How do I remove dried glue from my clamps?
How can I remove dried-on glue from my bar clamps?
—Michael Washburn, Irvine, Calif.
When you can't just pop glue off with a putty knife, Michael, throw in a little heat or moisture. We get the best results using a heat gun, as shown below, to soften the glue; it peels off easily once warm enough. If you don't have a heat gun—they sell for about $40 to $70—try a common hair dryer. It might take longer, though, depending on its heat output.
You can also soften most wood glues by wrapping a hot, wet towel around the affected area. You'll likely need to repeat the application a few times until the glue softens sufficiently, then scrape it off. Afterward, dry the clamp thoroughly to avoid rust and corrosion.
