@letsbetechs: A quick hack I saw floating around involved using a bench grinder with a wire brush to clean up a smaller, mangled hand brush. I was curious if my trusty wire wheel would be sufficient in place of a bench grinder, so I put it to the test! What do you guys think—was it a solid improvement? Next time, maybe I can try a comparison between a wire wheel and a bench grinder to see which one actually straightens better. My guess? The bench grinder’s longer, stiffer bristles will take the win. Let me know your predictions in the comments! #hvac #hvactech #hvaclife #tooltip #toolhack
