I read some of the posts in that thread and I'm quite surprised and also fascinated. I've always used plain water and paper towels to clean the vapor condensation off my windows. It's still cold enough here for there to be a lot of condensation in a small room where I
vape a lot. Gets the windows clean as a whistle if there are no other substances on them which is the case for me.
I do make my own
juice and only use PG, VG, water if required and flavorings.
Makes me wonder what is in other people's juices that makes the condensate behave so differently
