Thanks for your input Michael. I've always heard that every 4-5 years, it's a good thing to switch out foundation/racks because the wax gets hard and the Q prefers to lay in fresher wax. This is the first time in a while I had noticed it. While I have switched out some over time, I never switch it all at the same time. Just a rack or two here and there. It's always been easy with wax foundation...just cut, clean grooves and replace. This is the first time to do this with the plastic foundation. I'm thinking this may be a good excuse to get a new turkey fryer pot and use the old pot for the plastic foundation. A win-win situation! I get a new pot, this time with a pour spout and the bees get some good clean foundation!
