Good question about bandsaw blades Kelly. I've cleaned mine with the Trend product but it's time consuming, not easy, and it does get gum on the wheels but doesn't seem to be a problem after. It was me that mentioned the WD40. It did a great job of getting the residue off that the Trend left on one of my blades which is why I want to try just the WD40 next time I need to clean one. You never know until you try as the saying goes.
I always un-tension my BS blade when I'm done with it so I would have cleaned it like that but I don't think it matters.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
