residue removal from exterior windows

I did windows the other day and had a hard time removing some kind of residue on the window exterior. The home owner says he has in the past with great difficulty removed the residue with a razor. i tried the razor by wetting the glass then scraping but no good. I tried ajax with a scrunge sponge and it didn't work. I windexed and dried and it was still there. What is this stuff RAIN Minerals? I have no clue. what do I use to restore these windows?

Thanks,

try using some vinegar on the spots, if it is mineral based (as in water spots or even stucco residue) the acidity of the vinegar should help to remove it

cleanig residue

You can also use a concentrated glass cleaner. Make sure you dilute it before applying it to the affected spot.

It sounds like hard water spots.
If the vinegar doesn't do it you'll have to step up to Safe Restore or a paste compound.

Glass restoration is a big job, not part of regular cleaning, and should be charged for accordingly.

Clean the exterior area that needs to be caulked removing old caulk, dirt, old paint, or other debris. Make sure the surface has no dust or residue left on it that may effect how the caulk sticks and dries.

This pretty much solves your problem. I do agree with charging extra for glass restoration since it's not an easy task and is rather tedious too.
