a mild acid is probably the best way. If the window is wrapped in aluminum, use vinegar, straight from the bottle. It may take a few applications but the bubbles indicate that the acid is cutting the minerals in the concrete. If the window ISN'T wrapped in aluminum, you might try a WEAK solution of muratic acid. Mix with water, using about 3 parts water to 1 part muratic acid. When working with murtic acid, make sure you use eye protection (preferrably a face shield), long sleeves, rubber gloves and have water close to wash off any mixture that splashes on your skin. Also, any cloths you wear will be destroyed so pick something that you plan to throw away.
