Replying to Sweaty feet and cleaning intuition liners

So I have intuition liners and they are so warm that my feet sweat even when it's super cold out. This causes my liners to get really wet and smell bad. Im looking into getting a boot dryer but what else can I do? Ive read that you can put anti perspirant spray on your feet... has anyone tried this and does it work? Also now thanks to my sweaty feet my liners smell. Is there anyway to clean or wash them to get the sweat smell out?
