6 in 1 is formulated with the revolutionary additive Molbaumin which provides high film strength and cleans and lubricates. Use as a penetrating and lubricating fluid. Protects against corrosion and rust, displaces water, reduces friction and will not harm electrical contacts. Ideal for control cables as its blue colour enables you to see when the fluid comes out of the other end. Unlike most de-watering fluids 6 in 1 leaves behind a protective coating for a lasting effect.
