Wiper blades

I use Protect all or 303 on the blades. Mine are outside all the time so they take a “set”. I just switch them from side to side a couple of times a year.

I use dawn dish soap to clean the windshield followed by application of a silicon car polish. Cleans the crud better than anything else I have used. As to rainex its ok but the silicone I find is much better as it seems to fill the glass imperfections making it very smooth and lasts longer than the rainex.

The use of microfibre towels is also needed instead of just any rag, Tshirt etc. The microfibre towels also work well with the polish to apply then wipe down. Dirt-dust will be removed just by turning on the wipers without the spray and a damp rag is all it takes to clean the windshield again.

FYI I used the above on school bus windows for over 10 years, they stayed cleaner longer even in Az heat and dry.

Thank you, good advice. I don’t get the wax at the car wash and am diligent about wiping the wiper blades with window cleaner from time to time. I’m going to try the Rainex. Thanks!

Agree...after cleaning, apply Rain-X, excellent product!

Good cleaning....soap/water thoroughly rinsing and then squeegee dry or micofiber towel

Afterwards ...Apply Rain-X
*Follow cleaning/applying instructions on bottle!

Light rain...won't need wipers and when you do use them they will not shudder


Had that shudder issue when bought truck brand new in 2007
After using Rain-X...no more shudder---reapply yearly
**And trucks sits outside in AZ

In owning and/or driving probably 100 different vehicles in the 30+ years I've had a drivers license, I cannot say I've ever heard of this phenomena.
What is it that makes a windshield a problem for wiper blades?

The wipers should function properly for several years, unless an obvious reason, such as sitting in extreme sunlight/heat continuously.

Another issue that will cause the wiper shudder you describe, is using hot wax treatment at the car wash. Try giving your windshield a good cleaning when replacing wipers, to avoid contaminates.
