Pool Drain and Acid Wash
Pool Drain and Acid Wash Service in Northern Virginia
Potomac Pool Service provides professional pool drain and acid wash service throughout Northern Virginia for plaster pools with stubborn surface staining, scale, or discoloration. Service is priced at $1,350 and includes draining, surface treatment and rinsing, refilling, filtration restart, and water chemistry rebalancing.
Some staining and buildup won’t respond to brushing, chemicals, or a stronger filter cycle. This service helps remove stubborn surface staining, mineral deposits, and discoloration from suitable plaster finishes, restoring a pool that regular cleaning can no longer address.
This is a planned service rather than a seasonal one, so it can be scheduled whenever staining, discoloration, or buildup becomes a problem, not tied to spring or fall timing.
Family owned since 2003. 20+ years serving Northern Virginia, Maryland, and D.C. Hundreds of pools restored and maintained each season. Authorized LOOP-LOC safety cover dealer.
When Does a Pool Need an Acid Wash?
Regular brushing, vacuuming, and chemical balancing solve most pool problems, but some surface issues build up past the point where routine care can fix them:
- Mineral and calcium scaling. Hard fill water or chronically imbalanced calcium and pH levels can contribute to scaling on plaster and other pool surfaces over time, and buildup that resists normal cleaning gets worse the longer it sits.
- Residual organic or algae staining. Some staining can remain on plaster after the underlying algae problem has been treated. If standard cleaning methods can't remove the remaining discoloration, our team can assess whether an acid wash is appropriate.
- Aging plaster surfaces. Older plaster loses its smooth finish over time, becoming more porous and more prone to holding stains, discoloration, and rough texture.
- Persistent staining despite proper cleaning. If visible discoloration remains even after appropriate chemical treatment and cleaning, the surface itself, not the water, may be the issue.
Persistent staining can become more difficult to correct over time and deteriorated or heavily damaged plaster may ultimately require resurfacing rather than surface cleaning alone. If you’re not sure which category your pool falls into, we can take a look.
What Does Pool Acid Washing Include?
Pool Cover and Debris Removal: $525
A pool drain and acid wash service drains your pool completely, applies an acid treatment to help remove stains and buildup from the plaster surface, rinses the surface clean, refills the pool, restarts the filtration system, and rebalances your water chemistry.
Tasks included:
- Full drain of the pool
- Acid treatment application to the plaster surface
- Surface rinse and cleanup
- Refill with fresh water
- Filtration system restart
- Water chemistry testing and rebalancing
Need your spa serviced too? Our dedicated Spa Drain and Clean service provides a full spa drain, shell and jet cleaning, refill, and chemistry rebalancing for $405.
Pool Acid Wash Service
$1,350
Full-scale draining and acid treatment for pools dealing with stubborn staining, discoloration, or calcium buildup that regular cleaning can’t resolve.
Included:
- Complete pool drain
- Acid treatment of the plaster surface
- Surface rinse
- Refill and filtration restart
- Water chemistry rebalancing
If staining has gone beyond what an acid wash can fix, our Renovation Services team handles full resurfacing and plaster replacement.
Can Every Pool Be Acid Washed?
No, not every pool can be acid washed. Acid washing is primarily used on appropriate cementitious pool finishes, and the condition and type of surface should be evaluated first. Older, deteriorated, damaged, or specialty finishes may require another cleaning method or resurfacing instead.
Our technicians assess your surface before beginning work and will let you know if a different approach, or a referral to our Renovation Services team, is a better fit than an acid wash.
What Happens After an Acid Wash?
After the acid wash is complete, the pool is thoroughly rinsed and refilled. Once the water reaches the proper level, filtration can be restarted and the water chemistry tested and rebalanced. Your technician will explain any finish-specific aftercare before the pool returns to normal use.
Refilling takes time depending on your pool’s size and water source, and the water needs time to stabilize before chemistry is fully balanced and the pool is ready for regular use.
When Should You Schedule an Acid Wash?
This service isn’t tied to a specific season, but a few things are worth planning around:
- Outside peak swim season, if possible. Your pool will be out of use during the drain, wash, and refill process, so scheduling around a stretch you're not planning to swim minimizes disruption.
- Earlier is easier. Staining and buildup only get harder to remove the longer they sit, so scheduling once the issue becomes visible is generally better than waiting.
- Coordinate with other services. Some homeowners pair this service with a spring pool opening spring pool opening or as prep work before a planned renovation.
- Weather and site conditions matter. Pool acid wash service can be scheduled throughout much of the year, subject to weather, pool condition, and safe draining conditions. We'll walk you through what's appropriate for your specific pool and timing.

If staining, discoloration, or buildup have gone past what regular cleaning can fix, an acid wash can restore your pool’s surface. Request an assessment today and our team will evaluate your pool and get you scheduled.
When Should You Hire a Professional for Pool Draining?
- Staining that resists brushing and chemicals. If normal cleaning hasn't worked after repeated attempts, the surface likely needs professional assessment.
- Calcium scaling on tile or plaster. Visible white or gray buildup usually needs more than routine cleaning to remove safely.
- Preparing a pool for resurfacing. A drain and clean is often a starting point before larger renovation work.
- Pools that require complete draining. Emptying an inground pool needs to be planned carefully based on pool construction, site conditions, weather, and the condition of the surface. Professional assessment helps determine whether a full drain is appropriate and how to do it safely.
- Residual staining after algae treatment. If discoloration remains once the underlying algae issue is resolved, professional evaluation can determine the right next step.

Acid Washing vs. Weekly Pool Maintenance
| Pool Drain and Acid Wash | Weekly Pool Maintenance | |
|---|---|---|
| Type of service | One time surface restoration | Ongoing, scheduled through the season |
| What it covers | Draining, acid treatment, refilling, rebalancing | Continued cleaning, chemical balancing, equipment checks |
| Best for | Restoring a stained or discolored surface | Reducing the conditions that lead to staining and buildup |
An acid wash restores a pool surface that’s already fallen behind. Consistent weekly pool maintenance can reduce the conditions that contribute to staining, scale, and buildup, though not every stain is preventable through routine maintenance alone. If you’re weighing which service makes more sense for your situation, our Pool Service Packages bundle weekly care with seasonal service for year-round upkeep.

How do I know if my pool needs an acid wash?
If visible staining, mineral scale, or discoloration remains on the plaster surface despite proper cleaning and chemical treatment, an acid wash may be appropriate. Our technicians assess the surface of your pool first to confirm whether it should be acid washed.
Can every pool surface be acid washed?
No. Acid washing is primarily suited to appropriate cementitious plaster finishes. Older, deteriorated, damaged, or specialty finishes may need a different approach, including full resurfacing.
Will an acid wash remove every pool stain?
Not always. Results depend on the type of staining, the poll surface’s age and condition, and how long the staining has been present. Our team will assess your pool and let you know what to expect before starting.
How long before I can swim after an acid wash?
Not immediately. Refilling takes time depending on pool size and water source, and the water needs time to stabilize before chemistry is fully balanced and the pool is ready for regular use. Our technicians will give you an estimate for the appropriate time between service and swim-readiness.
What happens if surface damage is found after draining?
Our technicians will flag any additional issues found, such as cracks, plumbing problems, or surface damage beyond what an acid wash can address, and walk you through recommended next steps.
Do I need to be home for my pool drain and acid wash appointment in Northern Virginia?
It is not required that you be home during service, as long as we have property and pool access and any relevant details about your pool beforehand.
