CAN/CGSB-2.42-97

1. Scope 1.1 This standard specifies the physical and chemical requirements for a stain remover used in hard or soft water to remove coffee, tea and other absorbed food stains, primarily from plastic tableware, by immersion. 1.2 The stain remover may also be used on glass and china tableware, although it is not intended for this purpose. It may also be used to remove stains from coffee urns, except those made of aluminum. Due to its tendency to deteriorate and lose oxygen in storage, it is advisable not to purchase more than a six month supply at a time. 1.3 The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use.
