CRC 5.56 is a multi-purpose service spray that penetrates, lubricates and prevents corrosion. The original toolkit in a can.

CRC 5.56 forms a thin film that lubricates moving parts for smooth action and silences annoying squeaks and squeals.

Superior penetrating power breaks through rust and corrosion, loosens rusted parts, displaces water from wet equipment and cleans away scale and dirt. It protects metals from corrosion caused by humidity, salt air and other corrosive atmospheres.
