pool wall cleaner

Even after scrubbing, your pool walls may still look gross because common mistakes sabotage your efforts. Pool wall cleaning isn’t just about chlorine—it kills bacteria but won’t remove algae or biofilm. The right brush matters: stainless steel for plaster, nylon for vinyl, and non-abrasive pads for fiberglass. Ignoring your filter? Debris will recirculate—backwash sand filters, soak cartridges, and inspect DE grids. Stains vary: green/brown is organic (use algaecide), purple/black is metal (citric acid), and white/gray is calcium (pumice stone). Balance water chemistry (pH 7.4–7.6, alkalinity 80–120 ppm) to prevent scaling or etching. For lazy perfection, a pool wall cleaner like the Dolphin Nautilus climbs walls and scrubs while you relax, but manual brushing is key for corners. Algae removal requires mechanical action—scrub first, then shock. Skip shortcuts: test water weekly, clean filters post-scrub, and attack the waterline (use Magic Erasers for fiberglass). If stains persist, check for metals or phosphates. Robots excel for maintenance, but manual scrubbing wins for precision. Bottom line: match tools to your pool type, balance chemistry, and clean proactively—or your walls will stay a science experiment.
