To avoid drips and evaporation, spray Windex® Glass Cleaner on large windows in sections, wiping away the cleaning solution before moving on to the next portion.
Have you ever spent hours washing your windows, only to notice streaks everywhere? 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.
It's often recommended to spray the window cleaner directly on your microfiber cloth, newspaper, or t-shirt instead of the glass. The reason is that this will help you avoid drips that can leave streaks if you don't wipe them up quickly. You also need to be more careful with windows and mirrors with wood frames.
For best results, avoid using Windex® Original Glass Cleaner on very hot or cold surfaces. The product may evaporate before wiping and cause streaking. Choosing the right towel can also help achieve a streak-free shine.
If you're all about the DIY life, we've got just the thing for you. 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.
Wipe off any excess cleaner to prevent streaks
You can use a squeegee for a streak free finish. Also work in an S-shape. Periodically wipe the squeegee blade on a clean rag to avoid smearing dirt around. Remove remaining water with a damp chamois or microfibre cloth and dry the windowsill.
You'll have plenty of time to catch the drips. For cleaning smaller surfaces, Windex® Original Wipes achieve a streak-free shine in a spray-free format.
Smears and streaks on windows are mainly caused by watermarks and areas where cleaning solution has remained on the surface – this is down to excess moisture not being absorbed when wiped away. Window cleaning products will say that they are streak-free, but it is not that simple.
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. This is often seen on windows that are hit by sprinklers or ground water, although there are some areas that have hard enough water inside to look this way as well.
Another glass-cleaning recipe calls for 1 cup (236 milliliters) of water mixed with 1 cup of rubbing alcohol and 1 tablespoon of vinegar (rubbing alcohol also prevents glass streaks) [source: Aguirre]. Similar to standard cleaners, vinegar water comes with its own aroma.
Provided they are clean, microfiber cloths are the best way to avoid thin films left over after you wipe down the surface of your glass or mirror. Some people recommend using rags, or an old tee-shirt, but those materials were not designed for cleaning.
It contains vinegar and isopropyl alcohol, which both cut through grease and kill bacteria. Simply mix one cup of alcohol and water and add a tablespoon of vinegar. Add the mixture to a spray bottle, and you're good to go! This cleaner works on any glass surface, from your windows to the lenses in your glasses.
For best results, make sure you completely rinse suds. Do not allow product to dry before rinsing, rinse windows from top to bottom and use Windex® Outdoor Sprayer when the temperature is above 55º F. If the product is applied to eaves or siding above windows, it may drip down on windows.
The best time to schedule window cleanings depends on where you live and how susceptible your windows are to getting dirty. Generally, window cleaning should be done at minimum once or twice per year, plus on an as-needed basis, including at least one cleaning of any window screens.
Perhaps your windows haven't even had the dirt removed properly. This can happen if you keep reusing a sponge that isn't being washed frequently. Or if the technique used is sloppy and not thorough. And some squeegees give a really patchy finish, especially poorer quality models not designed for professional use.
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.
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.
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.
More environmentally-friendly than disposable paper towels, a microfiber cloth has numerous other benefits that make it an ideal alternative for cleaning windows and surfaces: Absorbency: A microfiber cleaning cloth absorbs over six times its weight in water and when used dry, collects fine dust through static charge.
