FeaturedPool Blok Tile & Concrete Cleaner
The original Pool Blok Tile & Concrete Cleaner by United States Pumice Company is a trusted heavy-duty pool cleaning block (14.5 x 6.8 x 6.8 cm / 5 3/4" x 2 11/16" x 2 11/16") relied on by swimming pool service professionals for over 60 years. Specially engineered to quickly erase stubborn water and chemical rings, lime scale, rust marks, algae, and leaf stains from ceramic pool tile, grout, and concrete surfaces. Its unique floating design means no pool draining is required—if dropped, it floats directly to the water surface for easy retrieval. Chemically neutral and effective when wetted with pool water or mild acid, it removes severe mineral scale even where strong acid chemicals have failed. An indispensable maintenance tool in Aruba's high-mineral, sun-intense environment.
