One of the ways on how to clean glass windows from outside is to use a window squeegee. An extendable window squeegee allows you to clean high windows from ground level without the need to climb a ladder because they can be extended to several meters.
Using your extension pole, scrub the window with your brush/sponge. Start at the top and work your way down. Rinse the window with your hose. Attach your squeegee to your extension pole and pull your squeegee across the window to remove excess water and create a polished look.
Use an Extendable Squeegee (For Cleaning)
Extendable squeegees usually have a telescopic pole handle, which means they can be used for both hard-to-reach and easily accessible surfaces. With a collapsed handle, extendable squeegees can be used on reachable interior window surfaces.
And I actually found it to be rather useful. Before getting into it, it's worth pointing out, that window vacuums aren't just for clearing condensation on windows, they also good for sucking up spills on glass and streak-free window cleaning as they have a squeegee head and onboard tank.
Step-by-Step Guide to Cleaning Third-Floor Windows:
Fill a bucket with your cleaning solution. Dip the sponge into the cleaning solution and gently clean the window. Use the squeegee to remove the cleaning solution from the window, starting from the top and working your way down.
Glass scraper: The glass scraper is useful for removing caked-on dirt and grime from the windows. Sponge or T-bar wand: Window cleaners use these tools for wetting the window with soapy water. Squeegee: Window cleaners use squeegees to wipe the dirty water away and leave behind a clean, streak-free window.
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.
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.
A squeegee. Squeegees take a little more work to get used to than cloth or paper, but the resulting difference is well worth it. On top of that, cleaning windows with a squeegee takes a fraction of the time.
The Number of Windows
This will impact the labour time and increase the final cost. If you have a conservatory on your property this could also dramatically increase the cost as it may need specialist cleaning for the glass. Even if not, the number of windows on a conservatory will add to the final price.
Scheduling yearly or twice-yearly window cleaning services is ideal. And even if that's not doable, the closer you can stick to that schedule the better. Aim for at least once a year and you'll notice a remarkable improvement.
The best homemade window cleaning solution is to just mix two gallons of water and about a teaspoon of dishwashing liquid together in your bucket. Some people also opt to use vinegar and water to clean windows. In warm weather, you'll get a little more working time by using cool water.
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.
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.
Window cleaning professionals suggest avoiding window washing on very sunny days or at a time when a window is in direct sunlight, as the heat may cause the glass to dry too quickly and cause smears.
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.
“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.”
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.)
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.
