I happened across a guy on craigslist who had a couple of hundred supers for sale so I went to take a look and bought 21 shallow honey supers,5 Illinois,and 5 deeps with frames.They all looked like they had been assembled,painted,and the foundation was put in and then they were stacked in a barn/basement or someplace and left for a long time.They are all dusty and the foundation dont look so good but the boxes and frames look new,but really dirty.Whats the best method for cleaning up and sanitizing this type of equipment ? I am taking the old foundations out and throwing them in a solar wax melter and then after I clean everything I will rewire(if needed) and put in new foundation.
