I’ve used both Simple Green Pro HD (like $12 for a gallon of concentrate from the orange box) and Rockler Pitch and Resin Remover (I think $15). The Simple Green is enough cleaner to last forever, at least the way I use it. You can also reuse the Rockler stuff. I’ve reused the same bottle four times so far and it works just as well now as the first time.

I’ve heard that regular Simple Green can weaken the bond between carbide teeth and the steel blade, but I don’t remember the source or how reliable it was. That’s why I ended up with the purple stuff (the Pro HD) not the green stuff.

Either way, you soak the blade in some kind of flat-bottomed container and then brush off the crap. I use a $1 pack of copper/brass bristled brushes that I got from Harbor Freight. It gets all the gunk off. If something is stubborn, soak it longer or brush it harder.

I will say that it’s incredibly easy to cut yourself while trying to hold a blade to brush it, so wear some decent work gloves while handling them.

It’s kind of amazing how fast crap builds up on your blades when cutting soft and/or resin-y woods. I had to clean my blade twice during my workbench build from all the crap the spruce left on there.
