First time that I’ve ever seen 0000 steel wool scratch.
And… Fabricating debris so bad you can see it. If you look around the light you will see a few sparkles. Thats just what the camera could pick up. It was very visible throughout that entire pane when looking at the light.
Was it you or a other company who made the scratch? I guess very old windows?
It was me that scratched the glass ( busted out glassrenu kit and fixed it). It was brand new glass with no scratches at all. I cleaned it, then touched up some silicone finger prints with steel wool and that happened right before my eyes. First time I’ve seen it scratch
I haven’t yet have a scratch with 0000 wool. Scary 
Before today I was on the “it won’t scratch” bandwagon but now I’m on the “be careful” side
Hmmmm… wonder what made the scratch on this window, this time…
Naw, just look for the Old Castle seal. OId Castle, when you absolutely positively have to have The Worst Glass.
Im cautious when use #0000 it has scratch glass for me in past, @DaveYogi has experienced the same thing.
Just use with caution.
Ive used steel wool once or twice . I’ve never had a scratch . But I always suggest being careful…
Old Castle is not worth doing much more than scrubbing with a saturated mop and squeegee. Even then you might detect a few scratches. For those silicone marks use Magic Eraser instead.
Was this stupid winow cleaner
Got tagged about 0000 steel wool.
When I was 17 my boss called me the "steel wool king’.
I was taught that steel wool was the correct tool to detail glass post cleaning. I did as I was taught.
20 years later. We will have 0000 steel wool in the shop, it was at a new construction jobsite yesterday.
Tried bronze wool, white pads from WCR, white pads from others, scrapers, whale vomit and tiger piss.
I will say this. I 100% know/believe that a brand new piece of 0000 steel wool can result in micro scratches.
I am not a scientist not into attempting to be. I have seen it, I have heard it, more importantly I fucking live it. I think of this for a micro second daily while I drink coffee and curse at hippies
I hear “anderson” this and “pella” that.
What I can say. Newcastle, IN MY AREA, seems to only be used for interior doors. By the time I get to them they are scratched to hell.
Not my problem, but I do warn every new hire of New Castle products
Actually, the only ones I haven’t had problems with are Pella. Great glass, but sometimes the design is stupid - old designer series come to mind.
I agree…
West coast vs east
Tupac vs Biggie
I do not deal with storm windows vs my pals on the East who do weekly
Really? I’ve ran into issues with their glass.
Anderson glass seems to be best around here, in my opinion.
I’ve seen 0000 wool scratch all types of different glass.
That makes me worried. That wool have been my best friend many times…
That’s interesting. I’ve had the exact opposite experience. Andersen uses ‘self cleaning’ coatings extensively on their low-e windows, which makes them far harder to clean.
I’ve also noticed some type of “inclusions” on their older annealed glass. It sounds kind of like fabricating debris when you scrape it, but it’s not tempered. Nicks up my blade something awful, and scares the heck outta me. (@Henry wrote something about this in his ghost particle series).
Pella seems to be pretty solid. Some of the designs are a little wacky, but the glass seems good. You do have to watch out for the hardcoat low-e in some of their storm panels, but it’s a lot easier to spot than a self cleaning coating, and less likely to get stubborn junk on it.
