I have known of this wonderful mixture for a few years but never took the time to find the measurements. Today I read this site, mixed my ingredients and did the windows to my back door. GUESTS ARE NOW WELCOME! 2oz Dawn Ultra with 24oz white vinegar, a plastic scrubber and a sock rag. (gonna get me a squeegee) Absolutely NO streaks! Thank you! also. . I have used Dawn on my laundry stains, forever. I am a cook and hubby is a mechanic. Any spots on our clothes get a splash of Dawn before the wash. Never fails, grease spots are gone. Cleaning doesn’t have to make us miserable! Thanks again.
