Steady up Tremyfro. I haven't 'descended' on you with any rules or regs on hygiene. I have simply asked the question and responded to the ensuing discussion. If you think Milton will do the job then fine but don't be surprised if it taints the honey or indeed repulses the bees from using the frames thereafter. That's why I suggested the cleaning regimen that I did because from my professional experience it's a regimen that's most likely to achieve a satisfactory level of hygiene whilst avoiding a lot of the problems of managing plastics. That's for your benefit so you can continue to have your fun - safely!
