On black plastic brood frames that wax moths got I just scrapped them with my hive tool and put them back on the hive with success however I am not sure with the white honey super plastic frames. I have a few used boxes of frames that got dirty from sitting around (dust & dirt stuck to the wax) and I don't know what to do. I can scrape them off the same way and apply a fresh coat of wax just like I did to the broad frames & I'm sure the bees will build back up on them. The question is will I end up with dirt in the wax since bees will build on top of it or will they fully clean it up? I don't want dirt in my honey down the road. There is no way I am going to get them looking new without going through extreme measures. I would just throw them out and buy wood frames for the honey supers where I can replace the wax foundation. That would be far faster then cleaning these things. Please help.
