ᐅ Glass protection for windows and showers

Hello everyone,

what do you think about treating windows with a maintenance product that creates a water-repellent effect? Does this make sense for windows, especially south-facing ones that get a lot of sunlight?
In my idea, I would treat the windows so that when it rains, the dirt is washed away more easily. Is that actually how it works?

I’m thinking about doing the same for the shower. I’d like to treat the inside of the glass so that water droplets run off more easily and don’t stick until they evaporate, leaving lime scale stains.

There are countless maintenance products for cars, but I’m not sure how effective they really are since I haven’t used them.
I’m also unsure how these treatments hold up with warm or hot water from the shower.

Has anyone tried this before?

Nothing at all, as long as they are nanoparticle-based. That stuff is harmful and, in my opinion, should be banned.

Best regards

We also tried it at home on our glass shower wall – you still have to scrape off the water afterward. However, it must be said that it was much easier to remove the water droplets than without the product applied.
