DUAL TRIM BRUSH
NYLON INNER TRIM - The Nylon Bristles offer a smooth and easy glide across the glass. These bristles also easily give up dirt so as you rinse it falls from the window instead of becoming trapped and leaving spots behind. Nylon bristles are also lighter when wet, balancing out the heavier Boar's Hair bristles.
BOAR'S HAIR OUTER TRIM - For extra aggressive scrubbing the Boar's Hair Bristles fit the bill. These natural fibers are stiff and trap dirt.
JETS or RINSE BAR
PENCIL JETS - Pencil jets give a powerful blast of water onto the glass to rinse dirt away after you scrub it up. They give you precision when working but to a limited area.
RINSE BAR - A rinse bar runs the full length of the brush block. Multiple jets along the bar stream water on the glass for more complete coverage.
