Kagabi, after the torrid rains in the afternoon...drove from Manila to Cainta...sobrang fogging ng rear windhshield ko! Wala na akong makita sa likod, even the headlights of the cars behind are barely visible!!

What could have caused this? Sobrang lamig ng aircon ko? High humidity outside after the rains?

Lahat na ng aircon settings sinubukan ko but nothing worked! Tried turning A/C off, then opened it again, closed the circulation, then opened it, opened some windows, closed them again. Had to go down twice and wipe off the rear windshield pero sandali lang ayun na naman yung fogging!!

Any inputs or information of similar occurence will help. Also, may produkto ba na pwedeng ipahid sa rear windshield para maiwasan ang fogging?
