steel wool will take scratches out of your windshield

When I bought my car it had the wrong windshield wipers on it. I had no idea they were wrong for the car. I then went to napa to replace them and they set me up with some expensive brand. They lasted for 3 months and started vibrating while on vacation. Before I had a chance to change them one of them fell off. I finally found out that they were wrong as well and the only place I could get them on short notice was the dealer. They cost $70 and are supposed to be Bosch icons. So far they are amazing.

When it flew off......the arm scratched my windshield. Deep scratch

STEEL WOOL TOOK OUT THE SCRATCH. It also polished my windshield.

I have done this before on other cars. Works every time. It doesn't scratch the windshield.

I find very few people......even older people don't know about this. Now you know

You have structurally weakened your windshield by taking steel wool to it
When you have road debris hit the window or if you have a major collision, your windshield will no longer hold itself together and you will die a horrible death when it shatters into dozens of sharp pieces

I'm in for an answer as well. I've got a windshield with minute nicks and scratches and all the wipers I've tried chatter. On my driver side, you can see an outline that the wiper has made over time. Its not an original BMW windshield so I was contemplating swapping it out. Right now I'm using Rain-X to stop the chattering but I hate that stuff in anything but a full rainstorm.
If anyone else has taken steel wool to their windshield, I'd like to hear it, I find it hard to imagine it would work. After all, a windshield is just a piece of glass sandwiched between two pieces of plastic. I'm hoping the guy above me was just trying to be funny and didn't actually believe the windshield is now going to implode.

i'm pretty sure he was trolling you guys about the weakening thing.

would this steel wool thing be good for polishing fog lights? i have a pair of 7/10 ZKW fogs i want to polish out. has nicks.. i suspect i'd need something more abrasive like that polishing powder (cerium?)

I've used 0000 steel wool on auto glass for years. It is sort of like clay for glass: it strips off everything from the surface of the glass, leaving it smooth and, as long as it isn't abraded, nearly invisible. It is used dry, with nothing else, on dry glass. Do not use SOS or Brillo. The link in the above post is how I get mine. BTW, 8 pads will last forever for one car.

Seems to work better than chemical-based cleaners such as Windex, vinegar+water, or Invisible Glass. (IN fact, the first time I used steel wool, cleaning with Invisible Glass was a prep step.) There is never any smearing or streaking and it can be used just as easily on hot glass or cold. No need for paper towels, newspaper, or MF cloths. It does take a bit of time the first time you use it: there are likely years of build-up on the glass. But as long as you keep up with it, it is pretty quick thereafter.

I have not, however, found that it removes scratches. To be able to do that, it would have to scratch the glass itself. It does not do that. What is may have done, is remove deposits that the arm left, or cleared away deposits on either side of the track that the arm left (or some combination).

Not sure the steel wool actually removed scratches as someone else pointed out. May have removed paint transfer from the wiper blade or arm.

But the glass does get quite a bit of build up over the years on it. Steel wool, possibly a light application of the Mr. Clean Magic Eraser (be careful with the Magic Eraser, may want to test it out on an old drinking glass or jar before you get hard into your glass on your car) and rubbing compound and a buffer will easily clean and polish the glass. I have even seen people use corn starch as the final buffing powder as well. I have even seen people use sand paper to remove pits in glass fog light and head light lens. Starting with coarser paper, then moving to finer and finer grits. Not sure I would advise this on a windshield where optical clarity and lack of distortion is important.

Cerium is also the same stuff that is usually used for rock polishing as I recall. You may be able to pick up Cerium powder at your local hobby store and make it into a tooth paste consistency for deeper scratches? Cerium paste and buffing wheel may be needed for deeper scratches. But be very careful about localized heat build up when buffing or polishing glass with a lot of pressure and something like Cerium as you could have a problem with stress cracking due to uneven heat expansion. Just do not keep the buffer/polisher on the glass in the same spot with a lot of pressure for an extended period of time. Come of the glass with the buffer/polisher and let the glass cool between polishing.

I used brilo pads from the grocery store.

It was a scratch

This isn't going to ruin the structural integrity of the windshield.

Ill show that it works in a couple of days. I have an old windshield with a crack. Ill take. Knife to it and then steel wool and show the results.

Its kind of at your own risk. If yours is scratched then find a test window and try it out

DO NOT USE BRILLO,OR STEEL WOOL on your windshield.I own a autoglass and tint shop and changed alot of window's due to customer's using it.You will need cerium oxcide and a polishing wheel attached to a drill to remove fine scratche's.If yoyu can feel the scratche's with your finger nail then those are considerd deep scratche's and you will remove layer's of glass to get them out,which can result in warping your glass.My tinter uses 0000 steel wool to remove the glue off of the back window's with defogger's in order not to destroy the heater when we remove older tint when we replace it with are film.The steel wool wont take out scuff's or scratche's.

Huh?

0000 steel wool will not hurt a windshield. Agreed, it will not remove any scuff or scratch, but it does lift hard water deposits, stubborn insect and bird droppings, etc., just fine and rather quickly.
