it safe to drain my pool?
Only when done correctly. Draining without accounting for ground water and hydrostatic pressure can damage a pool. We handle draining safely and to local rules.
