Rustlick 631 is a moisture-displacing rust preventative and penetrating lubricant designed for long-term protection of ferrous parts stored indoors. Available from ITW Rocol, the material spreads into scratches and pores to displace moisture. The transparent, dark-brown fluid leaves a light, oily, transparent film.
Rust protection can last as long as two years indoors, the company says. A heavy-duty detergent cleaner or other degreaser can be used to clean metal surfaces after storage. Such cleaners are more effective when used at increased temperatures or with increased pressure or agitation, the company says. Useful for virtually all metals, the lubricant is available in a 12-oz. aerosol can or in 1-, 5-, or 55-gallon containers.
