Hi all, I'm one of those who reported that the vaseline turned green and a few pins black. Well I know this sounds stupid, I was actually using Vaseline intensive skin care lotion. Ok before you laugh your *** off let me explain. Here where I live when people say vaseline, they refer to the skin care lotion. So when I read about vaseline working fine for condensation prevention, I was a bit skeptical but people assured me that it works. So I went off to use the wrong kinda vaseline. I have never heard or read of this Vaseline branded petroleum jelly and therefore used the wrong kind.
