Has anyone used Pure Oxalic acid for cleaning hardwater stains off windows? How does it compare to Barkeeper’s Friend? Do you have to dilute it with water, or any other special techniqes to prepare it?
Is it still alright to use 0000 Steel Wool with Oxalic Acid or BKF, or does the chemical reactions make abrasion unneccessary?
Also, is Bronze Wool Always fine enough to not scratch windows? It doesn’t seem to be graded the same as Steel Wool.
Thanks all, this is a great forum and I really enjoy browsing it and learning what I can.
I have only had a chance to use the barkeepers friend on hard water and it works pretty good. But just make sure you have wiped off everything on the glass and window sills because if you read the back label it says there is a chance to etch aluminium or other surfaces and I don’t think you want that kind of call back
Nice. How many people usually do a double take when you say that price? I mean it does need to get done so the price shouldn’t shock them that bad. And another question for you, when you go back to the same windows in say the fall or next spring you ever see the hard water coming back? Thanks!
