My 2020 Audi S5 has an issue with the interior windshield fogging up. I can use the windshield blower to clear it, but the fog returns pretty quickly. I’ve adjusted interior temp. No real help. I’ve cleaned the windshield interior. Better for a drive or two but the fog/haze/film returns. Is there a product anyone can recommend for cleaning windshield and perhaps deterring the fogging? Thanks!
