Sundown Outdoor Group removes stubborn stains, scale, and discoloration with professional pool acid washes across Chapel Hill. We bring back the original surface color of your pool.

An acid wash strips stains and scale that regular cleaning cannot reach. Here are the specific acid wash jobs our team handles for Chapel Hill homeowners.
A full acid wash treats the entire pool floor and walls to remove stubborn stains that brushing and chemicals cannot touch. We apply, scrub, and neutralize the acid to bring back the original surface color of your Chapel Hill pool.
If only a few stains are setting into your plaster, we can spot treat those areas without draining the whole pool. We apply a controlled acid solution to the stain and neutralize it right after.
Black algae leaves dark stains embedded in your plaster after you kill it. An acid wash strips those stains out of the surface so your pool looks clean again, not just treated.
Hard water leaves white scale and rust colored mineral stains on your tile and plaster. We acid wash the affected surfaces to dissolve the scale and restore a smooth finish.
Over years of use, white plaster turns dull and yellowed from sunscreen, body oils, and metals. An acid wash strips that discoloration and brightens the surface so your Chapel Hill pool looks new again.
A full drain and acid wash is the deepest clean your pool surface can get. We drain the water, acid wash every inch, neutralize, and refill so your pool starts fresh with balanced chemistry.
Our team uses muriatic acid at the correct dilution for your surface type, whether you have white plaster, colored plaster, or pebble tec. We mix the acid to the right strength so it strips stains without etching your surface too deeply. We also use a neutralizing solution after the wash to bring your surface pH back to safe levels before we refill your Chapel Hill pool.
For spot treatments, we use acid gels and controlled application tools that let us target a single stain without draining the pool. We protect your tile, your fittings, and your equipment from acid contact during the wash. After the refill, we balance your chemistry and get your pool filter cleaning done so your freshly washed surface stays clean.
From surface assessment to a verified refill, here is what happens when you call us for a pool acid wash in Chapel Hill.
Our team arrives at your Chapel Hill home, inspects your pool surface, identifies the type and depth of the stains, and checks whether your pool needs a full drain or a spot treatment. We figure out exactly what is causing the discoloration before recommending any work. You get a clear explanation of what we find in plain language.
After the assessment, we send you a written quote that covers the acid wash, the neutralization, and the refill if your pool needs draining. You see the full scope before we touch anything, and you decide what happens next. No pressure, no surprise charges after the fact.
Once you approve the quote, we drain the pool if needed, apply the acid wash, scrub the surface, neutralize the acid, and refill your pool. We check the pH and alkalinity after the refill to make sure your water is safe to run. Your surface leaves our hands clean and bright.
Stains and scale that set into your plaster will not come out with regular cleaning. If you notice any of these signs, call us before the damage gets worse.
Every acid wash starts with a full surface assessment to confirm your plaster can handle the treatment and to identify what is causing the stains. We do not just pour acid and hope for the best, we mix the right dilution, work in sections, scrub the surface, and neutralize the acid before we refill. That way your Chapel Hill surface comes out bright and even without etching or damage.
If your stains are only in a few spots, we may recommend a spot treatment instead of a full drain and wash. Every job is different, so we give a free written quote after seeing your surface, no pressure. We also handle pool cleaning service and pool equipment repair if your pool needs more than an acid wash.
We assess your plaster thickness and condition before we start so the acid wash is safe for your surface and will not cause etching or damage.
We neutralize the acid and balance your water chemistry after the refill so your surface is safe to run and your equipment is protected.
We protect your tile, your fittings, and your equipment from acid contact during the wash so nothing gets damaged while we strip the stains.
Our team assesses your surface and sends a clear quote before any work begins. You decide what happens next, on your timeline.
