Windshield Care Tips to Avoid Cracks & Streaks

Updated July 26, 2026

Keep wipers fresh

Streaking, chattering, or smearing usually means worn wiper blades — replace them every 6–12 months. Old, hardened rubber not only smears but can scratch glass and drag grit across a chip. Fresh blades are the cheapest windshield upgrade there is.

Protect the glass

  • Keep a safe following distance behind trucks that throw road debris (Delaware's I-95 corridor is notorious)
  • Don't blast a hot defroster onto freezing, chipped glass — warm it gradually
  • Never use hot water to de-ice; use a scraper and de-icer
  • Fix small chips fast before winter spreads them

Clean it right

Use an automotive glass cleaner (not ammonia-heavy household cleaners if you have tint) and a microfiber cloth for a streak-free finish. Keep your washer fluid topped up with a winter formula. And if a chip does appear, a quick repair — often free with insurance and no Delaware sales tax — keeps it from becoming a replacement.

Frequently Asked Questions

How often should I replace wiper blades?

Every 6–12 months, or as soon as they streak, chatter, or smear. Worn blades reduce visibility and can drag grit across the glass.

What's the safest way to de-ice a windshield?

Use a scraper and de-icer and let the defroster warm the glass gradually. Never pour hot water on frozen glass — the sudden temperature change can crack it.
