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. Lower chlorine from winter 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.

How soon before school holidays should I treat?

Treat at least one week before you plan to swim. That allows time for the product to work, for you to rebalance water chemistry, and for any cloudiness to clear. Most customers treat on a Friday and are swimming by the weekend.

Spring Opening Warning

Open Your Pool to Stains, Or Fix Them Before the Cover Comes Off

The cover is about to come off. What you find underneath determines whether your spring is spent swimming or scrubbing. Spring's higher UV and warmer water make stains set faster. What was cosmetic in August is permanent by November. One treatment now covers your pool, driveway, and outdoor areas at a fraction of what resurfacing costs.

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 with light brushing.

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 heavy 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. Spring water temperatures help the formula work at full strength.

Application Instructions

1

Lower Chlorine Levels

Reduce chlorine to 0 to 1 ppm before application. The stain remover works best in low-chlorine water. Chlorine is naturally lower after winter, so you may already be close.

2

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 in use yet, 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.
