Hard water stains

Struggling with crusty white scale, slimy algae, or mysterious pink biofilm on your pool tiles? The best pool tile cleaner depends on the problem: for hard water stains (chalky calcium buildup), use diluted muriatic acid or vinegar for mild cases. For green algae, a chlorinated tile gel works best, while enzyme-based cleaners tackle stubborn pink biofilm. Avoid wire brushes—they scratch tiles—and opt for a nylon brush or pumice stone (unglazed tiles only). Pool tile cleaning is smarter, not harder: balance your pool’s pH (7.4–7.6) to prevent scale, brush weekly, and toss a tennis ball in the skimmer to absorb oils. Skip gimmicky gadgets—simple tools and the right cleaner save time and sanity. For recurring stains or crumbling tiles, call a pro. Pro tip: Wipe tiles with a dryer sheet post-cleaning to repel future grime. Work smart, and enjoy a sparkling pool without the endless scrubbing!
