Batavia MAXXBRUSH Heavy-Duty Wave Brush is suitable for dry cleaning of surfaces with, for example, algae or fungus. Ideal for terraces, paths and driveways. This brush delivers a light abrasive effect, similar to a metal brush and is therefore not recommended for soft surfaces (wood/natural stone). Made from a unique blend of nylon and metal particles for optimal results and long life. For use with the Batavia MAXXBRUSH.
