The Ultimate Window Cleaning Guide: Tips and Techniques


Crystal Facilities Management is dedicated to providing top-quality cleaning services to our valued customers. One area that often requires special attention is window cleaning. Sparkling clean windows not only enhance the overall aesthetics of a space but also allow copious amounts of natural light to flood in. In this ultimate window cleaning guide, we will share some invaluable tips and techniques to help you achieve crystal-clear windows that will impress all who see them.

Gather Your Supplies

Before embarking on your window cleaning journey, it’s important to ensure you have all the necessary supplies at hand. Here’s a checklist of items you’ll need:

    • Microfiber cloths or lint-free towels
    • Squeegee
    • Bucket
    • Dish soap or a window cleaning solution
    • Vinegar or ammonia (optional)
    • Old newspaper or coffee filters (for streak-free finish)


Preparation is key to a successful window cleaning session. Follow these steps to prepare your windows for cleaning:

    1. Remove any loose dirt or debris from the windows using a soft-bristled brush or vacuum cleaner attachment.
    1. Close the windows and secure any latches or locks.
    1. Cover the surrounding areas with towels or plastic sheets to protect them from potential drips and spills.
    1. Ensure your ladder or step stool is stable and secure before climbing up to clean higher windows.

Techniques for Sparkling Windows

1. Cleaning Interior Windows

Follow these steps to clean the interior side of your windows:

    1. Fill a bucket with warm water and a small amount of dish soap or a designated window cleaning solution.
    1. Dip a microfiber cloth or lint-free towel into the soapy water.
    1. Starting from the top corner of the window, wipe the entire surface in an S-shaped motion. This will help prevent streaking.
    1. If necessary, use a squeegee to remove excess water from the window, working from top to bottom.
    1. To achieve a streak-free finish, buff the window with a crumpled piece of old newspaper or a coffee filter.

2. Cleaning Exterior Windows

Cleaning exterior windows often requires a little more effort due to built-up dirt and exposure to the elements. Here’s how to tackle them:

    1. Follow the same preparation steps as for interior windows.
    1. Add a small amount of vinegar or ammonia to the warm water and dish soap mixture in your bucket for added cleaning power.
    1. Dip a microfiber cloth or lint-free towel into the soapy water and scrub the exterior of the window, paying extra attention to stubborn dirt and grime.
    1. Rinse the window thoroughly with clean water.
    1. Use a squeegee to remove excess water, starting from the top and working your way down.
    1. For a streak-free finish, buff the window with a crumpled piece of old newspaper or a coffee filter.

3. Dealing with Stubborn Stains and Spots

Occasionally, windows may have stubborn stains or spots that require extra attention. Try these techniques:

    • Mix equal parts vinegar and water in a spray bottle. Spray the solution onto the stain and let it sit for a few minutes before wiping it away with a microfiber cloth.
    • If the stain persists, make a paste using baking soda and water. Apply the paste to the stain, gently scrub it with a soft-bristled brush, then rinse it off with clean water.
    • For particularly stubborn hard water spots, dampen a cloth with white vinegar and lay it over the affected area. Leave it for a few minutes, then wipe away the residue.

Maintaining Clean Windows

To ensure your windows stay clean and clear for as long as possible, consider the following tips:

    • Regularly dust and wipe down window sills and frames to prevent dirt build-up.
    • Avoid cleaning windows on hot, sunny days, as the cleaning solution may dry too quickly and leave streaks behind.
    • Consider using window film or applying a protective coating to make future cleaning easier and prevent stains.
    • Establish a regular window cleaning schedule based on your location and environment. Windows in urban areas or near busy roads may require more frequent cleaning.
