MPH System Specialties has come out with a lubricant, cleaner, and protecting agent all in one, called Strike-Hold. Originally developed for the U.S. Army, Strike-Hold can be used on any object susceptible to rust or corrosion, including cell phones and hand-held radios. It doesn’t wear down rubber, plastics, wood, or paint. Strike-Hold removes corrosion and rust and leaves a protective coat to prevent further corrosion and to protect against the effects of dirt and moisture.
