Abstract
A brush for cleaning corrugated surfaces has a multiplicity of bristles extending across the width of an elongated body. The bottom ends of the bristles form a virtual surface complementary to the corrugated surface. The bristles include a first set of bristles positioned to engage the ridges of the corrugated surface and a second set of bristles positioned to extend into the grooves of the corrugated surface. The first set of bristles have a first hardness, and the second set of bristles have a second hardness harder than the first hardness. This provides greater cleaning action in the hard to clean bottom surface portions of the grooves.
