I went on an estimate today to look at a deck that needs to be pressure washed and stained. The deck was built almost a year ago, out of the entire deck only 3 steps have a heavy build up of sap on it. I know that the stain will not adhere to the sap, what can i use to remove the sap? Or should i just replace these boards?

Don't waste a minute on them other than replacing. You cannot stop the sap for more than a very short time.

Kind of a wild idea, but I too had one really sappy board as well as some knots oozing after I stained my deck.
I couldn't get the screws out so I tried another method that worked well surprisingly. I took a propane torch and lit the sap up. Let it bubble up scrap it off like four times. Then I took my grinder to it to remove any blackened areas.
Two coats of clear shellac and a coat of the Arbor coat semi and perfection.

I cant say it will last being the semi can't penetrate the wood through the shellac but we'll see. Lets face it the newer deck sealants and semi's don't penetrate that well anyhow.

Built a picnic table out of old seasoned wood. One of the seat boards started sapping. 3 years later it still seeps sap. Replace them.
