Stubborn calcium scale and mineral stains don’t just make a pool look dirty—they can permanently discolor plaster and tile if left untreated. The PoolMaster Pumice Stone Pro Size is designed for tougher jobs, giving pool professionals and serious DIY pool owners a larger, more durable tool for removing heavy buildup from hard pool surfaces. This pro-size pumice stone delivers increased surface area and longer life compared to standard pumice stones, making it ideal for frequent use, large pools, and severe waterline scaling. When used properly on wet surfaces, it safely scrubs away calcium deposits, rust stains, and mineral buildup without adding chemicals or disrupting water balance. Professional-Grade Stain & Scale Removal The PoolMaster Pumice Stone Pro Size works through controlled abrasion. Kept wet, the stone softens slightly and glides across plaster, tile, gunite, and concrete, shaving off scale and stains that brushing alone can’t remove. The larger size allows faster coverage and less hand fatigue—especially useful for service techs handling multiple pools. This makes it an excellent solution for waterline tile, steps, spillways, benches, and other areas prone to visible calcium buildup. Why Calcium & Scale Buildup Matters Calcium scale traps dirt and algae, making pools harder to keep clean Mineral deposits can permanently stain plaster and tile Thick waterline buildup reduces curb appeal and pool value Chemical cleaners alone often fail to remove hardened scale Using a pro-size pumice stone allows targeted, chemical-free removal before buildup becomes a costly resurfacing issue.
