Here are a few tips:
Rinse off your slices! The less contact the plastic discs have with solid materials (rub with a cloth), the better. This also applies to cleaning. If wiping with a cloth is not absolutely necessary, it should also be avoided. There is a risk of grains of sand or streaks of dust being polished in. If it is very dirty, it should be cleaned with high pressure (but without contact).
Do not use aggressive cleaning agents! - We recommend plastic cleaners or vinegar water: Basically, both acrylic glass and polycarbonate panes can be damaged by cleaners (glass cleaner, turpentine, paint thinner). Even simple glass cleaners can contain tensides, which can lead to stress cracks in acrylic glass.
