Hand wash & machine wash using normal or polycarbonate friendly detergents. For heavy soiled glasses, soak in lukewarm water before cleaning. When hand washing, only use a soft sponge and avoid repetitive movements like twisting whilst cleaning.
At all cost, avoid scourers or cleaning clothes that are abrasive. These will make your polycarbonate glasses appear scratched and cloudy. Do not use these on polycarbonate glassware!!
Glass scrubbers are also damaging to polycarbonate surfaces. However it is recommended that if you need to use these cleaning devices, that you fold a kitchen clothe over and place it over the brushes to create a protective barrier.
