Tired of streaky windshields impairing your view? The challenges of interior glass cleaning come from multiple unseen factors.
Clean interior windshields with microfiber glass towels and ammonia-free cleaner - working in sections with multiple passes for perfect clarity.
Auto detailers emphasize treating interior glass differently than exterior due to facing different contaminants and environmental conditions.
What is the best thing to clean the inside of your windshield with?
Your household cleaners likely cause more problems than they solve when it comes to windshield clarity.
Use these professional-recommended products:
- Ammonia-free glass cleaner (prevents film)
- 70/30 blend microfiber towels (250-300 GSM)
- Plastic razor blades (for stubborn stains)
- IPA solution (for prep cleaning)
- Rubber-tipped tools (for tight edges)
Product Comparison:
| Product | Pros | Cons |
|---|---|---|
| Commercial glass cleaner | Streak-free | Chemical smell |
| Diluted IPA | Deep cleaning | Requires buffing |
| Vinegar solution | Natural | Temporary results |
| Steam cleaner | Sanitizes | Condensation risk |
| Clay bar | Removes films | Time-consuming |
Essential: Never use paper towels - they scratch and lint.
How do I make my windshield crystal clear?
That perfect showroom shine requires addressing the three main enemies of windshield clarity in sequence.
Three-step process:
- Pre-clean with rubbing alcohol (removes films)
- Deep clean with glass cleaner (lifts grime)
- Final polish with waffle weave towel (prevents streaking)
Common Mistakes:
✖ Using household glass cleaner
✖ Cleaning in circular motions
✖ Single-pass wiping
✖ Ignoring edges/corners
✖ Applying product directly
Pro Tip: Clean when glass is cool and out of sunlight.
How to clear a foggy windshield from the inside?

- Replacing cabin air filter
Fog Sources & Solutions:
| Cause | Solution | Prevention |
|---|---|---|
| Plastic off-gassing | IPA wipe-down | Regular cleaning |
| Smoking residue | Enzyme cleaner | Smoke outside |
| Old wax/sealants | Clay bar | Separate towels |
| Tint adhesive | Ammonia remover | Professional install |
| A/C bacteria | Vent treatment | Filter changes |
Warning: Some anti-fog coatings create glare at night.
