It isn’t just your circular saw blades that collect dust and debris, your joiner blades, planer blades, jigsaw blades and any other blade that cuts, plunges, gouges, scrapes or carves will collect gunk (gunk, of course, is the technical term for the residue that accures on your cutters after a hard day’s work). Accordingly, keep all your cutting blades clean. Frequently wipe them down and periodically give them a good, thorough cleaning. It’s good practice to also keep some WD-40 on-hand for tougher gunk build-up.
