Bernite 31 is an alkaline cleaner used to remove heavy deposits of oil, grease and soils from
aluminum and brass surfaces. It is used as a hot soak cleaner with parts immersed in a
solution for a few minutes. It contains NO caustic soda so that this material can be used on
parts that are affected by caustic soda. It will not etch aluminum, nor will it darken brass
surfaces. It is supplied as a dry powder offering a high degree of alkalinity, wetting and
emulsifying properties.
