A question about "sticky vents", in this case it is about the deflectors/directors whatever they're called in the dash that are used to direct the air flow where you'd like. Mine (on my '97 e36) are very sticky, balky and difficult to move. I'm thinking I could spray some kind of lubricant on the pivot points but I want something that doesn't smell at all and is non-toxic.

Anyone have a good solution (pun intended)?
