PoolStyle 18" Professional Wall and Algae Brush with Stainless Steel Bristles

This is the PoolStyle 18 inch professional wall and algae brush, fitted with stainless steel bristles. It is the tool you reach for when a nylon brush has stopped making progress.

What stainless bristles are for

Nylon bristles sweep loose dirt. Stainless bristles cut. That difference matters with black algae, which roots into plaster and shrugs off a soft brush entirely, and with the stains and scale that build up on a hard surface over a season. An 18 inch head covers walls and floors quickly, and the professional build is meant for repeated use rather than occasional weekends.

Know your surface before you scrub

Stainless bristles belong on plaster, gunite and concrete. They are not suitable for a vinyl liner or a fiberglass shell, where they will leave scratches that cannot be undone. If you are unsure what your pool is finished with, use a nylon brush instead. This is guidance based on standard pool trade practice rather than a manufacturer restriction, but it is worth taking seriously, since liner damage is not repairable by brushing it the other way.

Getting the most out of it

Brush toward the main drain so the debris you loosen ends up where the circulation can collect it, and rinse the head with fresh water afterward, particularly after an algae treatment where the bristles have been sitting in heavily chlorinated water.
