Protect your investment and keep your water sparkling with Spa Stain & Scale Free 500 mL, a multi-purpose liquid concentrate formulated to eliminate staining and prevent scale formation in hot tubs and spas. This professional-strength treatment controls calcium buildup and metal staining caused by iron, copper, and other dissolved minerals — without the use of phosphates or harsh acids.

Designed for ongoing protection, Spa Stain & Scale Free helps maintain clear water, smooth surfaces, and optimal equipment performance.

Is This Product Important for Salt Spas?

Yes — especially important for saltwater spas and hot tubs.

Salt systems generate chlorine through electrolysis, which can accelerate calcium scale formation on salt cells and heater elements. Scale buildup reduces efficiency, shortens equipment lifespan, and can lead to costly repairs. Spa Stain & Scale Free helps:

✔ Prevent scale on salt generator cells
✔ Protect heater elements and plumbing lines
✔ Reduce mineral deposits in high-calcium water
✔ Maintain optimal sanitizer production

While essential for salt spas, it is also highly recommended for:

• Hard water areas

• Fresh fills with high calcium levels

• Well water applications

• Any spa experiencing metal staining

Key Benefits

• Reduces calcium and mineral scale buildup

• Controls metal staining from iron and copper

• Phosphate-free and acid-free formula

• Compatible with all spa surfaces

• Safe with most sanitizing systems

• Helps extend equipment life

Do not use with biguanide systems.
Avoid adding at the same time as cationic polymer clarifiers, flocculants, or polyquat algaecides. Wait 24 hours between additions.

For best results, use in properly balanced spa water. If hardness exceeds 400 ppm, increase weekly maintenance dosage accordingly.

Instructions for Use

Initial Treatment (Fresh Fill)

• Add 60 mL per 1,000 litres of water when filling the spa.

• Run circulation pump for 1 hour after adding.

• Wait before adding disinfectant.

Weekly Maintenance

• Add 30 mL per 1,000 litres of water weekly.

• Ensure proper circulation for even distribution.
