This cleaning question is interesting.
I was told the bees would clean the equipement up for themselves.
All my hive equipement was given to me - The equipment had been in storage and not used for a number of years - it was dusty, dirty, with signs of old moth damage. I didn't see anything active so all I did was wipe it off, scrap it out and put it out for the bees.
Do you think it needed more of a cleaning?
