Natural Chemistry 14235NCM Spa Stain & Scale Control – 32 oz
Part # 14235NCM — a spa-safe stain and scale treatment designed to protect spa surfaces, equipment and salt system cells from mineral buildup and metal staining.
Key Features
- Reduces calcium and mineral scale accumulation on surfaces and equipment.
- Controls metal staining from iron, copper and other metals in spa water.
- Phosphate-free and acid-free formulation to avoid interfering with sanitizer systems.
- Compatible with spas, salt systems and most sanitizing technologies (excluding biguanide systems).
Typical Applications
Used in spas and hot tubs when surfaces show signs of white scale, metallic stains or when a salt system cell is developing reduced performance due to scale buildup.
Usage & Compatibility Notes
Ensure spa water is balanced (pH, alkalinity, sanitizer and calcium hardness) before use. For initial treatment, dose approximately 8 oz per 200 gallons. For maintenance, about 1 oz per 200 gallons. If hardness exceeds 400 ppm, double the maintenance dose.
Why Choose This Treatment?
This specialized formula helps prevent and remove stains and scale without using harsh acids or phosphates, supporting spa longevity and clean water performance.
Maintenance Tips
- Inspect spa surfaces, heater shells and salt cell plates yearly for scale or stains.
- During spa servicing or calcium/hardness changes, reapply the product to maintain protection.
- Avoid mixing with biguanide-based sanitizer systems.
- Keep the product stored in a cool, dry space and keep the container tightly sealed.
