Tuff-Block - Nylon Brush Size:19" Excellent depth of etch controlThis Nylon Brush is best quality brush for this application. Nylon is flexible and supple enough to gently scrub carpets, yet has more "memory" than other fibers for a longer lasting brush. On brushes 14 in diameter and larger, the two outer rows are heavier to scrub, while the softer inner rows massage the dirt for a deeper cleaning action. Brushes under 14" have black bristles only. Larger brushes include both white and black bristles.
