windex for car windows

Short answer: Windex is fine on plain automotive glass, but keep it away from aftermarket tint films—ammonia can wreck them faster than a summer storm.

For interior glass and screens, use an ammonia-free cleaner and a decent microfibre; spray the cloth, not the surface, and avoid soaking seals.

If you’ve got factory privacy glass (tint in the glass), you’re generally sweet—it’s the stick-on film that sulks.

Work in the shade to dodge streaks, and if there’s that greasy haze, a little isopropyl alcohol mix sorts it out nicely.

Bottom line: fine on bare glass, no on tint film, and never on infotainment or dashboards unless you fancy smears worthy of modern art.
