Milt asks " Is it really possible to scrape the wax from Pierco (and other) plastic foundation and have the bees successfully redraw comb on it. " If the bees drew wax thick enough to cover the cells imprinted in the foundation then you'll need to chip the wax away to get the bees to draw it correctly the next time, revealing the 'imprint' in design you want them to follow (vs. their imprint left in the wax). Part of using plastic foundation is finding/scraping portions of Pierco/Ritecell/etc where the bees preferred drone cells or brace comb. Freezing for some is the easiest method to clean plastic. During the summer I'll use a power washer followed by a bath in 50-50 bleach/water on old frames. If you have possibility of disease you'll need attention in pressure-washing off 100% of the wax. You'll find wax/silk flake off easily and only take a few seconds per side. No worries on re-coating plastic with wax. Wax coating simply speeds things up for the bees but not 'necessary'. If you're using plastic foundation then you already know the difficulties getting the bees to draw vs. wax/waxed. More-so (difficulties) with unwaxed foundation. So you'll just have to stick to the rules -more- on drawing unwaxed foundation: ON a heavy flow, JUST above the brood nest, One or Two frames mixed in with other drawn frames, Sprayed lightly with syrup --- & then you'll have to visit the box every 3 or 4 days to add in more frames, scrape down imperfections, etc, to get the bees to draw exactly the way you want. There are other methods to draw (ie - on large hive & strong flow, entire box of undrawn & drag up 2 frames of brood & place just over the brood nest; feeding to simulate flow when warm enough to draw), etc. Once the frames of plastic are drawn they're superior in every way to wax foundation - or worse, Duragilt. The 'trick' is getting the stuff drawn correctly. Bees prefer wax. But then that's 'management', getting the bees to do something the beekeeper prefers... & BTW - For beginners & hobbyists, I would recommend using Duragilt. But for those whom would prefer to 'learn' about managing combs and prefer durable frames over the long term, plastic -is- your solution.
