I clean a lot of gutters for a living. I take a 5 gal. bucket with a hook on the handle, hang it off the gutter, scoop debris out by hand using good thick rubber gloves then blow the excess out with a stihl bg 55 leaf blower. Blow all leaders out as well. If they are clogged, take them apart. Fall cleanings are easy, we just blow everything out and let the landscapers take care of the rest. Of course we blow whatever mess we make away from the house.
