Why Glass Maintenance Matters

Dirty, streaky, or hazy glass isn’t just annoying—it’s dangerous. Clear windows improve visibility in all conditions. Proper glass care also prevents:

• Water spots from hard water and rain.
• Haze from interior films and off-gassing.
• Scratches from wiping with the wrong towels.

Using safe products designed for automotive glass ensures streak-free clarity and added protection against the elements.

Best Cleaner & Protectant: Tough As Shell

Tough As Shell Ceramic Spray isn’t just for paint. When diluted, it works as a streak-free glass cleaner that leaves behind a protective hydrophobic layer.

• Repels rain and water instantly.
• Reduces fogging and smudging.
• Keeps glass cleaner longer.
• Safe for exterior and interior glass.

Pro Tip: Mix ½ ounce of Tough As Shell with 16 ounces of distilled water in a spray bottle for the perfect DIY glass cleaner and protectant.

Best Towels: Softer Than Soft

Even the best cleaner fails if you use the wrong towel. Softer Than Soft Towels are perfect for glass—they’re ultra-soft, lint-free, and won’t scratch delicate surfaces.

• 550 GSM for maximum absorption.
• Streak-free finish every time.
• Safe on tinted windows and interior screens.

Avoid This: Paper towels and cheap rags leave lint and streaks. Always use quality microfiber for glass.

Step-by-Step Glass Workflow

1. Spray diluted Tough As Shell directly onto a Softer Than Soft Towel.
2. Wipe glass in straight lines (not circles) to avoid streaks.
3. Flip towel to a dry side and buff until crystal clear.
4. Repeat inside and outside for maximum clarity.
5. Reapply every 2–4 weeks for hydrophobic protection.

Common Mistakes to Avoid

• Using ammonia cleaners—bad for tint and plastics.
• Wiping in circles—creates swirl marks and streaks.
• Skipping protection—leaves glass vulnerable to water spots.
• Reusing dirty towels—grinds grit into glass and scratches it.
