To remove pitch buildup on blades, mix a 50/50 ratio of chainsaw bar chain oil and diesel fuel in a spray bottle and spray onto blade every minute or so. I have heard stories of using an old car windshield cleaner pump to deliver the solution to the blade. It works very well and I have no pitch remaining on the blade.
