When to Schedule a Pool Acid Wash in Las Vegas Winters

Jan 11, 2026 | Pool Service

Even though it’s winter in Las Vegas, we still get the occasional pool that looks cloudy, stained, or just worn out. The colder months might seem like a break from pool care, but they’re actually one of the best times to take care of surfaces that have seen months of sun, debris, and changing water conditions. If your plaster looks dull or beat up, this is the right time to think about scheduling a pool acid wash in Las Vegas.

We understand that no one really wants to drain their pool in the middle of winter. But acting now can help prevent bigger problems when the warm weather returns. In this post, we’ll walk through what an acid wash is, why winter works better for the job, and how you’ll know if your pool’s ready for one.

What Is a Pool Acid Wash and Why It’s Done

An acid wash is all about giving your plaster surface a fresh start. It works by applying a special acid mixture to the exposed pool surface after the water is drained. The acid removes a very thin layer of plaster to get rid of heavy stains, embedded debris, or algae marks that won’t scrub off.

It’s especially helpful after your pool has sat for a while without circulation or has been through a period of green or cloudy water. Pool acid washing is typically used on concrete or plaster-lined pools. It doesn’t work for pools with fiberglass or vinyl liners, which may be damaged by strong chemicals.

Some common reasons we recommend acid washing include:

  • Tough algae stains that won’t scrub off after standard treatment
  • Leaf or debris buildup that left dark or uneven marks
  • Natural discoloration after heavy rain exposure
  • Surface buildup from minerals, chemicals, or imbalance over time

It might sound like a big step, but in many cases, acid washing can take the place of more expensive or time-consuming fixes, especially if the plaster is otherwise in good shape.

How Las Vegas Winters Create the Right Window

Winter in Las Vegas turns out to be one of the better seasons to carry out this kind of work. While the pool might not be in use much right now, the temperature and timing can actually make an acid wash more effective and easier to manage.

  • Cooler air and water temperatures help slow down chemical activity. That’s helpful when working with strong cleaning agents like acid and gives more control during application.
  • Winter months tend to see fewer pool activities, so draining the pool now is less disruptive to anyone’s routine.
  • Lower sunlight means algae don’t grow back as fast while the pool is drained and being worked on. That gives a cleaner slate once it’s refilled and chemical levels are balanced again.

Scheduling now also means you beat the rush that usually builds in early spring. When everyone starts thinking about cleaning and opening their pools, appointments get harder to snag.

Signs You Should Schedule an Acid Wash Now

There are some clear signs that point to acid washing as the next best step. If your pool has been through a rough season or just hasn’t looked the same lately, watch for these things:

  • Deep stains or blotchy marks in the plaster that don’t come off with brushing
  • A dark ring around the pool wall from water sitting at the same level for too long
  • The pool stayed green from algae for more than a few days, even after a cleanup
  • You’ve recently done a chemical treatment, but you’re still stuck with discoloration

Stains left after a green pool fix often need more than just chemicals. Acid washing can lift what’s left behind and help you actually see all the surfaces again.

Sometimes the shift in water clarity reveals older problems that just got worse over time. Winter gives you the time and space to take care of them without interfering with warmer-season plans. If your pool has any of these signs, it’s a good opportunity to address them now so they don’t become more stubborn in the future.

What to Expect During the Winter Acid Wash Process

If you’re thinking about booking an acid wash, it helps to know what’s involved. The process moves fairly quickly, and most of the time the pool is ready to refill in just a day or two.

  1. First, the pool gets completely drained until the surface is exposed
  2. Then an acid mixture (carefully prepared) is brushed onto the plaster to remove surface stains and buildup
  3. Each section is rinsed immediately after application to keep the surface safe and stop extra wear
  4. After everything is cleaned, a neutralizing solution is added to safely stop any leftover acid reactions
  5. Finally, the pool is refilled, and chemical balancing begins so it’s safe and stable again

The acid wash isn’t just about cosmetic fixes. It resets the surface and helps fresh water stay cleaner longer. That can set the tone for better water clarity once spring comes around. After the acid wash, your pool will be primed for the warmer months, with less chance of recurring stains or embedded algae.
