As the beekeeping year starts to ebb away, there are always cleaning up jobs to be done. We try and re-use as many wooden frames as we can from our hives. Often these are replaced because the foundation is old or, more rarely, the colony has died or swarmed. Cleanliness is vital in beekeeping so we steam the wax out of the frames with a Thorne 'Easi-steam'. Then the frames get a boil in washing soda solution in an old Berco boiler rescued from the back of a garage.
This should mean they are sterile and ready to be rebuilt with fresh foundation for one of next year's new colonies.
