Cleaning metals used in helicopter manufacture. As a result of a search for a generalised method of cleaning metals used in helicopter construction, and which would be safe in all areas, Westland Helicopters Ltd, Yeovil, now uses two Oakite cleaners throughout the factory. Both are alkaline and are supplied in bulk by Oakite Ltd. Both have had to meet stringent AQD approved internal specifications for metal treatment which include requirements that chemical reaction with, or attack by, the cleaner on the metal surface and that tolerances of 0.0001 inch (0.025mm) must be maintained, especially on magnesium.
