recently ive done a few of these and its bleedin hard work. im using a 10 inch swivel apllicator on a long trad pole or close up from the top of my ladder.
im now thinking i might get an applicator and bend the tube part into a sort of "C " SHAPE ,the shape of a gutter then put the sleeve back on . this may then slide along under the gutter without allowing the scrub to slip off at the sides . the gutter scrubbing game is good money
slipping off seems to be constantly in my mind ! im awake at the crack of dawn with painful ankles
