📋 How it works▾

Lo-Chlor Multi Stain Remover is a triple-action granular formula that removes metallic and organic stains from all pool and spa surfaces — handling iron, copper, manganese and organic deposits in a single treatment.

Metal staining is one of the most persistent pool problems in Australian conditions — particularly where bore water, old copper plumbing or garden runoff introduces dissolved metals that chlorine then oxidises into visible deposits. Unlike single-metal treatments, Multi Stain Remover handles all major stain types plus organic stains from leaves and tannins.

Lo-Chlor Multi Stain Remover details

  • Triple-action formula — removes metallic and organic stains simultaneously
  • Removes iron, copper and manganese staining
  • Also removes organic stains from leaves, algae and tannins
  • Safe for all pool surfaces — fibreglass, concrete, pebblecrete and vinyl
  • Does not affect water balance
  • Available in four sizes: 1kg, 2kg, 5kg and 20kg — choose based on pool size and stain severity

Choosing your size: The 1kg is right for treating a single staining incident on a standard residential pool. The 2kg suits larger pools or more significant staining. The 5kg is economical for ongoing use or pools with recurring metal staining on bore water. The 20kg drum is for commercial pools or service professionals.

To prevent staining recurring after treatment, follow up with Lo-Chlor Stain & Scale Defence weekly — it keeps dissolved metals in suspension before they can deposit again. For calcium scale specifically, Lo-Chlor Stain & Scale Attack is the dedicated two-part treatment. For the source of dissolved metals in the water, Lo-Chlor Metal Solution sequesters them before they deposit.

🧂Salt chlorinated▾
✓ Compatible — works with all salt systems
Fully compatible with salt chlorination systems. Apply with the pump running.
💧Traditional chlorine▾
✓ Compatible — works with all chlorine systems
Safe for all chlorine pool systems. Apply with the pump running and circulate for at least 2 hours.
🪨Mineral / magnesium▾
✓ Compatible — safe for mineral systems
Safe for mineral and magnesium pool systems. Does not interact with mineral sanitiser chemistry.
⚡Ionised / Nature2▾
✓ Compatible — safe for ionised systems
Fully compatible with ionised and Nature2 pool systems.
🏊Fibreglass▾
✓ Compatible — safe for fibreglass and vinyl
Multi Stain Remover is safe for fibreglass and vinyl liner pools at recommended doses. It does not bleach or etch surfaces. Ensure free chlorine is below 2 ppm before applying.
🧱Concrete / pebblecrete▾
✓ Compatible — works on all hard surfaces
Multi Stain Remover works effectively on concrete, pebblecrete, tiled and plaster surfaces. For organic staining (leaves, tannins) common in autumn, use the moderate dose and allow extended contact time.
💊 Dosage guide▾

Lower free chlorine to below 2 ppm before treating — high chlorine neutralises the active ingredients. Do not add more chlorine for 48 hours after application.

💧 Light surface staining
250 g
per 50,000 L
Distribute evenly around the pool. Brush stained surfaces after 4–6 hours. Run filter for 24 hours.
🟤 Moderate staining
500 g
per 50,000 L
Apply in the evening. Brush stained areas after 4 hours. Run filter continuously for 48 hours.
⬛ Heavy or old staining
1 kg
per 50,000 L
Maximum dose. Brush aggressively 4 hours after application. May require a second treatment after 48 hours.
🛡 Prevention follow-up
after removal
Weekly dosing keeps dissolved metals in suspension after treatment, preventing them from redepositing.
❓ FAQ▾
Do I need to lower my chlorine before using this?▾
Yes — this is important. High free chlorine oxidises the active ingredients before they reach the stain. Allow chlorine to drop below 2 ppm naturally (or shade the pool for a day) before applying. Don't add more chlorine for at least 48 hours after treatment.
My staining came back. What's causing it?▾
Recurring staining means dissolved metals are continuously entering your pool — typically from bore water, corroding fittings, or a copper-based algaecide used at low pH. Treat the source: Metal Solution sequesters dissolved metals before they deposit, and Stain & Scale Defence added weekly keeps them in suspension long-term.
What colour staining indicates what metal?▾
Brown or rust-red staining = iron. Blue-green staining = copper (often from plumbing or copper-based algaecides at low pH). Dark brown or black staining that doesn't brush off = manganese (common in bore water areas). Yellow or green staining that brushes off = likely algae or organic matter rather than metal.
Can I use this on a pool with a vinyl liner?▾
Yes — Multi Stain Remover is safe for vinyl liner pools at recommended doses. The granular formula dissolves evenly and does not bleach or damage vinyl. Ensure chlorine is below 2 ppm and brush gently — vinyl liners don't need aggressive scrubbing.
Which size should I buy?▾
For a first treatment on a standard residential pool with moderate staining, the 1kg is sufficient. If you have heavy staining or a large pool, the 2kg ensures you have enough for a full dose plus a follow-up. If metal staining is an ongoing issue (bore water supply or old plumbing), the 5kg is better value for repeat treatments.
