CRC 5-56 Multi-Purpose Lubricant 400g Aerosol

CRC 5-56 Multi-Purpose is a service spray that CRC says penetrates, lubricates and protects against corrosion. It has a continuous, self-repairing film, contains no silicone and is described by CRC as safe for all metals and alloys, and for most painted surfaces, coatings, plastics and rubbers.

It is supplied as aerosols (175g, 270g Permastraw and 400g), trigger packs (500ml and 1L), a 4L bottle and 20L and 200L drums. CRC publishes separate safety data sheets for the aerosols and the liquid packs, and their hazards differ, so check the pack you are buying in the hazard section and the variant details.

Selecting the right option

For marine use CRC makes CRC 5-56 Marine Multi-Purpose Oil 300g. For a pen applicator see CRC 5-56 Multi-Purpose Pen 12ml, and for the NF aerosol formulation see CRC 5-56 Multi-Purpose Non-Flammable Lubricant 400g - Pack of 6; each has its own data sheet and hazard classification.

Using it

Do not spray or apply while equipment is energised.

Aerosols: hold the can about 30 cm from the surface and spray liberally. Liquid packs: apply or spray liberally.

For greater penetration let it soak in, then wipe off excess.

For flooded engines CRC says to spray all electrics and leads liberally. When cleaning, test a small area first for colour fastness.

Aerosol packs: protect from sunlight and do not expose to temperatures above 50 °C. Keep away from heat and ignition sources. Do not pierce or burn the can, even after use. The pressurised container may burst if heated. Liquid packs: store in a well-ventilated place and store locked up; keep away from heat, hot surfaces, sparks, open flames and other ignition sources.
