5 Tips for Removing Algae From Pool Walls Without Damage

Use a nylon brush A nylon brush is the safest tool for scrubbing pool walls. Wire brushes and stiff bristles scratch plaster, chip fiberglass, and tear vinyl liners.

Apply a mild algaecide Pair the nylon brush with a gentle algaecide. Harsh chemicals like bleach can damage pool surfaces.

Try a pumice stone for stubborn spots For tough algae, use a pumice stone designed for pool tiles while the surface is wet. Rub gently and avoid steel wool or pressure washers.

Prevent algae with regular maintenance Keep chlorine and pH levels balanced, and brush the pool weekly. Prevention is more effective than removal.

Be patient Scrubbing aggressively damages the pool. Soft tools and consistent effort work better than harsh methods.
