Abstract
Rinse aid compositions based on alkyl polyglycoside surfactants attack plastics, in particular polycarbonate, to a much lesser degree than rinse aid compositions based on other types of nonionic surfactants. It is preferred that the compositions also comprise an anti-foam agent, preferably a ketone having more than 25 carbon atoms.
