A pro tip for stopping your windows fogging up, don’t use aircon. Most of the fog is trace refrigerant in the system being blown onto the glass.
Turn your aircon off and clean your windows thoroughly and they will fog up much less and not need cleaning as often.
During those couple of days in the summer when aircon is actually needed, set it to feet and forward vents and not the screen. After use keep it off the screen for a good while to allow any gas to clear the system.
Had my current car 3 years and 1 month, used aircon 2 or 3 times and cleaned my windows maybe every 3 months.
If I seem a little strange, that's because I am.
