The product disappointed me, it was applied on a clean windshield according to the instructions and the glass became even more cloudy than before! I had to use a different product to clean it.

In the car it worked perfectly only the same night, the next day it wanted again and did not work at all with sunglasses and a mask

Waste of money, I followed the instructions exactly, let it dry as it says, but the windows still get foggy. I sprayed and wiped it immediately, hoping it would do something, but still no luck. I emptied over half a bottle in one day and nothing. Stay away!
