I wonder how/when your open mesh floors will come in contact with either acid or acidic fumes?I asked my mentor this last year he said if its the plastic coated mesh then yes if its just metal then it should be fine.
If in doubt remove the mesh floor.
Never used the stuff myselfI wonder how/when your open mesh floors will come in contact with either acid or acidic fumes?
Surely the only use for acetic acid is for fumigation ! . The boxes should be stacked in a bin liner , a flat dish of acid placed on top of frames of top box, then the bag sealed , as the fumes are heavier than air, the fumes will precipitate down through the boxes .
After a period of time, the boxes need ventilating before being put to use !
There is no need for the open mesh floors to be used during this operation !
I've never met a plutocratic beekeeper before .Never used the stuff myself
I blow torch the chambers and replace the frames for new every 2 years.
