After disinfecting your counterlungs, there is often a pool of water left behind. Here is a tip for drying the inside of the counterlungs.
Take a rectangular piece of chamois material and cut it like the pattern in the picture. You will end up with a really long strip of absorbent fabric. Now you can slip the chamois inside the countering and leave a tail hanging out the end. Hang it up overnight and the chamois will absorb all the remaining water.
