Key Fit and Function Surface Cleaning Tool – Designed to remove calcium scale, rust stains, and mineral buildup For Hard Pool Surfaces Only – Safe for plaster, concrete, gunite, and pool tile when used correctly Chemical-Free Cleaning – Does not affect pool water balance or sanitizer levels Underwater Use Compatible – Can be used below the waterline on steps, benches, and tile Effective on Waterline Buildup – Helps restore appearance of stained pool surfaces Light-Pressure Application – Best results achieved on wet surfaces with gentle pressure Not for Vinyl or Fiberglass – Intended for hard surfaces only; not suitable for soft pool finishes Calcium scale, rust stains, and mineral buildup can quickly make an otherwise clean pool look neglected—especially along the waterline and on steps. The PoolMaster Pumice Stone offers a simple, chemical-free way to remove stubborn deposits from hard pool surfaces without draining water or adding harsh cleaners. Designed specifically for pool use, this natural pumice stone gently scrubs away calcium, rust, and mineral stains from plaster, concrete, tile, and gunite surfaces. When used correctly on wet surfaces, it effectively removes buildup while minimizing damage, making it a go-to tool for service pros and hands-on pool owners alike. Chemical-Free Calcium & Stain Removal Unlike acidic cleaners or abrasive chemicals, the PoolMaster Pumice Stone relies on controlled mechanical action. When kept wet, the stone softens and glides across hard surfaces, shaving off calcium scale and rust deposits without introducing unwanted chemicals into your water. This makes it especially useful for spot cleaning waterline tile, steps, benches, and spillways where buildup tends to collect and is difficult to remove with brushing alone. Why Calcium & Mineral Buildup Matters Calcium scale traps dirt and algae, making surfaces harder to keep clean Mineral deposits stain plaster and tile, reducing pool appearance Buildup along the waterline can become permanent if ignored Harsh chemicals can damage finishes or disrupt water chemistry Using a pumice stone allows you to address these issues directly and safely—without altering your pool’s balance.
