The '96 E320 I bought a few months back has water marks, i.e. vertical streaking, on the driver's side side windows. This streaking is quite obvious from outside but almost not noticable from inside the car.

When I inquired at an auto glass shop I was told this streaking couldn't be cleaned off and was quoted a price of $315 to replace the two windows (didn't include the little triangular one).

I then asked at the local MB dealership and was told that the streaking could be removed using very fine steel wool, but was also told that you had to be very careful and thoroughly wash the vehicle afterwards to avoid having the steel wool dust lodge and embed in the paint, then later RUST, ruining the exterior.

Anyone have any experience to share regarding trying this? Or is there some mild acid solution I could safely try that might work?

Thanks for any help.

I wouldn't use steel wool even "000". If it's water marks use some C.L.R. on a cloth that should remove the mineral deposit. Even some Bon-ami on a mosit cloth could do the trick.

Thanks for the suggestions.
Bon-ami I know of. What is C.L.R?

For those who may be interested:
I went to the market to buy a can of Bon-ami, but bought Bar Keepers Friend instead. Although non-abrasive, the B-a cautioned against use on glass, while the "slightly abrasive" BKF did not.
The instructions suggested making a paste, applying, letting sit for a 'minute', then rubbing and wiping off. I made a gruel instead, as it was windy here today and about 45 degrees (though sunny).
I experimented on the little triangular window first (about .4sf in area) and was shocked at how well this simple potion worked. I spread it on with a small kitchen sponge, let it sit for, at most, 15 sec.'s, then scrubbed in small circular motions (like waxing the exterior) for 45- 60 sec.'s. I then wiped the residue with the clean portion of the sponge and finished wiping with a paper towel and...voila! Stains gone.
It took me just over an hour to do the three side windows working smallish sections at a time - and I had to do several sections twice - but the result is quite amazing.
The can of BKF was $1.99.
I also picked up a Mr Clean 'Magic Eraser' which someone else here suggested trying to clean the vinyl on dashes, tried it on both the dash and the leather seats; and it worked very well on both. You simply wet, squeeze mostly dry, then rub gently. Two pads for $2.05, and they're reusable.

CLR is the name of a product (awesome stuff) I believe the initials stand for Calcium, Lime, Rust. Should be availble at any "box" store.

I've used the fine steel wool (paint department) on the windows without any damage to the windows, along with a product called "Diamond Magic" to remove severe waterspotting. It works.

Try a mixture of Vinegar/Alcohol/Water, in a spray bottle...it works.

i used polishing compound and scratch remover ~turtle wax ~ on my car ...... glass looks like brand new......

Clay Bar!! enjoy
