I use my shop vac to get most of the moisture out of my BCD bcd. I attach the hose to the exhaust outlet on the shop vac, remove the lower dump valve and the inflator hose from the BCD bcd, and hold the shop vac hose to the inflator hose hole in the BCD bcd. Once the shop vac is running, the BCDbcd inflates, and air and moisture come out the lower dump valve hole.
I occasionally insert a rag in the lower hole to soak up any moisture that collects there. Once I can't feel any moisture collecting in the bottom of the BCD bcd, I hang up the BCDbcd with the lower dump valve cover still removed, and let the BCDbcd air dry for a few days.
For my wetsuit, I rinse it out in the bath tub, and then put it into my washing machine, set the washer on spin dry, and start the spin cycle. After the spin cycle is done, I hang up the suit to finish drying.
