My boyfriend is a contractor and whenever he does any work with insulation, before he touches the stuff, he covers himself with baby powder because it adheres to the fiberglass.
My Chocolate was chased by a rogue dog and found her way into our attic. She was up there for three days, rooling around and makin g dough. Now that I have her out, he told me to take her and douse her w/ baby powder, then gently comb it out AGAINST the fur and then to do it again and again.
Then try and put some by her face so shell sneeze.
Also, some guys he used to work with had beards, and when they were done for the day, they'd rub their beards on grass, which has something in it that does the same thing.
Also, if you do use water, DO NOT use hot or cold water, it should be lukewarm to cool.
