BMW Original Concentrated Windshield Washer Fluid for Winter And Summer Oil Removal Anti Freeze Car Care Auto Maintenance

This glass cleaner is exactly like the one I buy from the official BMW store and app, and it's definitely genuine. It's a bit cheaper than the 4S store, so why not save some money? I've been using this cleaner for a while now, and it works really well at removing dirt compared to other regular ones. Plus, it smells nice and prevents freezing. I got the one-liter bottle that doesn't need to be mixed with water, but if the temperature's above freezing, I think it's fine to dilute it. It cleans perfectly without leaving streaks. I'm very satisfied.

It's decent, seems like the real deal.
