no hand tool, just prespray the edges when pre spraying the whole room, clean the room and get as close as possible to the edge, then hands and knees with a terry towel and a bottle of M/S.
so far, (touch wood) not had a bad word from my courtesy calls, the wife does them and loves the feedback we get, and we call every job. custys seem to like it, maybe when ive been doing it as long as shaun i may have changed my mind but for now, it works well for us.
