What will get rid of moss growing on my window seals?

My 2013 Volkswagen Up in white is gradually becoming an Up in white with green edges. The furry side window seal/wiper is growing green moss or algae. It doesn't get washed often enough I know, but how do I kill it once it has grown.
I'm thinking patio cleaner bleach and a pressure wash but then I might need a respray. Are there techniques and products out there better suited?

Regular cleaning is the best thing you can do. But to get rid of what's there, use a diluted anti-bacterial cleaner (test it on a small, hidden area to make sure it doesn't do anything weird) and then give it a good scrub with soft-bristled toothbrush. After that, use a pressure washer to clean the car as normal and try be more regular with your cleaning to keep it at bay.
