I've used a lot of different products over the years including wd40, rubbing alcohol, goo gone, bug off, etc. This was the best thing I've ever used to remove tree sap. I used it to remove pine tree sap and it came off instantly. Didn't have to scrub or anything. It just wiped right off. Tarminator by Stoner. I got it from my local Napa. This is by no means an advertisement. Just a product I've used that works great.
