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.
Claims5
A brush for cleaning a corrugated surface having a plurality of at least substantially parallel grooves spaced apart a predetermined distance by a plurality of ridges;
- said brush comprising:
- an elongated body having a width at least as great as said distance;
- and
- a multiplicity of bristles carried by and extending downwardly from said body;
- said bristles being arranged in at least one row of bristles extending across said width with the bristles in said row having bottom ends complementary to the corrugated surface;
- the bristles in said row including a first set of bristles and a second set of bristles;
- the bristles in said first set having bottom ends positioned to engage the ridges of the corrugated surface, and having a first hardness;
- and the bristles in said second set being positioned to extend into the grooves of the corrugated surface to clean bottom surface portions of the grooves, and having a second hardness harder than said first hardness.
