how to clear foggy windshield

If the inside’s fogged, hit the demist setting, turn A/C on, set warm air, fan high, recirculation off, and crack a window—then finish with a clean microfibre if needed. For exterior fog, use the wipers and gently warm the glass; cold, dry air plus A/C helps here too. Don’t smear it with your sleeve unless you enjoy streaks that look like modern art. Keep the glass surgically clean—grime attracts moisture like seagulls to chips. Prevention is simple: dry wet mats, replace a clogged cabin filter, and consider an anti‑fog treatment. Clear screen, clear head; now go see where that fog came from in the first place.
