Anti Stain / Clear Stain – Pool Stain Remover & Surface Cleaner

Product Overview

Anti Stain / Clear Stain is a specialised pool chemical designed to remove unsightly stains and scum from pool surfaces. It functions as both a chelating agent for metal stain removal and a detergent-based surface cleaner for scum line and organic stain elimination.

The product is available in two primary formulations. Chelating agent formulations contain compounds such as EDTA (Ethylenediaminetetraacetic Acid), citric acid, ascorbic acid, or phosphonates that form stable, soluble complexes with metal ions (Fe²⁺, Fe³⁺, Mn²⁺, Cu²⁺) in pool water, preventing them from precipitating onto pool surfaces as stains. Detergent-based formulations (such as Anti Stain) include surfactant components for enhanced surface cleaning of scum lines and waterline organic deposits.

Anti Stain is available in 5-litre and 20-litre packs, making it suitable for both residential and commercial applications. It targets and eradicates unsightly buildup on pool surfaces and equipment filters, ensuring optimal functionality and aesthetics.

How It Works

Anti Stain works through two primary mechanisms depending on the formulation: chelation and detergent action.

Chelating Agent Mechanism (Clear Stain / Metal Stain Removal):

• Complex formation – Chelating agents form stable, soluble complexes with metal ions (Fe²⁺, Fe³⁺, Mn²⁺, Cu²⁺) in pool water
• Precipitation prevention – Metals are kept in solution, preventing them from precipitating onto pool surfaces as stains
• Stain dissolution – Existing metal stains are gradually dissolved and removed from surfaces
• Ongoing protection – Sequestrants provide continuous prevention of new stain formation

Detergent-Based Mechanism (Anti Stain / Surface Cleaning):

• Surfactant action – Detergent components break down and lift scum, oils, and organic deposits
• Emulsification – Organic matter is emulsified and suspended for filtration removal
• Surface cleaning – Scum lines and waterline deposits are effectively removed
• Equipment cleaning – Filters and pool equipment are cleaned of accumulated deposits

Important Note: Anti Stain is described as “a detergent to remove scum and stains from pool surfaces.”  It may not be suitable for use on marble surfaces.

Why It Matters

• Unsightly stainsdetract from pool appearance and create a negative impression. Metal stains (iron, manganese, copper) appear as brown, green, or black discolouration on pool surfaces. Anti Stain removes these stains, restoring the pool’s visual appeal.
• Scum linesand waterline deposits accumulate from body oils, sunscreen, cosmetics, and environmental contaminants. These deposits are unsightly and can harbour bacteria. Anti Stain effectively removes scum lines, keeping the pool looking clean and inviting.
• Equipment protectionis enhanced through stain and scale prevention. Mineral deposits can impair the efficiency of sand filters and other equipment.  Anti Stain helps maintain optimal equipment functionality.
• Metal stain preventionis essential for pools with source water high in iron or manganese (common in some Kenyan regions). Chelating agents keep metals in solution, preventing future staining.
• Surface protectionprevents permanent damage. Stains that are left untreated can become embedded in pool surfaces, requiring more aggressive and costly treatment.

Dosage & Application Guidance

Dosage requirements vary depending on manufacturer specifications, pool volume, contaminant load, water chemistry, and treatment objectives. Always follow product label instructions and professional water test results.

Based on the reference guide, typical guidance includes:

• Stain prevention: 250–500 mL per 10,000 litres monthly
• Active stain treatment: Brush stained areas, lower chlorine to near zero, apply sequestrant at higher dose as per product label
• Maintain low chlorine: During treatment to avoid chelate oxidation

Important: Most effective when chlorine is reduced (chelating agents are oxidised by high chlorine). May require repeat treatment for severe staining. Does not remove etched or physically damaged surface discolouration.

Metals (Iron, Copper, Manganese)	< 0.3 mg/L	Target for stain prevention

Step-by-Step Application Guide

For Stain Prevention:

Before Treatment:

1. Test pool water for metal content (iron, copper, manganese)
2. Test pH and chlorine levels
3. Calculate required dosage based on pool volume

During Treatment:

1. Measure the required volume of Anti Stain
2. With the pool pump running, add directly to the pool water
3. Allow circulation for even distribution

After Treatment:

1. Continue regular maintenance
2. Monitor metal levels periodically

For Active Stain Treatment:

Before Treatment:

1. Identify the type of stain (metal or organic)
2. Lower chlorine to near zero (stop chlorination 24–48 hours before treatment)
3. Brush stained areas to loosen surface deposits
4. Calculate required dosage based on pool volume
5. Gather required PPE: gloves, safety goggles

During Treatment:

1. Apply Anti Stain at the higher dose as per product label
2. For stubborn stains, apply directly to affected areas
3. Allow contact time (typically 24–48 hours)
4. Maintain low chlorine during treatment

After Treatment:

1. Brush stained areas again
