Upgrade your pool and spa upkeep with the Poolmaster Extra Large Pro Pumice Stone. This oversized tool is designed to tackle stubborn mineral buildup with a natural, chemical-free approach, helping you refresh ceramic tile, grout, and concrete surfaces more efficiently.

What makes it effective

  • EXTRA LARGE PRO SIZE FOR FAST CLEANING: The oversized surface covers more area, speeding up stain removal on big jobs.
  • REMOVES CALCIUM AND HARD WATER STAINS: Targets mineral deposits, scale, and grime on tile, grout, and concrete surfaces.
  • SHAPE OR BREAK FOR CUSTOM USE: Use intact for broad areas or break into pieces to reach tight corners and detailed areas.
  • 100% NATURAL AND CHEMICALLY NEUTRAL: Made from natural pumice with no harsh additives; safe for pool water when used as directed.
  • FOR HARD SURFACES ONLY: Suitable for ceramic tile, grout, and concrete; avoid vinyl, fiberglass, porcelain, glass, or delicate surfaces.

How to use for best results

  • For large areas, glide the stone over the surface in a gentle, steady motion to lift mineral buildup.
  • For tight spots, break the stone into smaller pieces to reach grout lines and crevices.
  • Rinse surfaces after scrubbing and allow air to dry before use to maintain surface integrity.

Ideal use cases

  • Tile surfaces where mineral stains are visible around the waterline or in grout lines.
  • Grout cleaning to restore contrast and reduce grout discoloration.
  • Concrete pool surrounds and deck areas that show stubborn mineral deposits.

Safety and care

  • Designed for hard surfaces; avoid coated, vinyl, glass, or delicate materials to prevent scratching.
  • Natural pumice with chemical neutrality offers a gentle cleaning option when used as directed.
  • Store in a dry place and use with normal pool maintenance routines for best longevity.
