Whether it's at a new construction site, or at an existing home, windows that are near the construction activity should be covered with clear plastic to protect them. Building materials such as concrete can easily get splattered on the glass. Concrete can be especially hard to remove because of its strong adhesive abilities. Fortunately, there are two methods to remove concrete. The first way is relative easy because it involves wet concrete. The second way is more complex because it's used after the material has hardened.
To Remove Wet Concrete From Windows
Spray the windows with plenty of water to loosen and remove as much of the concrete as possible.
Wet a sponge with water. Wipe over the glass to remove any remaining splatters. Spray the windows as you go to clean them. Keep the sponge and the windows constantly wet so the glass doesn't get scratched.
Clean the window with glass cleaner and paper towels after all the concrete has been removed.
To Remove Hardened Concrete From Windows
Read and follow the manufacturer's directions and warnings on the concrete remover. Wet the glass with a garden hose.
Dilute the remover with water if necessary. Apply the product to the window glass. It will likely be from an aerosol can, by using a low-pressure foaming system, a sprayer, or by brush and bucket.
Allow the concrete remover to set for the amount of time the directions specify. You may need to lightly moisten it during this time so it doesn't dry out.
Brush over the loosened concrete splatters to remove them. If necessary, use a razor blade to carefully scrape off stubborn spots.
Spray the cleaned windows off with a garden hose. Clean them with glass cleaner and paper towels.
