This is one of the reasons that I don't use any hard chemical treatments, I want to know the wax is clean for making lotions, lip balms, candles, etc. As such, I don't worry about moving frames around, since I only use organic treatments, and they don't leave anything long-lasting in the wax. But I know with varroa being so new in your country, you don't have a lot of different products for treating varroa, so it may be more difficult to find options that don't leave long term contaminants in your wax. I do cycle out very old, very dark brood combs, just to be on the safe side for anything environmental the bees may have gotten into, but I don't usually use that wax for crafting or honey anyway. That's mostly just a bee health thing.
