I recently read a letter to the editor of the Star magazine concerning the shuddering of windshield wipers. The gentleman wrote that he tried cleaning his windshield with coca-cola with little relief. Finally he found Mercedes Intensive Window Cleaner at his local dealer (cost about $20 for 8.5 ounces). After cleaning the windshield with this cleaner the shuddering of his wipers ended.

I shudder at paying premium price for cleaning rubber and glass. I use vinegar, Dawn
detergent and water...with a light touch and a 3m pad for the glass. Periodically, I also
pull out the steam vapor machine to clean the glass. I use silicone dressing from a $5
can on wiper blade which has lasted 10 years now. Anecdotal, of course, but I'm still
on the same Bosch wiper I've had since about 2010. I park the car indoors so it isn't
subject to a lot of environmental cooties 24 hrs. I'm not working now so I need to
mix my own stuff when I can.

BWhitmore, try some Meguiar's Cleaner Wax on the windshield. I do the windshield every time I wax our MB vehicles.

I do the opposite and remove the wax from the glass. Wipers need some friction to ensure it flips to the other wiping edge. If not it will shudder. I use 0000 steel wool and windex every few months. Wipes clean and doesnt streak.

I don’t have a problem with shuddering wipers myself. Just wanted to share an interesting piece of info found in the Star magazine.

thank you for looking out for us. I've read many good tips and info from the STAR publications over the years

I polish the windshield with cerium oxide. It cures all ills. Then I follow with a glass wax like Rain-X.

Well for my 2 cents, I think its safe to say the Coca-Cola of nowadays won't clean much of anything and may just make a gooey mess. The old formulation of Coke contained citric acid. That was the ingredient that did the cleaning. It was great for cleaning battery cable terminals, ect.

As far as getting a good deep clean on your windshield, for me I use Purple Power RV/ boat wash concentrate mixed down with hot water. Purple Power is a great detergent for removing road film. A gallon costs $8 at Walmarts and it goes a long way. If you just want to clean the windshield you might want to keep it off the paintwork since it is not PH balanced and will strip any wax you've put on. I use it all the time to wash my vehicles when I want to re-wax. It's great and doesn't hurt the paint.

Once, the windshield is washed, I use a clay bar and bar lube to go over it. That does a great job removing any contaminates, bug tar, ect left behind. You can finish up using Rain-X or something similar. I've had good success using LiquidGlass. It's similar to Nu-Finish and really repels water. 303 protectant can be used to extend the life of your wiper blade/s.
