The Secret weapon for rust stains

Is your beautiful pool plagued by ugly brown spots, rust streaks, or "tea-colored" discoloration? You aren't alone. Most pool owners scrub for hours, only to realize those stains aren't dirt—they are metal. And no amount of brushing will remove them. Pool Stain Treat by United Chemical is the "secret weapon" pool professionals use to restore surfaces without the hassle of draining the pool or performing a harsh acid wash.

Why Chlorine Can’t Fix This

When you shock a pool with metal content (iron), the oxidation actually causes the metals to "fall out" of the water and stain your plaster or liner. Pool Stain Treat reverses this process. Its proprietary blend uses strong chelating agents (including Oxalic Acid) to lift the iron metal off the surface and bind it up in the water.

The "Miracle" for Fiberglass Steps

Fiberglass pools and stairs are notorious for developing a yellow/brown rim or "tea stain" over time. Pool Stain Treat is widely regarded as the gold standard for restoring fiberglass to its original, bright white finish.
