10 inch swivel scrubber with a microtiger sleevee, fitted onto a Harris pole ,dip scrubber in bucket of normal window mix
if i want to buff up the gutter extra i drape a scrim over the scrubber
(i have been thinking of curving the bar,or at least making it V shaped , of a 10inch swivel scrubber so that it slides nicely around the shape of a gutter without slipping off as i wipe the gutter itself )
