Clean windows provide a clear view of the outside world. They also help to decrease allergens such as dust and mold from circulating inside buildings. Professional window cleaners use a cleaning solution with a soap ingredient to ensure a streak-free shine on glass panes. This helps the squeegee slide freely without leaving behind any residue.

The first thing that professional window cleaners do is spray a glass cleaner onto each pane of glass. They usually begin at the top of the window and spray a narrow line down the center, being careful not to get any solution on the frames or non-glass surfaces. They also use a lint-free microfiber cloth rather than paper towels, which can leave behind lint fibers and streaks. They may even consider using Casabella Microfiber Glass Cloths, which have a honeycomb texture that helps to nab water spots and smudges without scratching.

These cloths are often washable and reusable, which can save both time and money over the long run. Professionals will normally do a quick inspection of each pane to check for missed spots or drips. If they notice any, they will quickly wipe them away using a dry microfiber cloth or lint-free paper towel (they will probably use the black-and-white pages of the newspaper for this).

Some window cleaners choose to add a wetting agent such as Winsol Super Slip into their cleaning solution to help the squeegee slide more freely. This can help achieve the best possible results. Some even find it useful to scrub particularly dirty sections of a window with a mild household abrasive, such as bronze wool for moderate grime or 0000 steel wool for serious grime. This is not recommended for tempered glass, however, as it can scratch the surface.

The next step is to squeegee off the window glass. It is important to work fast, to avoid letting the soapy water and smudges dry on the windows. The professionals will usually start at the top of the window and work their way down, making sure to cover every inch of the surface. Once they are satisfied that the windows have been completely squeegeed, they will again inspect them for any missed spots or drips. If they are still visible, they will quickly dry and polish the windows again to create a streak-free finish. They may also buff the windows lightly with a clean, dry microfiber cloth or paper towel.


Nothing brightens a home like clean windows. But cleaning your windows takes more than a sponge or cloth and water. It also requires a good quality squeegee. A simple squeegee has two long rubber blades with a short handle, often with a rubber non-slip coating. You can find a squeegee at most hardware or home improvement stores, and some specialty window-cleaning supplies shops. A professional window cleaner might use a more specialized tool, such as a “screen squeegee” that has thinner, thicker blades and is used to spread ink evenly over a stencil or silkscreen to create clean images on prints.

Before using the squeegee, you should wipe down the glass and frame to remove any dust, smoke, film or salt spray that may be on it. You can do this by wiping the frame with a wet terrycloth rag and then using the squeegee to wipe away any excess water that pools in the corners and edges of the window frame. A little bit of acetone or mineral spirits on a clean, dry lint-free cloth can also help remove stubborn marks and smudges. Just be sure to avoid getting the cleaning solvents on the wood or fiberglass window frames, as they could discolor them.

After you’ve wiped down the frame and window, prepare your squeegee by applying soapy water to the blade with a rag. This helps the squeegee slide more easily, and it prevents gummy streaks. Professionals sometimes add a wetting agent to their bucket of cleaning solution, such as Winsol Super Slip, which can also help the squeegee glide more freely.

Now, you can begin washing the window. Start at the top of the window and work down, wiping the squeegee often to keep it clean and free of residue. Then, dry the window with a lint-free microfiber cloth. Aim to get the glass completely dry before you begin drying the frame, as this will help prevent drips that could leave streaks on the clean glass. If you have multiple windows to wash, be sure to spray the windows as you go so the solution doesn’t dry on the glass before you squeegee it off.

Clean the Frame

It’s important to keep frames dust free. Even with regular wiping, frames collect a lot of dust and dirt. Luckily, most frames are made of materials that don’t require more than a standard dust cloth to clean. However, if a frame has a more intricate design or is made of a delicate material like plexiglass, you will want to take special care to not scratch the surface.

A soft-bristled brush and a clean, dry cloth are the best tools for cleaning the frame. Start by removing any loose dust particles with the dry cloth, and then use the brush to wipe down crevices and other areas where dust tends to collect. A cotton swab can also be helpful in reaching tight spots or hard-to-reach corners.

If the lint and dust is stubborn, you can wet the cloth with water. However, be sure to wring it out before using it on the glass. Too much water may cause stains or discolor the mat board and backing. It’s best to directly spritz the cleaner onto the cloth rather than on the glass, as this ensures that only a small amount of liquid is transferred to the frame.

Once the glass is clean, you can turn your attention to the frame itself. Generally, a microfiber cloth should get the majority of dust and debris off the frame. If you need to add more, avoid soaps that contain ammonia or any other chemical additives.

If your frame is wooden, you can clean it with wood oil to restore its shine. Be sure to let the wood dry completely before rehanging your picture frame. For a plastic or plexiglass frame, you can use a mixture of mild detergent and water to clean it. Be careful not to use too much detergent, as it can leave a sticky residue on the frame. Use a clean, dry cloth to wipe away the solution and ensure that no streaks remain. If streaks do appear, buff them away with a fresh, dry cloth until they are gone. Be sure to wipe away any excess cleaner that has pooled around the edges of the frame as well.


Whether it’s for your mother-in-law’s visit or a house showing, you want your windows to look their best. A regular cleaning schedule helps, but sometimes special circumstances call for extra care. That’s where window cleaning professionals come in. They know the right technique and materials to use for sparkling results, no matter what type of glass is involved.

The basics of window cleaning involve water, a scrubber, and a squeegee. Chemicals, such as soap and glass cleaner, are often added to the solution for additional cleaning power. Some professional window cleaners work with de-ionized water, which is a pure form of water that’s lacking in ions. This makes the water less likely to attract and hold onto solids like calcium, which causes water spots on windows. Water-fed poles, which range in length from 70 feet to six storeys, allow window cleaners to reach difficult-to-clean areas of a building, such as the top floor of an office tower.

When cleaning, always start at the top of a window, then move down. This will help ensure you’re not leaving streaks behind. Also, make sure to work in sections and overlap each stroke slightly. This will prevent the soapy water from dripping down the clean section of the window before you can squeegee it away.

Aside from using the right tools and materials, it’s important to follow the right washing techniques as well. This includes working in small sections and wiping the squeegee blade frequently to remove excess soap and prevent it from drying too quickly. It’s also a good idea to rinse and wipe your tools between sections, especially if you’re working on a larger surface or are cleaning multiple windows.

Finally, choose a lint-free towel for drying. Many paper towels leave globs of disintegrating paper on the glass, and non-microfiber cloths can deposit lint as well. Microfiber cloths are a great option because they’re highly absorbent and will leave a sparkling finish. Avoid using fabric softener on microfiber cloths, as this will coat the fibers and reduce their absorbency. If you need to, use a damp cloth to wipe off any cleaner left behind on the frame or sill.
