Chemical Wash and MicroGlass in Yuma
A chemical wash lifts stains and scale off your pool's surface while taking off less plaster than an acid wash. MicroGlass is then sprayed onto the clean, dry surface, where it's designed to soak in and harden the top layer so future stains and scale are easier to clean.
What is Chemical Wash & MicroGlass and When Do You Need It
Yuma's hard water is tough on pool surfaces. Every season of evaporation leaves calcium and minerals behind, and over a few years plaster, quartz and pebble finishes pick up scale, stains, rough spots and a chalky look that brushing during weekly service won't remove.
A chemical wash is how we clean that off while keeping more of your plaster. It's done with the pool drained, like an acid wash, but it's gentler: it lifts stains and scale while removing less of the surface. That makes it the better first choice when the staining hasn't gone deep. When it has, an acid wash is the right call, and we'll tell you so.
MicroGlass is the step that protects the clean surface. It's a water-based treatment we spray onto the surface once it's dry. Its maker says it soaks in rather than sitting on top like a paint or sealer, and turns the soft particles in the surface into a harder, glass-like layer. They report less discoloration, craze cracking, etching and plaster dust, and stains and scale that are easier to clean afterward.
MicroGlass is made for white plaster, quartz and pebble finishes, not for vinyl, fiberglass or painted pools. And no wash or treatment can save a finish that's failing. Plaster that's cracked, flaking or coming loose needs repair or a replaster first, and we'll tell you that on the assessment rather than sell you a wash.
Our Chemical Wash & MicroGlass Process
It starts with an on-site look. We check the finish, how deep the stains and scale go, and whether any cracks or loose plaster need repair first. Then we tell you which job fits: a chemical wash on its own, a chemical wash followed by MicroGlass, or an acid wash if the staining is too deep for anything gentler.
On the day of the job we drain the pool, with the refill planned in the same sequence so the surface isn't left sitting empty in the heat. We apply the chemical wash in sections, then neutralize the surface and pressure-rinse it clean.
If you're adding MicroGlass, it goes on once the surface is completely dry: at least two fine-mist coats, applied the way its maker specifies. In warm weather it dries within a few hours. It can't go on at 44°F or colder, so in winter we schedule around cold snaps.
Then we refill the pool, balance the start-up chemistry and walk you through how to keep the surface clean. Balanced water protects a pool surface more than anything else, and our weekly service plans keep it balanced.
Pricing for Chemical Wash & MicroGlass
Published pricing for the chemical wash and MicroGlass is coming soon. What moves the price is the size of the pool, the finish (plaster, quartz or pebble), how much stain and scale there is, and whether you want the chemical wash on its own or followed by MicroGlass.
We don't quote it sight unseen. You get a written quote after the on-site look, before anything is drained, and you approve the price before we start. Water to refill the pool is separate and depends on your water rates. We can estimate it for you in the quote.

Why Choose Green Valley for Chemical Wash & MicroGlass
Our repair technicians completed chemical wash and MicroGlass application training in October 2026. Most of this job is the prep. A surface that isn't fully neutralized, rinsed and dry won't take the treatment the way it should, and MicroGlass's maker warns that skipping the neutralizing step leads to poor results and a whitened surface.
We're also honest about what your pool needs. If a chemical wash alone will do the job, we'll say so, and adding MicroGlass is your call. If the staining is too deep for a gentle wash, we'll tell you an acid wash is the right call. And if the plaster is near the end of its life, we'll say that too, because no wash or treatment brings back a failing finish.
Our technicians are CPO certified, and Green Valley has been serving Yuma since 1970. We hold Arizona ROC license #344581, Class CR-6, and we're bonded and insured.
Frequently Asked Questions
How is a chemical wash different from an acid wash?
Both are done with the pool drained. An acid wash removes a thin layer of plaster to take deep stains and scale with it. A chemical wash is gentler: it lifts stains and scale while removing less of the surface, so more of your plaster stays in place. We recommend it first when the staining isn't deep, and we'll tell you on the assessment if your pool needs the acid wash instead.
What does MicroGlass actually do?
Its maker describes it as a water-based treatment that soaks into a plaster, quartz or pebble surface and turns the soft particles in it into a harder, glass-like layer, rather than sitting on top like a paint or sealer. They say it reduces discoloration, craze cracking, etching and plaster dust, and makes future stains and scale easier to clean.
How long does MicroGlass last?
Its maker reports surfaces lasting longer with it but offers no specific guarantee on how much longer, and we won't promise a number either. What we can tell you is that water chemistry decides how long any pool surface lasts. Keep the water balanced and a treated surface has its best chance of staying clean.
Does the pool have to be drained?
Yes. The chemical wash and MicroGlass are both done with the pool drained, and MicroGlass goes on only once the surface is completely dry. We plan the drain and the refill as one sequence so the surface isn't left sitting empty in the heat.
Will MicroGlass work on my pebble or quartz finish?
Yes. MicroGlass is made for white plaster, quartz and pebble finishes. It isn't made for vinyl, fiberglass or painted pools, and we'll tell you on the assessment if your surface isn't a fit.
How soon can we swim afterward?
Once the pool is refilled and the start-up chemistry is balanced. Most pools are ready within a day or two of refilling, and we confirm the chemistry is in a safe range before we leave.
