How Long Do Wiper Blades Last?
Reviewed by GarageDex editorial
GarageDex's data shows wiper blades last about 6 to 12 months. What kills them isn't use so much as sun and heat - UV and ozone harden and crack the rubber whether you wipe or not. Hot, sunny climates are nearer 6 months; mild, shaded parking gets closer to a year.
Why they wear out
- Sun & heat - UV and ozone harden and crack the rubber; the main factor.
- Grit - dust and debris abrade the wiping edge.
- Ice & snow - scraping and freezing tear the rubber.
When to replace them
The moment they streak, chatter, or skip in your line of sight, swap them - it's a 5-minute, no-tools job. Most cars use two different front sizes, so look up your exact wiper sizes first, then see how to replace them.
Frequently asked
How often should I replace wiper blades?
About every 6-12 months, or sooner if they streak, chatter, or skip. Sun and heat degrade the rubber faster than actual wiping does, so even lightly used blades wear out on a schedule.
What are the signs of worn wiper blades?
Streaking or smearing, a chattering/juddering noise, skipping across the glass, or visible cracks and splits in the rubber edge. If they leave lines in your line of sight, replace them.
Do the front wipers use the same size?
Often not - many cars use two different lengths for the driver and passenger side, and there may be a separate rear blade. Look up your exact sizes before buying.
How can I make wiper blades last longer?
Park in shade, clean the rubber edge with a damp cloth occasionally, lift the arms off the glass in winter to prevent freezing/tearing, and never run them dry on a dusty windshield.
