I’m just about to do my first inspection of year 2. I was going to add my Queen excluder and a super but when I unpacked my super it looked like this. Is it ok to use or how do I clean it up?
That's fine - a little bit of waxmoth frazz which they'll clean up - I'd uncap the stores you have left in there before putting it back on though, they'll clean it all up then before refilling.
