Easy answer - go to an auto parts store and purchase "Anti Fog"; once applied to the inside of a window, the moisture will not adhere ( same company makes "Rain X" for outer windows )

Clean the inside glass with isopropanol alcohol, then with pure white vinegar. Then buff on a light coat of rainX.

Is recharging the AC an option? Or is frugality the word of the day? Are you interested in keeping it or no?

These are great suggestions, but what's the big picture?

Good luck

That would be impossible.

Hi guys. I drive an old 1992 LeBaron convertible, and in the humid mornings my windshield is fogged up so bad that I can't see when I drive. How can I clear it up?? It's dangerous and the visibility is awful when I try driving. If this helps my AC isn't recharged so no cold air for defrosting. Should I use hot air to defrost it with the top and Windows up? What should I do? Best concrete answer gets 5 stars.
