Water TechniX Stain Remover – Pool & Spa Stain Treatment
Water TechniX Stain Remover is a powerful yet safe solution designed to eliminate a wide variety of stains in swimming pools and spas. This effective blend of oxalic and other organic acids targets leaf stains, rust, iron stains, and even stubborn algae stains left over from deep-rooted algae, all while protecting your pool surfaces.
What types of stains are addressed?
Water TechniX Stain Remover is designed to tackle a wide range of common pool stains, including:
-
Rust marks
-
Iron and metal stains
-
Salt or mineral stains and marks
-
Organic stains such as leaf and plant marks
-
Faint algae-related stains, including black spot shadows.
These stains are effectively broken down and lifted from your pool surfaces, helping to restore a clean and clear finish.
How does it work?
The formula uses a specialised blend of active ingredients to chemically react with stain particles. It breaks down and dissolves metals (like rust and iron) and organic materials (such as leaves and algae marks) without damaging your pool surfaces. This process loosens and fades the stain, in most cases making it much easier to remove without harsh scrubbing or abrasive methods.
How do I apply it?
For best results, we recommend preparing your pool water first. Here is the process in 6 simple steps:
-
Lower Chlorine: Reduce chlorine to 0-1 ppm. High chlorine neutralises the stain remover. For saltwater pools, turn the chlorinator cell off during treatment.
-
Adjust pH: Aim for a pH of 7.6 using pH Down or pH Up. This creates the optimal environment for the formula to dissolve tough stains.
-
Apply Product: With the pump OFF, sprinkle the powder directly onto the stains, do not pre-dissolve.
-
For Concrete / Pebble Crete / Quartzon / Glass Beads: Apply directly to the affected area.
-
For Tricky Wall Stains: Pop the powder in a skimmer sock, scrub, then hang it over the spot to slowly release the formula overnight. Or if within reach, using gloves hand apply the sock.
-
For Hard-to-Reach Floor Stains: Use the old PVC pipe trick—pour the powder straight through it for a precision drop.
-
Brush Gently: Leave for 1-2 hours. Regular brushing is recommended to remove the stain. It should lift away easily without harsh scrubbing.
-
Dosage: For spot treatments, just apply a small amount to cover the stain. For larger or widespread staining, use approximately 1kg per 2 square metres for best results.
-
Rebalance & Prevent: Once the stain is removed, turn the filter back on, super chlorinate, and rebalance your water. Aim for pH 7.2-7.6 and Chlorine 1.5-3.0ppm. Use a Metal Sequestrant (Metal Out) to prevent future stains. Do not swim until the water is clear and pH is balanced.
Note: Stubborn or older deep-set stains may require 2-3 repeat treatments for complete removal.
We recommend to trial in a less inconspicuous area to begin with, apply the product, let sit for 2 hours, scrub and assess, evaluate the performance then gauge your treatment plan accordingly.
Is it safe for surfaces?
Yes! Water TechniX Stain Remover is formulated to be gentle on a wide range of pool finishes, including:
-
Concrete / Pebblecrete / Glass Beads
-
Fibreglass, Vinyl, marble sheen and Spas (care should be taken) Never apply directly to the shell and allow to sit, best to contain within a skimmer sock, attach to your pool pole and rub the area, or if within reach, using gloves hand apply the sock
-
Quartzon
-
Tiled surfaces
It safely breaks down stains without damaging or etching your pool’s surface when used as directed.
Not Just for Pools: Works Around the Home!
Customers are discovering our formula works just as effectively on outdoor rust and mineral stains around the yard. It effortlessly lifts stains from:
-
Rusted fence posts (lifts oxidised rust from painted metal surfaces without damaging the finish)
-
Outdoor tiles, pavers, and concrete driveways (removes mineral deposits, grime, and organic stains from porous tiles and grout lines)
-
Garden water features and rusted tools
-
Boat Hulls
Outdoor Application Guide: This product is specifically designed and tested for pool surfaces. We've personally trialed it on outdoor concrete with great success, but it has not been tested on all indoor tiles, natural stone, or specialized surfaces. Always spot test in an inconspicuous area first and at your own discretion. We are not liable for surface damage outside of intended pool use.
Pathway Dosage: For pathway use, we recommend applying it as a diluted slurry for best results, using the least amount of product. The dosage rate is whatever is needed to cover the stain in its entirety.
What is the active ingredient?
The stain remover uses a proprietary blend of Oxalic Acid and Citric Acid, two proven ingredients that work together to dissolve and lift stubborn stains effectively and safely.
Is it biodegradable and eco-friendly? Yes! The acids combined in this blended product are all naturally occurring (citric from lemons and lime, and oxalic from plants when carbohydrates are oxidised naturally). This is an organic, completely biodegradable, non-hazardous, and non-poisonous substance.
🌱 Lawn & Plant Warning: While eco-friendly, it is an organic acid blend with a low pH. Like all these products, they need to be used sensibly. It would not necessarily be harmful to plants and animals, but we wouldn't recommend drenching them with it. Take caution around lawns, gardens, and plants, as concentrated runoff can cause temporary yellow patches (just like when dogs pee on the lawn from the acidity).

Important Note on Water Clarity (Cloudiness): It’s not uncommon for pool water to turn cloudy after using Water TechniX Stain Remover. Because this is a powerful acid blend, it lowers your pool's pH. Low pH inhibits the clarity of the water. To fix this post-treatment, it's important to raise the pH levels to 7.6ppm. Apply Alkalinity increaser (buffer) as required. Following the treatment, apply a floc if you have a sand filter, or clarifier if you have a cartridge filter. Manually vacuum to waste all remaining residue as required, keep the pump running continuously, and ensure to clean your filter.
