Quick Answers

How quickly will I see results?

Results often show within 2 hours. For stubborn stains, leave overnight. With 4 bottles you can treat every stain in one session. Winter is ideal because lower chlorine helps the formula work faster.

Is it safe for fibreglass and vinyl?

Yes, when used correctly. For fibreglass and vinyl pools, apply using the sock method rather than direct contact to avoid any risk of bleaching. Fill a sock with the powder, scrub the stain, then hang it over the spot. This lets the formula work without direct surface contact.

Can I use this on driveways and fences?

Absolutely. The same formula works on rust marks, oil stains, and grime on concrete, pavers, and fences. Do a spot test on painted or natural stone surfaces first. Not recommended for marble or limestone.

Why treat stains in winter?

Winter is the perfect time. Chlorine levels are naturally lower so you skip the first step. Plus the pool isn't being used so you can let the treatment sit as long as needed. Fix stains now and you'll open to a spotless pool in spring.

The Stain Nightmare

You've scrubbed, shocked, and tried every pool shop remedy. Yet those ugly rust, leaf, and mineral stains keep staring back at you. Left untreated, they're slowly etching into your pool surface permanently.

Winter is when stains quietly get worse. Treat them now while the pool isn't being used.

Endless Scrubbing

Back-breaking brushing with zero lasting results. The stains always come back.

Wasted Money

Generic acids and pool shop remedies simply don't work on deeply embedded stains.

Permanent Damage

Left untreated, stains etch permanently into pool surfaces. A $3,000+ problem.

One Jar Isn't Enough

Stains spread across your pool, driveway, and fence. 4 bottles covers everywhere. Buy 3, Get 1 FREE.

The Science

How Stain Remover Eliminates Stains

Water TechniX Stain Remover uses a proprietary organic acid blend (Active: Oxalic and Citric Acid 980g/kg). It chemically reacts with rust, iron, and mineral deposits, breaking them down at the molecular level so they lift away without scrubbing.

1

Targeted Application

Sprinkle directly onto stains. The powder sits exactly where needed for maximum potency.

For fibreglass and vinyl pools: use the sock method to avoid direct contact with the surface. Fill a sock with powder, scrub the stain, then hang it over the spot.
2

Chemical Reaction

Organic acids dissolve rust, iron, and mineral bonds at the molecular level. No scrubbing needed.

3

Gentle Brush-Off

After 1 to 2 hours, stains lift away with a light brush. The surface underneath is unharmed.

4

Multi-Surface Protection

Safe for every pool surface and outdoor hard surface. One jar, everywhere you need it.

Step-by-Step Guide

Simple Steps to a Spotless Pool

With 4 bottles, you can treat pool, driveway, and fence in one session. Winter is the ideal time.

Application Instructions

1

Lower Chlorine Levels

Reduce chlorine to 0 to 1 ppm before application. The stain remover works best in low-chlorine water. Winter naturally keeps chlorine lower so you may already be close.

Apply the Product

For Concrete, Pebblecrete, Quartzon, and Tile:

With pump OFF, sprinkle powder directly onto stains. For wall stains, use the sock trick. Fill a sock with powder, scrub, then hang over the spot.

For Fibreglass and Vinyl Pools:

Use the sock method only. Direct application may cause bleaching on these surfaces. Fill a sock with powder, scrub the stained area, then hang the sock over the spot to let the formula work safely.

For Driveways, Fences and Outdoor Surfaces:

Sprinkle directly onto rust marks, oil stains, or grime. Add a little water to activate. Let sit, then rinse. Spot test on painted or natural stone first.

3

Let It Work, Then Brush and Rebalance

Allow 1 to 2 hours for light stains, or overnight for stubborn marks. Since the pool isn't being used in winter, you can let it sit as long as needed. Gently brush treated areas. Stains lift away easily. Rebalance water to pH 7.2 to 7.6 and chlorine 1.5 to 3.0 ppm. Use Oxi Shock to restore sparkle.

Important Safety Note

Wait until stains are fully treated and water chemistry is rebalanced before swimming. Always spot test on outdoor surfaces before full application. Not recommended for marble or limestone. For fibreglass and vinyl pools, use the sock method only.

Before re-entering the pool, ensure your water is balanced:

  • Chlorine: 1.5 to 3.0 ppm
  • pH: 7.2 to 7.6

Always read and follow the full product label instructions and safety precautions.
