Combine two parts water with one part white vinegar in a spray bottle and you'll be all set with a homemade window cleaner. You can also combine warm water with a few drops of dishwashing soap if you prefer. Invest in a glass spray bottle to mix up your formula.
Odd though it might seem, wiping down glass with newspaper not only helps produce streak-free glass, but also a lovely, bright shine! Be sure to spray your cleaning product on the newspaper or cloth rather than directly on the mirror. This will prevent the cleaner from dripping into the frame and possibly corroding it.
Professional window cleaners use a solution made from dish soap and water to achieve a streak-free clean. The key is to use a small amount of soap and distilled water. Some professionals add ammonia to the water for increased cleaning power.
Using isopropyl alcohol and white vinegar together makes a quickly evaporating spray glass and mirror cleaner that competes with commercial brands. This can also be used to give a nice shine to hard tiles, chrome, and other surfaces.
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.
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.)
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.
You can use Windex® Ammonia-Free Glass Cleaner on your vehicle's tinted windows, mirrors, glass, chrome, stainless steel, plastic, and vinyl surfaces. For a streak-free shine, clean car windows when the surface is cool and out of direct sunlight whenever possible.
Squeegee the windows
The dry edge creates the perfect surface to get a good start and you don't have to be up against the window edge and causing missed spots. There is little to no cleaning up leftover drips from the squeegee when you use this method making it much faster.
The blue solution in the reservoir is an alcohol-based glass cleaner probably diluted with some water. After multiple people have wiped bugs, mud, oil, and gasoline off their vehicle using the squeegee and dunked it back into the tub, that fluid is more filth than detergent.
Instead of using standard cleaning products, get a bucket of water and mix it with dishwashing detergent or vinegar. Apply this cleaning solution to the glass using a long window scrubber. Grab a squeegee and pull its blade over the glass in a reverse “S” pattern.
This has to do with the evaporation rate—if your cleaning solution evaporates before you have time to wipe it off, it will leave a mark. Alcohol- and ammonia-based cleaners evaporate more quickly than vinegar, but any window cleaner can leave streaks if it isn't removed fast enough.
Paper towels are an easy go-to whenever you're cleaning glass. But, that right there is your problem. Paper towel is the number one culprit of leaving behind streaks and lint. Paper towels are typically treated for absorbency, which makes them ideal for spills, but awful for glass cleaning.
In many areas, hard water is the cause of bad streaks and stains on glass. Salt and other minerals in the hard water might look clean as you wash the window, but once dry it becomes a white streaky mess.
The dish soap helps to soften up the grime and gently remove dirt. Generously mist the solution over the surface of the window, and allow it to sit on the glass for a few minutes. Wipe off the window in a large circular motion using a lint-free microfiber cloth, newspaper, or even coffee filter.
Vinegar. A trusted way to get windows sparkling is a combination of water and vinegar. Fill a bucket with water and add two or three cups of white vinegar.
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.
For most windows, combine equal parts distilled water and white vinegar. In most cases, it's best to do this in a spray bottle, but for larger windows combine more liquid in a bucket. For very dirty windows, especially exterior windows, combine 2 cups of water, 1/4 cup of vinegar, and 1/2 tsp of dish detergent.
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.
Mix one part distilled vinegar to 10 parts warm water in a spray bottle. Wipe down the window with a a soft, clean, lint-free microfiber cloth or paper towel to remove dust before you spray your solution, then spray the entire surface.
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.
