Windshield - marks from wiper - coatings? (merged thread)

Any chance you are using Rain-X? Rain-X will cause that. Also, I believe that the "hot wax" or whatever it's called at automatic car washes leave a film on the windshield. Over a short time, the wipers will strip that off and deposit it at the edge of the wiper travel.

Has there been salt brine put on the roads recently for cold weather? I get this mostly in the winter when salt or mag-chloride is used to de-ice our roads.

I use Rain-X to get rid of this which works great for me, takes some extra elbow grease and time to do a few passes at it when its real nasty but it always ends up crystal clear for me

polish the glass, lots of different compounds available.

No, I have not used Rain x. Last time I cleaned the windows I used rain x cleaner, but it did not take off that wiper stripe

I've not tried this, but I've read that using a fine clay-bar is good at removing stuff from windshields that regular glass cleaners won't get. Not sure how safe that is, but I guess it would probably depend on the type of clay.

try cleaning your wiper blade with rubbing alcohol. wipe in one direction.

I would give the windshield a good clean (I second the clay bar recommendation) and also clean both wiper blades. It sounds like some kind of film or coating, and it could be coming from the wiper blades themselves. Does your windshield washer spray remove it?

I have not tried the washer spray. Will do that tomorrow. Clean windshield everyday to try to keep the build up. Think I will get rid of the OEM wipers.

You also may want to apply a sealant on the glass. I use Chemical Guys products.
Wash and clean window. Clay Bar (light-medium duty), wipe and clean again. Then apply a sealant using an orbital.

Yes, using a clean paper towel, then clean entire windshield with rubbing alcohol, works for me.

The mark is from where the passenger wiper stops on the driver's side and the driver's side wiper does not wipe down the mark. I have tried all the suggestions. Think I will do a new post to highlight my next question about windshield coatings to try to get some more answers.

Windshield coatings?

Well this started from the passenger wiper making a mark on the drivers side and the drivers side wiper not clearing that pesky mark. I started looking at windshield coatings. Something better than rain x since that it is not doing much. Then in the search there are products that protect against rain, snow, ice and rocks. Never thought something could do anything with rocks and I would be interested it a product actually does it. There is a gravel quarry behind me and the rock trucks speed and never cover their loads. Guess they pay off the county and do not get cited.
Anyhow, has anyone tried the windshield coatings? Which ones? How did they work?
Please do not just say 3M or Chem guys - there are still too many out there - which one in particular?
Thanks!

Sometimes I wish I had tear offs like NASCAR

Would Duragloss 755 be appropriate here? I use it everytime I apply a glass sealant to my windows, like Aquapel. I never use rainx anymore because it doesn't last that long, and yes I know you can just apply it more often.

I plan to try the glassparency. I got an application from ebay. Will pick up some bosch wipers Saturday, then do the windshield with the coating. I tried the Aquapel before - did not do much. After reading about cracks on windshields maybe I should not spend much on coatings if a pebble is going to crack it. Wonder if the hood protectors do anything with rocks from traffic.

Several folks have cautioned about hood protectors and Eyesight systems in other threads. . . .

This, but more importantly keep the windshield and wipers CLEAN

Thanks for the suggestion. I tried the glassparency - then after 15 inches of rain in the last 3 weeks it dries up. So don't know how well it work yet. I got the Bosch envision wipers (they did not have the icon in my size). Those seem to work super good. I ordered the Duragloss 755 from autogeek to try out on the Jeep.

I use a little baking soda on a small sponge to remove the film that accumulates on the out side of the windshield. It has to be rinsed but does a good job in removing the crud.

Sounds good - might even try that for the shower doors.

Ended up with the new wipers - so much better, but the wipers are fat - look like markers going past your vision.

The glassparency - can't see where that helps anymore than rain x - so that was a bust.

But used some glass cream cleaner, the glassparency, and new wipers - took care of the problem.
