Cleaning glass is more about the tools than the elbow grease. Even if you do exactly the right things, like mixing vinegar with distilled water and wiping with newspaper, it's possible to end up with a frustrating streak or three.
Whether you are out of name brand glass cleaner or you want to use a more natural cleaner, vinegar works wonders on windows. Try a 50/50 solution of vinegar and water for a streak-free clean. You can use a spray bottle or dip a rag in the solution, just like you would an ordinary cleaner.
Important: Vinegar is safe to use on windows and mirrors, but it can damage other materials due to acidity. Never use a vinegar cleaning solution on electronics (including on their glass screens). Don't use vinegar on granite or marble countertops or stone tile; instead, opt for a gentle Castile soap.
You can also make an all-natural window cleaning solution using a mixture of equal parts white vinegar and hot water. Adding a touch of liquid soap to the vinegar solution will help remove any streak-causing wax left on the window from commercial cleaners used in the past.
Use straight vinegar.
Simply warm 1 cup (240 mL) of white vinegar and apply it directly to glass (a spray bottle is best for this particular solution). If your windows are extra dirty, you can leave this solution on your windows to soak for a minute or two before you rinse it off.
You can also use water from a bucket. Then fill a spray bottle with white vinegar and completely saturate the glass. Allow it to soak for at least 10 minutes—longer if there's serious buildup. Next, dip a scrubbing sponge into baking soda and scrub the glass.
Using a microfiber cloth will keep your windows streak-free.
A big problem is the evaporation rate. If you're cleaning your windows on a warm sunny day, the liquid part of the solution evaporates quickly and leaves behind a residue that appears as streaks. On the other hand, if you don't entirely remove the liquid you can also be left with a streaky window.
Several homemade cleaners can work effectively to leave sparkling glass. But for convenience and safety, the simple solution of white vinegar and distilled water is the best DIY window cleaner. It's non-toxic, unlike most commercial cleaners, and versatile enough for several cleaning projects around the house.
Spray a stronger mix of 1:1 water and vinegar (or Windex, or glass cleaner) at your window, so that the solution covers most of the glass. (I found Windex to work better, but if you have pets—or kids—who frequently lick outdoor windows, vinegar may be the best route for you.)
Mix up your window-cleaning solution: In a plastic spray bottle, mix together 2 cups of warm water with 1/4 cup white vinegar and 1/2 teaspoon of Dawn. Sweep away dirt: Using a broom, sweep away the cobwebs and debris from the windows and sills.
To make the best window washing solution with rubbing alcohol, add 1½ cup water, 1½ cup rubbing alcohol, and 2 tablespoons of white vinegar (if you have any) to a spray bottle. Close the bottle, shake it to mix the ingredients, and use it to clean windows and other glass surfaces in your home.
Use vinegar
Mix two tablespoons of white vinegar to one cup of water and, either using a spray bottle or a paper towel, apply the solution to the glass. The acid within the vinegar will break down any cloudiness. It will also give a more sparkling finish to the glass.
Use soap and water, commercial glass cleaner, or a mixture of one part white vinegar and four parts water (preferably distilled water). Avoid cleaning glass in direct sunlight to avoid streaking. Start from the top of the window and work your way down.
White and distilled are types of vinegar. They differ fundamentally in their acetic acid content. White, also known as spirit vinegar, has 5% to 20% acetic acid. This is generally higher as compared to distilled vinegar's 5%-8%.
Many hotels use ammonia-based cleaning solutions because ammonia readily cuts through dirt and soap scum. Because of the way it dries, ammonia also decreases the possibility of streaks on glass.
Leave the object in vinegar and water overnight to loosen calcium deposits, rinse with water and dry with a microfiber towel. Vaseline or petroleum jelly can sometimes remove light calcium build-up. Let it sit for 4-5 days before removing.
