Screw Cleaning Tool Beats a Wire Brush

A hand-held belt polisher with four sizes of rotating jig reportedly provides a gentler way to clean charred plastic off screws after torching or purging them.

A hand-held belt polisher with four sizes of rotating jig reportedly provides a gentler way to clean charred plastic off screws after torching or purging them. Processors typically use wire brushes, which can damage screws. General Plastex in Barberton, Ohio, introduced the rotating bench jig and polisher last year. An operator holds the polishing unit against the rotating screw. The motorized bench comes in four sizes priced from $3500 to $8000.
