WD40 Hack on Wiper Blades! Does it really work?

I was recently out driving in some wet weather and my wiper blades started to smear and screech.

After investigating replacing the wiper blades with OEM blades, I figured that I would give the popular car hack with other DIY'ers a go which uses WD-40 spray to revitalise and revise wiper blades. Purchase your WD-40 here:

If you're not in the situation to replace your old ones and the rubber blades still seem in good condition, then after doing this I do think that this WD-40 hack is certainly worth the try.

This video will show you what you'll need, how to do the hack, and does it really work.

In this video I am demonstrating this using my 2011 Mercedes ML300 (W164).

I really liked this video for these reasons: Concise, useful, no music.

I started using this trick a while ago and so far my blades do a clean wipe and are also quiet. I am sold!

BLINK dude BLINK you're freaking me out BLINK YOUR EYES

Denatured 95% alcohol is good, too. Evaporates completely, no residue - good for copy machine/printer rollers, too. I learned it from an instruction sheet on some wipers that said to use it before 1st use. Gets that same black stuff like the wd-40. Standard cleaner for tape recorders back in the day....

I clean my wiper blades in the same manner but use household non streak window cleaner spray . I still get a black deposit on the paper at first but it soon becomes clean . No smearing, no squeaking, no bouncing. Simple!

Hi Drew, on some wiper arms, wd-40 can be sprayed to loosen the hinge or elbow, that's supposed to flex downwards, with the spring underneath. Wd-40 will loosen a corroded hinge, allowing the correct pressure of the arm and blade on the windshield.

A better test would be doing one wiper blade with WD40 and wiping the other blade just with a bare cloth, or water. Compare the two.

I saw this tip on Silver Cymbal's page. I clean the inserts of the blades for a Honda and for a Toyota about twice a year with WC-40. In addition to being free of streaking, the blades are quiet, too. Quiet, like you-can't-hear-them quiet. This has allowed me to use the same blades for more than two years. I have a 2010 Pontiac G8GT (Holden Commodore) with the one-piece blades and still use the original blades.

I've been doing this to my Bosch blades for two years now about every 4 to 6 months and I've not had to buy any new ones yet. It also helps to polish your windshield with a plastic polish or even car wax.

We don't use wiper blades here in UK we use a periscope, it rains all the bloody time😂

A buddy of mine owned a gas station and he had this rubber cleaner for repairing tires that he'd use on wiper blades. He called it, "recutting the blades". It worked pretty good. So if you can get ahold of whatever that stuff is then give it a go.

Worked a treat on my Mercedes wiper blades ( Smart fortwo 2019 ). I agree with others that it removes dry rubber gunk and also softens and revitilises the rubber underneath ie renews the blade. Great hack

In my experience WD40 and rubber don’t go well together, despite what it says on the can. Been successfully cleaning my wiper blades with vinegar for years with great success, 👍

[warrenb]

Good tips, Drew. Glad it's workin'. Another thing I do is clay-bar the windshield. It's amazing how much getting all the gunk off helps wipers work. I also use Rain-X so I don't have to use the wipers, but that's a different video.

I'm sure brush makers don't really appreciate the WD40. Another good application I discovered for the WD40 is removing the old glue from stickers and tape, both on glass and sheet metal.

[flashUSA]

Works like a charm. I've been doing this for many years.

[melaniezette]

I use silicon oil, for some time it lefts traces on the windshield but it protects rubber. Very useful for rubber parts.

The WD40 may clean the road grime off your blades but it will also cause the rubber to degrade much more quickly. This is why the people who sell those $70 wiper blades just love it when people use WD40 to "fix" their wiper blades. It means more business for them, not less. Soap and water will also clean the grime off your wiper blades, but without damaging them in the process.

Great job you saved me the replacement of my blades for a little longer.

Been using this hack for a while now, hasn't let me down yet! I've had the same set of blades on my older vehicle for over 5 years now and they work as good if not better than the day I first installed them when they were brand new!
