Clean again

My shiny, luxury BMW was lately not really impressive. It rather looked like a construction vehicle and actually that was what it was used for.
But today I used the high pressure cleaner to clean a part of our house wall, so it can be painted. I used the opportunity offered and cleansed my car too. Only water, but it helped. The lacquer can be used as a mirror again, as can be seen in my blip.
I am not good in cleaning cars, for me it is more like an item of use than an ornament. But in order for a long life it is still necessary to keep it clean, prevent dirt and algae or even moss to settle in.
