I have a rack that holds 10 frames two wide 5 down i made of 2"x3"wood. I scrape of the bulk of the wax being sure not to actually scrape the foundation. then turn the hot water on to my presure washer. I spray off the one side of the ten then flip and do the other although I have never timed it and I do bunches at a time. I would say maybe 10 minuets to do 10 frames. once prepedTen bears, how long does it take to pressure wash a frame - seconds or minutes? I am thinking of doing this.
