I was reading the other day where one of the saw blade manufacturers recommended soaking blades in kerosene to remove pitch. I was wondering how this would work for cutterheads? I run a lot of pine for a customer and there is a tremendous amount of pitch build up that has to be removed before I can swap out knives. I am currently soaking them in a container filled with CutterGuard that I'm getting from Weinig, but even after soaking for over three hours there is still a lot of pitch that still hasn't softened. I'm looking for some ideas that may be cheaper or faster. What is everyone else using?

From contributor R:
Are your cutters HSS or Carbide? Carbide can be degraded by caustic cleaners so you need to be careful. Have you contacted your supplier to find out what they recommend? Last thought, if you spray the cutters with cooking spray (yes, like Pam) the pitch will tend to stick a lot less making cleaning much easier.
