It doesn't really matter if you have a plastic or nylon shower curtain, it needs to be washed on a cool cycle every 2 weeks. There is no getting around this as it will always be damp and therefore a haven for mould to grow. When you wash the curtain also add a few drops of pine and lemon essential oil. The oils will help kill the mould, and will also smell super in the bathroom.
If you have a glass screen in the shower then it is a good idea after each shower to wipe the glass with a window wiper. This will speed up the drying time of the bathroom thus reducing problematic mould growth. For a better clean just use 80/50 vinegar spray and polish clean. If the glass has a build up of limescale add some bicarb soda as a gentle scouring agent.
