Why customers choose Cera Garden

Powerful, all-natural stain removal

Natural Chemistry Extra Strength Stain Free is formulated with industrial-strength ascorbic acid to lift metal stains from pool liners and finishes without adding phosphates to your water. The formula is non-toxic and environmentally friendly, supporting safer, clearer pool water.

Why pool owners choose Stain Free

  • Tough on old set-in stains from metals, helping surfaces look closer to their original color.
  • Phosphate-free and compatible with all sanitizing systems, so you can maintain balance with your existing setup.
  • Pairs well with Natural Chemistry Metal Free for a confident two-step approach to stain fighting.
  • Packaged in a 12-pack, with each container weighing about 1.75 pounds, designed for ongoing care.

How to use

Recommended dose is 1 pound per 10,000 gallons of water. Balance pool water and lower chlorine to at least 1 ppm before application. Apply the product around the pool perimeter with the pump running, then brush the pool thoroughly. If stains persist, repeat the application.

Maintenance and best practices

  • Use as a weekly maintenance treatment to support a stain-free appearance.
  • Follow with proper filter care: add a pulp-based filter aid to cartridges or sand filters as directed; ensure DE filters are properly charged if used.
  • Keep to safe handling and storage guidelines to maintain product performance.

Packaging note: Includes 12 stain free containers per pack; container size is 1.75 pounds.
