Cloudy, streaked auto glass reduces visibility and ruins your car's appearance, yet improper cleaning causes permanent damage many owners don't notice until too late.
Use specialized glass cleaner and microfiber towels in straight-line motions. Never paper towels or circular wiping.
90% of auto glass scratches come from improper cleaning tools and techniques rather than actual road debris.

Those annoying streaks aren't just cosmetic - they can create dangerous glare situations when driving toward sunlight or streetlights.
Clean glass in cool shade using vertical exterior strokes and horizontal interior strokes. This helps identify which side streaks appear on.
Glass Cleaning Don'ts:
- Newspaper (leaves residue)
- Household cleaners (cause haze)

- Dirty towels (grind debris)

Pro Tip: Clean glass first before washing other surfaces to avoid contaminating towels.

The wrong products create permanent haze or attract dust faster - auto glass needs specialized solutions regular cleaners can't provide.
Use ammonia-free automotive glass cleaner with microfiber glass towels (at least 300 GSM).
