Selecting the right option

If you need a non-flammable cleaner, the NF Contact Cleaner 400g has no flash point, but CRC warns it may be harmful to some plastics, for example ABS, PEBAX2533 and polystyrene. The CO and QD versions are described by CRC as plastic safe but are extremely flammable aerosols.

For cleaning electric motors and larger equipment see CRC Aerosol Lectra Clean Electric Motor & Equipment Cleaner 400g.

Using it

Do not use on energised equipment. Shut off the power and isolate the equipment before spraying, and let the surface dry completely and the area ventilate before power is restored.

CRC's directions differ slightly by version, so read the directions for the pack you have. Details are listed against each pack.
