For pine tree sap use a degreaser it'll come right off, just be careful not to get something that is going to damage the vinyl i.e. brake cleaner. Probably one of the best things I can think of is WD-40. I'm in the Army and have gotten tree sap on my uniforms and I spray a little WD-40 on it, let it sit awhile, then wash em, they come out clean and it hasn't screwed up my uniforms so I doubt it'll screw up your top. Try it on a test area first though to be sure (I like to use my buddy's TJ for testing products!). Hope this helps.
