Over time, resin builds up on blades and bits, which can cause friction and burning in cuts. This is why occasional cleaning is essential. And all you need to do it correctly is the right cleaning product, a couple tools to remove resin, and a corrosion inhibitor.
The proper cleaning product to use on bits and blades is a matter of some debate. Everything from basic household cleaners to baking soda to oven cleaners is sometimes suggested for cleaning. From personal experience, I've found it’s probably worth investing the $10 to $20 in a cleaner designed specifically for the job. You can see some options in the photo. These cleaners are formulated specially to clean bits and blades and work quickly.
To clean your tools, you’ll want to find a container that the bits or blades fit in, and let them soak in the cleaner for 15 to 20 minutes. Then use a synthetic abrasive pad (like Scotch-Brite) or a brass bristle brush to remove resin from hard-to-reach areas like the shoulders and gullets around teeth and cutting edges.
Most of the cleaners recommended for use on bits and blades are water-based. So after you clean and dry them, spray on a corrosion inhibitor like WD-40 or a dry lubricant like the ones shown here to keep them looking and working their best.
