I’ve heard white vinegar will take off hard water spots. Seems a little less risky too.
That is what it’s called and I keep it. Glad I’ve never had to use it.

Oh that’s good most folks don’t have that.
That coverage was like $10 more a month for three stories and less. Why not?

Alex … Have you ever used one of these. Would it be good for Screen oxidation?
Man I have to find something good for this. One restore works unreal for it , but if I could find something better that would be awesome.
@Henry how much are these things An were can we order it ?
Do they work with any drill ? Or do yuh need a buffer ?
I have not. Only saw a brief video demo he posted once, but I loved the concept. Not sure if he has any left?
I use sodium hydroxide on screen burn. Usually in the form of oven cleaner. But I don’t use it often.
Yes I know the old time window cleaners used oven cleaner. Never tried it. !
So sodium hydroxide is F18
Right ? This works good ?
I just bought a chemical for gutter whitening that I never used yet That I herd about. I think it’s cslled cleansol BC. forgot the name I’ll look when I get home. I’ve been wondering if that would work on screen burn. It’s not as toxic as F-13 gutter grenade.
Very interest about the Sodium hydroxide though. What was your procedure ?
These metal screens drive me crazy this past year. It’s very frustrating. I know how to sell it to the customer , but I feel bad. Most don’t want to pay what I want to do the job so they just leave it. If I can find a method as easy as the one restore without the risk I’l be very happy I can lower the price s little an feel a little better when j leave the job.
Tejbir, welcome to this fine site. I looked you up and went to your web site; man, beautiful pictures. Seems like you do great work. Chemical work is a whole different animal. Now, in my area, there are companies that specialize in replacing storm window glass. The guy came on site, pulled the picture window, replaced the glass and reinstalled the double pane back into the picture window. Looked brand new, but just the glass was replaced, not the whole window. You might do some looking in your area for glass replacement companies and get a good quote; instead of replacing the whole windows. Sorry you had this happen. Check your area for glass replacement companies…see what happens. Hopefully customers are willing to work with you on some options instead of total replacement. 12-15 hundred probably doesn’t include labor, and it may be difficult to match what they have now. Walking through this, one step at a time will give you some hard earned education and experience. Hang in there, learn from your mistake.

Thank you LoveGlass for the advice and positive wisdom. I started a window cleaning business that is professional, reliable, and always provides excellent service. I intend to stay on that path, gaining experience through the ups and downs, like you said - one step at a time. I’ll look into what you suggested. I also appreciate everyone’s help so far and it is great to find this forum to connect with others. Stumbling into the window cleaning business has been such a blessing.
I’ve used OneRestore @ 2:1 concentration a bit more frequently the last few years because it works so well, but you have to get it rinsed off quick. I’ve had some badly stained windows and I would spray a few windows and then go back and clean them in order, but I was finding on certain windows it was just too much contact time. You could definitely see where the chemical was sprayed on and ran down the glass. It seems better to spray it on, immediately use a scrub pad to even out the application, blade the heavy build up off, and get it rinsed off quickly.

What Chris said. Tin etch haze. If the tin side of the glass is exposed the acid in One Restore will react with the tin and etch the glass.
My experience has been it doesn’t matter how long it is on the glass if the tin side is not exposed. I have left it on in the sun and went to lunch and came back and cleaned it off with no issues.
If the tin side is exposed then yes thenlongernit dwells the word it will etch.
You can tell if the tin side is exposed by using a black light. Shin it on the glass and the color will differ from the non tin side.
Weaker acids like vinegar will remove some tyoe of mineral deposits but won’t remove silicate deposits and neither will One Restore. You have to use CC550 to remoce those which will have a much stronger reaction with the tin side.
As you discovered the alternative (cerium oxide) has its own risks which is swirl marks. It’s a process learning to use it.
Most guys who have asked me for help on similar jobs locally I have told them juat to bite the bullet and replace the glass if it is a small ammount of glass. It will cost you more in time and effort to learn restoration than it will be to just replace the glass.
So the whole solution to using Acid On glass is to make sure your not using it on the tin side… Yes ?
You have one of those lights, if so do you like them ?
Yes. It’s just a black light.
