Particles stuck to Windsheild.
 

My CRV has some real stuck on contaminants on the windshield.

Really small particles (sand maybe?), but I know there are there because they are leaving “lines” and streaks behind the windshield wipers. Its not the wipers as I just replaced them.

I have washed the car plenty, and have tried simple Windex on the outside, No effect.

Two questions. I have heard newspaper is supposed to be great for cleaning glass. Would this help “polish” these particles off my windshield? If so, any techniques to share? I don’t want to leave ink streaks all over my glass.

Second, if not, is would a hand application of Autoglym windshield polish do the trick, or is there another product I should be looking at?


Thanks!

I believe there are claybars and polish specifically designed for automotive glass. I don't know how much better these stack up to a regular claybar/polish but personal experience has showed me that the regular stuff for paint doesn't work too great, unless you're removing etched in water spots.

Can you actually feel contaminants when you run your finger across the windshield? Also how many kms on the glass? Could simply be pitting or permanently etched in debris.

Steel Wool

Use a razor and scrape it.

Berz out.

Everything I have read on steel wool says it will mark and scratch the glass. Not sure if that was a joke or not, but unless you have a technique to share that doesn’t damage the glass.....

Beserker, I have used razors before to remove overspray on windows, and found that it left a few marks as well. I know it just comes down to razor angle, but as it’s the whole windshield I was hoping for something a little faster. I may have to give it a shot though.

The glass has 140K KMs on it. It sat in a tow yard beside some kind of mill for a few months before I bought it, and I think that’s where the particles came from.

Thanks for the suggestions guys, might have to try the razor route if unless anyone can vouch for the Autogylm stuff.

A fine steel wool should do the job, I get the same results as I would with a razor

blast it with piss

Right, thanks.

fine steel wool works. At the dealer we use it with cerium oxide (it's a glass polish). I've always soaked the windshield before doing it (duno if it makes a difference). Works well-- if it doesnt come off with that I dont know what will take it off.

But as above, a claybar also will remove contaminants (tried this on my own glass-- made the wipers much more clearer). Make sure you understand how to properly use a claybar though.

is there a "rate" on the steel wool i need to look for? or just "super fine"?

EDIT Looks like 0000 is the ticket. Im going to give this a shot, really worried im going to ruin the windshield, but we will see I guess.

I used a medium grade claybar...usually just the leftovers from doing the paint....it works really well if you keep up with ur cleaning.

Use with really soapy water.

000 or 0000 grade steel wool will be fine for glass but DO NOT use on mirrors. Also, razor blades can scratch the glass if you are not careful.

I use razors but you gotta be carful for you car and yourself lol

I was waiting for your reply on this.......... will try 0000 steel wool. With soapy water, yes?

Still haven’t tried it myself. As soon as I get some time Ill give it a shot.

Stupid question, but will the glass temperature make any difference? Warm glass better than cold glass for cleaning?

You can use the steel wool with water or glass cleaner. Either way is fine.

yeah, news paper does clean better. I usually use windex + newspaper
