Nice cold day to clean the wax off my heather super frames. For those that don't extract heather honey you need to cut the super out of the frame, leaving empty frames covered in wax etc, so to reuse you need to remove all this residual wax.
Bought a wonderful bit of kit a couple of years ago, an old Polish Potato Boiler. Takes a couple of hours to get to a boil (large volume of water). But cleaned 26 supers worth of frames of all residual wax in around 2 hours. My old method of scrape and scrape took around 10 days at 2 hours per day. Also cleans queen excluders in seconds....
