I have been using BG 3.0 AIOs and Pockets for about 8 months now an have always dried them. We have a gas dryer and made the mistake of drying them on high (70-80 minutes) for a couple of months and the tabs got rather curly, but still totally work. I had never had a gas dryer before, only electric and quite a fewthings got ruined - bathing suits, swim shorts, waterproof mattress pads, a comforter, until I figured it out. Oops!
Anyway, since then I just dry them on medium heat for 80 minutes after tyrning the AIOs inside out first. Lately, I have been hanging the covers, figuring they don't need that much drying, unless I am totally in a hurry. The heat does help to reseal the PUL so it's not all bad, right?
