Real Transformations

From Stained to Spotless

Don't let ugly stains ruin your pool. See how our Stain Remover restores surfaces to their former glory.

100% Real Transformations. Zero AI. Just Real Results.

These aren't robot-generated pool dreams β€” just honest transformations from Aussie backyards like yours.

The Professional Method

Getting Results is Easy as 1-2-3

The treatment requires chlorine to be at 0–1ppm first. In winter you have a lot more leniency β€” pool usage is low, chlorine is naturally lower, and the process is far more forgiving than in the middle of summer. May to August is your prime window.

1
Chlorine Remover
Step 1: Pre-Treat
Chlorine Remover

High chlorine stops stain removers from working. In winter your chlorine is naturally lower β€” making treatment much easier. Use this to instantly drop levels to 0–1ppm if needed, rather than waiting weeks. Suitable for all pools.

Oxi Shock
Step 3: Finish
Oxi Shock

After the stains are lifted, your water might be cloudy. Oxi Shock burns off the residue and restores that Diamond Sparkle. Chlorine-free. Swim instantly.

The Science

Your Pool's Secret Weapon Against Stains

Our formula works smarter, not harder β€” lifting stains without damaging your pool or its chemistry.

Tackles All Stain Types β€” In & Out of the Pool

Dissolves oil stains, rust marks, mineral deposits, hard water stains, leaf marks, and algae shadows β€” not just in your pool but on driveways, fences, tiles, and paved areas around the home too.

Surface Safe β€” Pool, Yard & Home

Safe for all pool surfaces β€” concrete, pebblecrete, fibreglass, vinyl, quartzon, and tile. Also works on driveways, pavers, fences, and outdoor hard surfaces around the house.

Fast & Powerful Action

The formula chemically reacts with stains, breaking them down so you can easily brush them away without endless, harsh scrubbing.

Why Not Generic?

Specialist Formula vs. Generic Acid

You might see generic oxalic acid in hardware stores, but is it right for your pool? Here's why our purpose-built formula is the smarter, safer choice.

Water TechniX Stain Remover
  • Specialised blend β€” Oxalic and Citric acids designed to work synergistically in pool water
  • Broad-spectrum β€” targets rust, minerals and organic leaf stains in one application
  • Pool surface safe β€” manufactured and tested for all surfaces including vinyl and fibreglass
  • Proven performance β€” formulated for pool water chemistry for reliable, consistent results
Generic Hardware Store Acid
  • Single ingredient β€” raw oxalic acid only, may not be effective on all pool stain types
  • Unknown purity β€” not intended for pools, potential impact on water balance unknown
  • Risk of damage β€” using a non-specialist product risks harming vinyl liners or fibreglass gel coats
Step-by-Step Guide

A Stain-Free Pool in 6 Simple Steps

Follow our guide to get the best results and restore your pool's sparkle. It's easier than you think!

1
Lower Chlorine (Step 1)

Reduce chlorine to 0–1 ppm β€” this is the most critical step. In winter (May–August), your chlorine is naturally lower and the pool is less used, making this the ideal time to treat. Use Water TechniX Chlorine Remover to drop levels instantly if needed, rather than waiting days for it to fall naturally.

2
Adjust pH

Aim for a pH of 7.6 using pH Down or pH Up. This creates the optimal environment for the formula.

3
Apply Product

With the pump OFF, sprinkle the powder directly onto stains. For walls, use the 'sock trick' (see our pro tips below). Let it sit for a few hours.

4
Brush Gently

After 1–2 hours, gently scrub the treated areas with a suitable pool brush. The stains should lift away easily without harsh scrubbing.

5
Dosage

Spot treatment β€” apply a small amount to cover the stain. Widespread staining β€” approximately 1kg per 2 square metres for best results.

6
Rebalance & Prevent

Rebalance water to pH 7.2–7.6 and Chlorine 1.5–3.0ppm. Final step β€” use Oxi Shock to burn off organics and restore sparkle.

Pro Tips

Got Stains in Stubborn Places?

Try these pro tips for targeted stain removal in hard-to-reach spots.

Sock method

For Tricky Wall Stains

Pop the powder in a sock, scrub, then hang it over the spot. It slowly releases the formula right onto the stain overnight.

PVC pipe trick

For Hard-to-Reach Floor Stains

Use the PVC pipe trick β€” pour the powder straight through it for a precision drop. Bullseye, every time.

After Treatment

Pool Gone Cloudy After Treatment?

Don't worry, this is common. When pH drops too low as part of the treatment process, water clarity can be affected temporarily. Here's how to restore crystal-clear water.

1
Test & Balance

Use test strips to check pH and chlorine. Adjust pH to 7.2–7.6 and chlorine to 1–3 ppm.

2
Stabilise pH

Add an alkalinity increaser (buffer) to maintain stable pH levels and prevent future fluctuations.

3
Clarify Water

Use a clarifier for sand filters or a clarifier tablet for cartridge filters to bind fine particles.

4
Clean Filter

Clean your filter thoroughly during and after treatment to remove residue and captured particles.

5
Run Pump

Keep your pump running continuously. Your water should return to clear within a few days.

βœ“
Prevent Future Stains

Use a metal remover as a final measure to stop stains returning.

⚠️ A couple of things to know before you use it outside
