Great Bit & Blade cleaner
I wrote a lot about this in a thread some time ago. For the 30+ years I've been doing woodwork and home building, I've used Easy Off oven cleaner for my blades and bits.
Fast, clean, non toxic and for a can that lasts years it's about 3 bucks. Spary a little on, let it sit for about 2 minutes, brush with a toothbrush and the pitch (Even burnt on pitch) comes right off. Wipe with a rag and off you go. I'll never use anything else.....http://forum.carvewright.com/images/icons/icon14.gif
When I run out, I just add it to my wifes shopping list. Just a little bonus..LOL
