A relatively new way to protect your tools from rust involves a special substance placed in an enclosed space, like a tool box or tool chest. This substance gives off protective vapors that spread through the air. Once these vapors contact the metal surface, they form a thin invisible layer that prevents oxidation (interaction of air and moisture with metal). The coating inhibits the formation of rust and corrosion for up to a year. It won’t change the look or feel of the tool. And it doesn’t leave any residue that might interfere with finishing.
You can get these inhibitors in a cup or strip for use in small tool boxes or drawers. The Bullfrog Shield (photo above) is made to be used in larger tool storage containers and tool boxes. They’re also non-toxic and environmentally safe.
