Using an Extension Pole and Squeegee
When cleaning exterior windows up high, you can make quick work of most windows with an extension pole and a squeegee. These traditional window cleaning tools for hard-to-reach windows include a pole-mounted scrub brush that holds a large volume of window cleaning solution.
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.
Ideally, you would clean your high rise windows with an extendable water-fed pole. But if that is not available you could use a telescopic cleaning pole, glass cleaner and a drop of dish soap.
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 delete temporary files: In the search box on the taskbar, type disk cleanup, and select Disk Cleanup from the list of results. Select the drive you want to clean up, and then select OK.
Professional window cleaners keep it simple, using soapy water and a bucket, scrubber, and squeegee. Store-bought window cleaning products don't guarantee a streak-free result. Soap and water or a homemade solution leave less residue.
The most common professional window cleaning solution recipe is filtered or distilled water and dish soap. Just a few spoonfuls of dish soap is all that's needed to create foam for gliding and to help break up any grease and dirt on the glass during cleaning.
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.)
“Vinegar is a good cleaner because it's acidic, but when you add dishwashing liquid/dish soap to it (which is a base or neutral) - you neutralise the vinegar. You take away the very thing that makes it work well. “The dishwashing liquid works that well on its own. Adding the vinegar is a pointless step.”
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.
A typical solution used by professionals is 3/4 cup clear ammonia or white vinegar, 1 gallon of water and 2 to 4 teaspoons blue Dawn dishwashing liquid combined in a bucket.
Today's cleaning chemicals are just too abrasive, and they can cause corrosion and discoloration on historic metal window frames. Instead, use an ammonia-free solution and warm water to remove dirt. Do seek professional advice. Some windows are best left to professional cleaners.
If streaky windows are a big issue in your home, try cleaning them with vinegar and warm water, which should leave them sparkling and streak-free. Another option is wiping them down with a newspaper, which cuts down on streaks and produces maximum shine.
In the past, I've used a soapy solution composed of 45% water, 45% rubbing alcohol, and 10% sudsy ammonia. I can tell you this formula works extremely well, and leaves the windows sparkling clean.
Dish Soap and Water
Dish soap is perfect for cleaning windows with residue and buildup, and you only need a few drops of dish soap to get the job done. If you're cleaning inside windows, use a spray bottle and if you're washing exterior windows, use a bucket.
Fill empty spray bottle with: 1 tablespoon liquid "Jet Dry" 3 tablespoons blue Dawn dish soap Fill to the top with water, shake. Hose down widows, spray with solution, scrub all over with brush/sponge, (I use a long handled one) immediately hose off, that's it!
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 a spray bottle, combine ¼ cup of white vinegar with ½ teaspoon of liquid dish soap. Dilute the solution with 2 cups of water, then shake the bottle vigorously to mix the components. If you don't have white vinegar on hand, you can substitute it with lemon juice.
