Anyone have an effective method for dealing with sap on pressure treated pine? Our first step of course is to try and let new wood age and dry a few months before we stain it, but sometimes I still run into issues. We use penetrating oil stains so I've even seen it come up on 20 year old decks. I've tried the turpentine on a rag but when the sap gets pushed to the surface of the wood it crystallizes in the sun to that white color. Right now I just scrape off what we can with a putty knife and lightly sand and then rag on some extra stain. If the sap vein is large though it just bleeds out more later on.
Thankfully it is a rare occurrence but can be a nuisance and trigger customer callbacks which I prefer to avoid.
