PENTAIR 18'' Metal Back White Blended Nylon and Stainless Steel Bristle Brush
Product Overview
Reinforced with an aluminum spine, this hybrid brush strips embedded black algae off plaster finishes without bending under heavy pressure.
Housed within a durable metal-backed frame, this 18-inch Pentair brush combines stiff stainless steel wire with flexible nylon bristles. Engineered strictly for plaster and gunite finishes, the dual-bristle pattern cuts through stubborn algae caps while sweeping dislodged particles into suspension. Unlike all-plastic utility brushes that flex and snap at the neck, the reinforced back gives you direct downforce against hard pool walls.

When To Use This
Pro Tip
When treating black algae, push the brush strictly in straight, forward strokes rather than scrubbing back and forth. Applying forward-only pressure cuts off the waxy protective algae cap without bending the steel bristles out of shape.
Common Questions & Instructions
Can I use this blended stainless steel and nylon brush on vinyl or fiberglass?
No. Even though nylon bristles are present, the stainless steel wire will tear vinyl liners and scratch fiberglass gel coats. The factory packaging explicitly warns: abrasive bristles, use on plaster pools only.
How often should this Pentair metal-back brush be replaced?
Most pool owners replace this brush every 2 to 3 years. Replace it sooner if you notice the stainless steel wire bristles bending flat, shedding into the water, or oxidizing.
What pole size does this brush attach to?
It attaches to any standard commercial or residential telescoping pole with an internal diameter of 1-1/4 inches using a standard push-button connection.
