A scrubber for rain gutters with a scrubbing pad having a profile complementary to the profile of the outside side face of the gutter. The scrubbing pad is formed of a open cell natural or synthetic sponge and is attached to a substantially flat backing plate and makes substantially 100% surface contact with the outside side face of the rain gutter. The scrubbing pad overlaps a flange at the top of the outside side face of the gutter and overlaps a bottom of the rain gutter at the bottom of the outside side face. The scrubber is guided by the scrubbing pad along the rain gutter in a straight line by the overlapping portions of the scrubbing pad as the scrubber is moved back and forth along the rain gutter. |
