Famous Heloise window glass and bathroom cleaner formula is a winner

My grandmother rarely used commercial products for cleaning windows, glass shower doors and mirrors, and soap scum on tile walls around the tub. She used something she called her Heloise Formula: one cup of white vinegar, one U.S. quart (or one liter) of rubbing alcohol, one tablespoon of dish-washing liquid, and two and a half quarts of water. Grandma kept this mixture in a large jar which she used to re-fill an empty spray bottle. She never used newspaper to wipe her windows dry, preferring to use brown paper towel sheets. Apparently the black ink on newspapers kept her windows from sparkling. I use this cleaner myself and it works quite well, and it doesn’t have that perfume smell that you get with commercial cleaners. If you have a natural marble or granite counter top, don’t use this formula. The acidic vinegar could etch the surface. Consult your local hardware store for marble/granite cleaners.
