Some poorer polycarbonate qualities will soften at quite low temperatures making them scratch and get cloudy, even crack, when used in industrial dishwashers with a relative high temperature (typically 75 to 85 degrees Celsius).  Using a home use dishwasher or washing by hand using a soft sponge will increase the lifespan of polycarbonate glassware made of poorer and cheaper quality resins. Most materials expand when heated up and will contract when cooling down.  Stacking polycarbonate glassware when they are still warm from […]
