Say goodbye to rusty, scratchy stainless steel with our Silicon Carbide brush uses the same material found on street sweepers, but is pool-friendly and long-lasting. Thicker, larger bristles tackle rough surfaces like Pebble Tech and Diamond Brite, yet stay safe on new plaster pools. Floats instead of sinking, so even if bristles come loose, cleanup stays easy. Perfect for black algae without scratching, and built to outlast standard stainless-steel brushes.
