Personally, Id get my hands on some bamboo fleece and make some the same size to replace the microfibre boosters. (snaps australia has a special on bamboo fleece ATM - 2m for $30 plus postage)

You could get some microfleece and make like a (pillow) slip to pop the booster in so you dont have to touch it..one layer should be fine and maybe get some gloves when you touching it
