Chemical effect on frosted glass
Permalink  
 

I cleaned a roof today with the "Apple Cider Sauce" mix and accidentally got the sauce on a storm door that was purchased from home depot. The window had a frosted glass on it. Where the sauce hit the frosted area of the window, it looked like chocolate milk or coffee was spilled on it. Any solutions to this problem, or do I just need to purchase a new glass for the customer?

Anybody ever had this issue before? Attached is a picture of the damage.

Thanks guys,

John

confuse  I would talk to a glass guy and get his opinion , maybe the process of frosting has some mineral deposits left in the glass and the chemicals had a reaction with it, theres some info on the PIPES topic about staining galvanized pipes.  I'm sure someone here will be able to help.   Vinny

That is really odd for it to have that effect.

But, try some oxalic acid mixed at 1 cup per gallon of hot water. That will possibly reverse the damage. Oxalic is sold as wood bleach and boat bottom cleaners if you don't have access to it in bulk. It's also the main ingredient in CLR. Just a few options of where you can get some. Vinegar may work, but I wouldn't count on it. The reaction should be almost instant, and don't allow it to dry.

You can also use a stronger acid, (muriatic is cheap and available)  just be sure to mix it waaaay down.

Rinse good with clean water when done.

thats weird, i would think maybe when you try to clean it again use a scrub brush so the bristle get in the frost part. maybey since its not slick like the rest of the glass it getting absorbed some how. That is just my opinion or suggestion as i heve never encounter that before. but try all the suggestions, cause what i do know is that the glass doors are like 2-300 bucs just for basic ones without all the frosting. Hope it works out.

It was probably blasted with iron particles or something like that.
