When you are in the shop, there inevitably comes a time when you have to clean up after yourself. Trend’s new Tool & Bit Cleaner is supposed to make that task easier when it comes to your tools. You spray it on, then wipe it off, to remove resin, pitch and other gunk from your saw blades, drill bits, files, etc. It’s formulated to lift the dirt away from the tool, rather than eating through it, with a composition that is biodegradable, nontoxic and nonflammable — plus offers rust and corrosion protection. An 18-oz. bottle of Tool & Bit Cleaner cost $11.65 in 2010.
