I don’t know how may of you out there have bought the blade and bit pitch removers that the woodwork catologs advertize but hold on if you haven’t. I read somewhere a review on this stuff in one of the mags and remember seeing Simple Green mentioned. Well I tried it. Awesome. I bought a large concentrate bottle for about 8.00 from Lowes and after my wife discovered it I used what was left to de-pitch my blades. I poured neat concentrate in a flat pan and let the blade or bit soak for around 2-3 mins.(some were pretty nasty including heart pine deposits) A little action with an old toothbrush and pitch was gone. Highly recommended and cheaper that the small bottles that are touted as some kind of magic elixer. Let me know if you agree.
