Yeah, there's two kinds of pressure treated - for ground contact and not for ground contact. Both suck, IMO. I've been soaking the crap from HD and Lowes with this: I usually wait a month or two for the "lumber" to dry out a bit as this will help suck up the liquid goo. Ideally I would like to stand them up in a PVC pipe full of the stuff but haven't tried that yet. I'll probably not outlive the posts I've done but I tried.
