If you get any moisture around window, I wouldn't recommend. I experienced mildew. Might try in very small spot first. Make sure dry prior to test spot. Wait about 1 week to see if test spot shows mildew. If not, then I would say yes, but from my experience, most window sills collect moisture at times from temperature differences. It will grow mildew. Best wishes..
