Introduction to Restoring Windshield Wipers

Having clean and properly functioning windshield wipers is an essential component of safe driving. However, over time wiper blades naturally degrade from exposure to sun, rain, snow, and debris. The result is streaky, noisy blades that obstruct vision and increase risk on the road.

Fortunately, there is an easy 30-second hack that can restore wipers to like-new condition. It requires only two inexpensive household items and takes just half a minute to complete. Consistently applying this trick can extend the lifespan of wiper blades for years, saving drivers money while ensuring optimal visibility and safety.

The Problem: Streaky, Noisy Windshield Wipers

As wiper blades are used over months and years, they accumulate dirt, tar, oil, and other gunk on their rubber edges. This buildup causes them to skip and squeak across the windshield, leaving behind streaks that make it difficult to see. In addition to reduced visibility, noisy and jumpy wipers are simply annoying for drivers. They represent yet another distraction while trying to concentrate on the road.

The Simple 30-Second Solution

With only two supplies - an old sock and a can of WD-40 - drivers can restore their windshield wipers to like-new condition in just 30 seconds. This trick deep cleans the wiper blades, removing built-up grime so they glide smoothly once again. As a bonus, taking an extra minute or two to also clean the windshield glass helps prevent new debris from re-sticking. Consistently applying this wiper blade restoration every few months can rejuvenate them for years of optimal use.

When to Replace Your Windshield Wipers

While the windshield wiper restoration trick is extremely effective, it does have its limits. At a certain point, wiper blades become too worn out and damaged to function properly. Here are two clear signs it’s time to replace them completely.

Visible Damage

Carefully inspect wiper blades for any cracks, chips, or tears. These defects allow air, water and debris to pass through the rubber edges, preventing smooth and consistent contact with the windshield. Damaged wiper blades will continue to streak no matter how much restoration is attempted. When such visible deterioration is present, the only remedy is getting new wiper blades.

Poor Performance

If wiper blades are intact but just fail to adequately clear water and debris from your line of sight, their usefulness has come to an end. Declining performance even after thorough restoration indicates the rubber has hardened past its prime. Another clue is wiper blades that leave wispy trails of smeared water behind. At that point, it's best for safety to invest in a fresh set.

How to Restore Windshield Wipers

With these simple steps and materials, dirty, squeaky windshield wipers can be restored to optimal condition in less than 30 seconds:

Materials Needed

  • Old sock or rag. The rougher texture, like terry cloth, is ideal for scrubbing.
  • Can of WD-40 lubricant. This penetrates and dissolves built-up gunk.

Degrease the Blades

Spray WD-40 liberally over the sock or rag. Flip the wipers out to access the blades. Then scrub back and forth as if brushing teeth, removing layers of contaminated film. Let the WD-40 sit for a minute before operating.

Clean the Windshield

Finally, use glass cleaner and a paper towel or newspaper to thoroughly wipe down the windshield. This prevents freshly cleaned wiper blades from immediately recollecting dirt and oil.

Benefits of the Windshield Wiper Hack

Saves Money

Frequent wiper blade restoration allows them to last for years longer than they otherwise would. The small upfront investment in WD-40 and rags is paid back over time by not having to continually buy replacement windshield wiper blades.

Extends Wiper Life

Removing accumulated gunk rejuvenates the rubber edges of wiper blades. Rather than drying out and cracking prematurely in the sun and elements, keeping them clean enables years of smooth function.

Restores Optimal Performance

Streaking and chatter are eliminated by re-smoothing the wiper's edge and clearing its path on the windshield. Vision and safety are dramatically improved by restoring silent, consistent wiping.

Frequently Asked Questions

Here are answers to some common questions about restoring windshield wipers using the simple DIY hack:

Does this trick work for rear wiper blades too?

Yes, the WD-40 cleaning method works equally well for back window wipers. Just flip them outward to access the blades, then scrub with the soaked rag to remove stuck-on grime. They’ll wipe like new again.

How often should I do this restoration?

A good rule of thumb is to thoroughly restore wiper blades every 2-3 months. That prevents too much buildup while getting years more use from each set. More frequent cleaning, such as at oil changes, yields even longer blade life.

What about winter and freezing weather?

There’s no need to worry about using WD-40 in frigid conditions. It contains anti-icing agents allowing it to penetrate grime layers even below freezing. The restoration trick remains equally as effective for ice, snow and winter salt.


With this simple 30-second DIY hack, drivers can save money and dramatically extend the usable lifespan of their windshield wipers. Restoring them every few months maintains perfect visibility for safety in all weather conditions. Give this trick a try - once you do, you’ll make it a regular routine!


Q: How long does this hack take?
A: Less than 30 seconds. Simply degrease the blades with WD-40 and a rag, then clean the windshield with glass cleaner.

Q: What if my wipers are damaged?
A: Unfortunately if there are visible cracks, chips or other defects, this hack won't restore them. You'll need to replace damaged blades.

Q: Can I use a napkin instead of a rag?
A: In a pinch you can use a napkin or tissue, but they won't hold up as well over time. A textured rag works better for scrubbing.

Q: How often should I do this?
A: Repeat whenever streaking or noise returns. For optimal results, make it part of your regular car maintenance routine.

Q: What causes windshield wipers to streak?
A: Buildup of grease, tar and other debris. By degreasing, you remove this residue so blades glide smoothly.

Q: Why clean the windshield too?
A: Getting rid of grime on the glass prevents it from quickly building back up on the blades.

Q: Can this be done at a gas station?
A: Yes, just lift the blades and degrease with WD-40. It's quick enough for pit stops, but do a more thorough cleaning later.

Q: Does this really make wipers last longer?
A: By removing oil and grease buildup, you extend the life of the rubber. Well cared for blades can work great for years.

Q: What's the main benefit of this trick?
A: Restoring a clear view is the top advantage. No more annoyance from streaks or struggling to see in bad weather.

Q: Does WD-40 damage car paint?
A: No, WD-40 is safe for use on car exteriors. Just avoid overspraying paintwork when cleaning blades.
