How do you get tree resin off of chain saw blades?

To remove tree resin from chainsaw blades, heat the blade slightly using a heat gun or by running the chainsaw for a few minutes, which softens the resin. Use a plastic scraper or an old credit card to gently scrape off the softened resin. For stubborn residue, you can apply a solvent like mineral spirits or rubbing alcohol, allowing it to soak for a few minutes before wiping it clean. Always ensure the chainsaw is off and cool before cleaning.
