I agree with Frosty. If the cement is on the glass - you don't want to do any rubbing as it will damage the surface of the glass. You can find the razor blade scrapers in the paint department of any hardware store.

If the cement is on the frame, you should be able to get it off with a soapy vinegar solution. Mix 2-3 drops of dish soap in 1 cup of vinegar (white or cider). Soak a terry cloth in the solution and gently rub on the cement. If it doesn't come off right away, let the acid in the vinegar work for a few minutes and rub some more. It should come off with minimal damage to the paint or vinyl.

Good Luck!

I would call the company that did the drive way and let them know and ask them to clean it off. If you get no results call the Better Business Bureau or the Consumer protection agency in your state. The workers should have been more careful.

Use muriatic acid. You can get it at the hardware store. It's safe and it's specificly for cleaning cement off of glass or tile.

Geez. That's a tough one but I asked my "facility" guy at work and he suggested trying to use a mild detergent and water on a paint brush. Brush it lightly and then use a butter knife with a paper towel over it to gently scrap it off. Who knows if that will work but its worth a try. Good luck.

If it's on the glass you should be able to scrape it off with a single edged razor blade. If it's on the frame, I don't have a clue. Unless you just paint over it.

razor blade and have a running hose over it while you do it.
i used to be a bricklayer and seen many scratched windows in my day from "dry" cleaning a window. concrete is way worse than mortar too so be very careful and take your time

Call the company that did the driveway... they should clean it up and/or replace the window. They're the ones who did the damage.
