Don't know if anyone has tried this before? (I am sure I cannot be the first). I have a bunch of frames packed with pollen, some of which has some mold on it, some of it that seems so hard that I find it highly doubtful that the bees would make use of it or even be able to remove it. I really needed the use of the comb so I have tried "washing" the pollen out. I set my garden hose on jet and have begun spraying the frames for a few minutes and then letting them soak for a few hours and then repeating the process. It takes a while but seems to be working. The pollen softens up and then seems to turn mushy and washes out of the cells (to some degree). I am hoping that what is left will be easily removed by the bees if they have no use for it. There seems to be little damage to the comb and I am hopeful that it doesn't deter the bees from wanting to quickly make use of it. Anyone else have any experience with this?
