Before You Start an Acid Wash Don’t Make These Mistakes!

Show Notes

Draining a pool sounds simple until the plaster starts chipping, the customer expects miracles, or someone asks the one question that never goes away: “Will my pool pop out?” We break down the real-world judgment calls behind pool drains, acid washes, and chlorine washes, with a focus on timing, surface risk, and clear customer communication.

We talk about why the off-season is the sweet spot for a drain and clean, and why high air temps and direct sun can turn a routine job into cracked plaster, flaking steps, and permanent damage. You’ll hear how we think about full drains versus partial drains for high cyanuric acid (CYA), plus the situations where an acid wash is the wrong answer because the surface already has chips or cracks.

From there, we compare acid wash vs chlorine wash for pool stain removal, including when a chlorine wash is the better choice for organic staining, algae, and black algae. We also cover jobsite safety and chemistry: why chlorine and muriatic acid must never mix, how thorough rinsing protects you, and why straight liquid chlorine can leave caustic residue that can wreck a filter. Finally, we share a practical business lens: when these labor-heavy jobs make sense, and when to pass unless it leads to ongoing pool service.

If you want the acid wash waiver, email David@Swimmingpoollearning.com, then subscribe, share the episode with a pool pro, and leave a review so more techs can avoid expensive drain-day mistakes.

We walk through how to time a pool drain, acid wash, or chlorine wash so you do not damage plaster, trigger cracks, or create a headache you cannot undo. We also talk about setting expectations, choosing the right wash for the stain, and protecting your business from avoidable risk.
