This is a bad thing to post. It's borderline serious and someone might try it.

I have done this before on other cars. Works every time. It doesn't scratch the windshield.
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 actually used a Brillo pad on my fog lenses and they came out looking perfect. I just ran the sink water over them as I scrubbed lightly. I have the small circle OE ones though.

I used brilo pads from the grocery store.

It was a scratch

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

you can also use a razor blade at the right angle (15 degree +/-) with a lubricant to knock off burs in the glass that are common from pitting -

these burs are what cut up your wiper blades and make them streak.

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.

oooo steel wool will not hurt the glass but it won't help out his situation.He has a wiper arm scratch and need a polish.I am just trying to make a point of don't try a more abrassive steel wool.I do this for a living and been doing it for 17yrs already and my father started the business 40yrs ago so i seen alot of mistake's my costumer's have made this way.STEEL WOOL WILL NOT TAKE OUT SCUFF'S OR SCRATCHE'S

Anytime I've used steel wool to clean/detail anything I am always surprised how many small particles of it are left behind that turn to rust within a day or two. Especially when used with water you can wash those particles into areas you will never see. No thanks.

Of course, a function of how steel wool works means that it disintegrates into tiny pieces. But that isn't a big problem with windshields (one pad would suffice for a whole fleet of cars) and the "dust" is easily blown away, so no need to use water.

This has been argued on this forum here and many others. Some of the newer cars ........I wouldn't do this on because of the plastic they are made out of. This Site Is for the e46...... Not he Prius. The windows are made of glass. If you are unsure then do a test spot on glass you don't care about. Some glass shop swear by this. It worked for me to get the scratch from my windshield.

So.......ill put it this way. If your windshield has an annoying scratch right in the middle of it. Try it. If it works awesome. If not.......well, I don't know. Ive never had it not work

Get some brass or bronze wool - resists shedding, rust and corrosion (as opposed to steel wool, which can leave behind small fibers that can rust and discolor).

This. If the glass is scratched deeply enough, then the only safe, effective fix is a replacement windshield. The good news is that, if you don't have the rain-sensing wipers, the glass is not expensive.

And, if the windshield is already suffering from minor pitting (likely as the newest e46 is pushing 8 yrs old, it will seem much cleaner and be easier to drive behind, especially into the sun.

If steel wool could remove "deep" scratches, or even light scratches from glass, everybody would be using it. I will concede that steel wool can remove contaminants from glass, but call me skeptical that steel wool can remove scratches from glass. Why don't any of the detailing websites sell "steel wool to repair windshield glass?" I'll tell you why - it doesn't work. You need a product that is harder than glass on the Moh's hardness scale to cut glass. Steel is not harder than glass. Cerium oxide is harder than glass. You can buy cerium oxide kits that cut glass, but even these take a lot of work and a power buffer to remove minor scratches, with mixed results.
