About 3 weeks ago I used f9 barc above a window, a couple of days later customer showed me streaks on the window below.
Assuming it was from the barc I contacted F9 I then at F9 advise used a compound to restore the window. Took hours but the window was ok and customer was happy.
3 weeks later she sent me pics says it’s back?
Is this possible ?
I don’t see how this can reappear but I do see it in the pics.
She does have a broken window above this one from a golf ball I think this is what caused the rust in the first place.
cerium oxide Per F9. Low to medium speed with a pad on a drill I don’t know if it’s between the panes , but it did seem to improve when I was washing it, but could that be because some moisture got in the pains due to bad seals to make it look better? I’m out of ideas and wondering if I should call a window restoration company. I only do low pressure soft wash so I definitely didn’t damage a seal.
I also know in the picture that along the edge of the window, it doesn’t look like even etching more like a fog along the whole side so you may be right on that.
I’ve been a window cleaner since ‘96 so I just have an eye for what side a defect is on, but sometimes you can just run your fingernail across it and feel if it catches.
If you’re still in doubt, call a reputable WC company to come out and have a look.
Looks like chemical burn on the outside of the glass to me….I’ve seen it over the years. More so on “coated” commercial glass but have seen it on residential windows too. What F9 recommended is what I would have done. Sometimes you have to do it several times but be careful not to warp the glass. You could always call a glass specialist that repairs stuff like that, cheaper than replacing for sure.
Can a buffer for a car be used or is that machine too much for a window? Drill with a 3” pad takes forever.
I assume warping happens from too fast/too much heat buildup?
Any idea how much it would run to have someone restore this? It’s about 5x7 ft tall but haven’t measured. Kinda “over it” after spending hours doing it the first time.
Update:
Totally nothing to do with me or rust removal.
A Window directly above the one in question has a broken pane and the streaks originate right at the break in the glass. It most be something in there that comes out during a rain because it’s only reoccurring when it rains.
The owners are in agreement and I’m just happy. They were very understanding and didn’t try to blame me.
If you zoom in you can see that’s where it’s happening. Idk what’s in the panes these days but it definitely doesn’t come off with a standard window cleaning.
