Windshield wipers obnoxiously scraping

Jimmy Brooks · Apr 9, 2020

I’ve had this issue for as long as I can remember and I’m finally fed up with it. My wipers make a scraping noise every time they wipe to the point were it sounds like their frozen and there is no water on the windshield. It’s not the wipers I’ve had numerous sets and they’ve all done the same, it’s almost like the windshield is extra sticky to the wiper blade. Anyone had this issue or know how to fix it, Thanks.

Try wiping the road grime off the blades using a paper towel and rubbing alcohol or an alcohol wipe. That usually works for me.

I've tried experimenting with different brands as well. I'm currently using Bosch blades on the front and a Valeo on the rear glass with good results. I had a ton of chattering with the OEM blades, to the point that my wife would mock me whenever we rode together in rain.

I’m using Bosch blades on the front as we speak I’ve tried cleaning them with a paper towel and still the same result. I haven’t tried using rubbing alcohol not sure if that will work. I’ve tried waxing the Windshield also not sure if that would make a difference, heard it worked for some. The wax I used was old so I picked up a new bottle and I’m going to try again tonight. Any other good suggestions.

Before trying to wax the windshield, maybe Rain-X is a better option. At least it is made for glass. But from my experience, you want just clean glass. I was recently behind a diesel truck that was spitting some sort of diesel dust onto my windshield. Soft Scrub cleaned it up nicely.

Wiping the blades with a paper towel alone won't help. You need the alcohol to cut through the road grime that is on the blades.

I agree with @PaulLR3 . I use either Rain-X periodically, or a product called WashWaxAll that is a waterless wash fluid for my exterior. It is basically a detailing product for very lightly soiled vehicles; the same type of spray you would use when using a claybar. It also works great on glass.

Used rain-x before coming here and it didn’t work. But luckily got it solved. Took 30 mins cleaning the blades with rubbing alcohol then waxed the windshield and boom silent. Thanks for all the tips and help!!

It's amazing how much "crap" get on the windshield especially after a rain. Much less ground and air traffic because of the pandemic could help. Anyway, like others I've had good luck with Rain-X, but the other thing I do is wash the wiper blades with a soapy rag, then wipe them off. Then I spray silicone onto a paper towel and wipe the wiper blades with that and let it dry while lifted from the windshield. That seems to work very well and extends the life of the wipers.

303 Aerospace Protectant is supposed to help prolong wiper lifespan, and reduce wiping problems. They used to sell a box of packets with small wipes that would treat several wipers, but appears these are NLA. Instead, just use your normal bottle of 303, squirt on a cloth, and wipe down the rubber wiper inserts periodically.

303 Protectant is great stuff for most interior and some exterior surfaces:

I will try this product. For as methodical as I am when washing my Rover, I give short shrift to the wiper blades during the soapy phase. I notice this every time I'm finishing it off with the synthetic chamois. When I wipe the blades they always leave a black streak on the cloth...
