When it’s time to clean grime from windows, you might want to reach for an off-the-shelf chemical cleaner. However, this tends to do more harm than good, as harsh chemicals can have ill effects on exterior finishes.

    We recommend using a do-it-yourself gentle cleaning solution with simple ingredients — in addition to being budget-friendly, it’s also better for the environment. 


    Cleaning Glass

    The key to cleaning your windows is avoiding harsh chemical cleaners or abrasive tools. This prevents your windows from being scratched or damaged. You also want to avoid using a power washer or garden hose to clean your windows or doors, as the pressure can cause seal failure and result in water entering your home. 

    We recommend using our DIY cleaning solution when washing windows. Vinegar is gentle enough that it won’t harm your window finishes. Baby shampoo is also a good cleaner as it effectively lifts dirt and grease from your windows. Here’s the process we recommend: 

    1. Mix 1 teaspoon of baby shampoo with 1 gallon of water or 1-1/2 cups of vinegar to 1 gallon of water.
    2. Wash windows with the solution using a clean, soft cloth or sponge. 
    3. Rinse with clean water.
    4. Promptly dry the glass thoroughly with a cloth.
    5. Dry the frame with a separate cloth.

    After washing, be sure to promptly and thoroughly dry all surfaces. Any moisture left behind can lead to streaks or water damage. It’s best to clean your glass on a dry and overcast day, in our experience, as intense sunlight can cause streaks from the moisture drying too quickly. 

    Removing Stubborn Labels or Dried Paint from Glass

    To remove stuck-on labels or stickers from windows, first, soften the adhesive by soaking the label thoroughly with a solution of warm water and dish soap. Let the solution sit for several minutes so it can penetrate the label. Removing latex paint from glass can be done with a similar process, although the solution will need to sit on the paint for 10 to 15 minutes. 

    You can then try peeling off the residue with your fingers. If you need to, you can use a plastic putty knife to gently scrape off any remaining debris. We recommend avoiding metal blades or scrapers, as these tools could scratch your glass. 

    Cleaning Window and Door Screens

    To clean your door and window screens, you’ll need to remove them from their frames. Patio door screens lift out of their tracks. Most window screens have spring pins you can unfasten to release them. You may need to replace or repair torn window screens if you find they’re damaged. 

    You’ll then need to take your screen outside or place it in a bathtub. Rinse off the screen and then use a soft brush to gently scrub off dirt and debris. Be sure to avoid abrasive scouring pads. You should then rinse the screen completely and set it aside to dry before putting it back on the window. 

    Cleaning Exterior Finishes

    You can use the same cleaning solution we described above to scrub the exterior finishes around your windows. This gentle approach works for various materials like vinyl, wood, aluminum, and fiberglass. 

    You do need to rinse the exterior finishes immediately after washing. It’s also best to dry them right away to prevent water spots. Finally, you can apply a coat of car wax to enhance any brass or metal surfaces on the exterior of your home. 

    Inspecting Weatherstrips

    In our experience, it’s best practice to inspect the weatherstripping around your windows while cleaning them. Your weatherstripping should form a tight seal and shouldn’t be cracked, torn, or missing in spots. Gaps in weatherstripping can lead to higher energy bills due to lost insulation. Well-functioning weatherstripping prevents air leaks and helps insulate your home.

    You should also touch up any peeled exterior paint, as this will protect your window frames from moisture damage. If your windows are damaged severely, drafty, or inefficient, consider replacing them with new ENERGY STAR models that will reduce energy costs.


    So, Is Cleaning Windows Worth the Effort?

    Cleaning the exterior windows and glass doors in your home is absolutely worth the effort every spring and fall. Washing away dirt, grime, dust, and pollen restores your home’s curb appeal and allows in natural daylight to brighten rooms. Sparkling windows can make your entire house seem cleaner and more inviting.

    As an added benefit, inspecting window components during cleaning can reveal maintenance issues like weatherstripping gaps, seal failures, or paint peeling. Addressing these right away improves energy efficiency and prevents costly water damage.

    FAQ About Cleaning Windows

    Can I use newspaper to clean glass?

    Newspaper is highly absorbent, but the ink could potentially streak or smear glass. We recommend using lint-free microfiber cloths instead.


    Is Windex safe for cleaning exterior windows?

    Windex is ammonia-based, and ammonia can damage certain exterior finishes. A solution of baby shampoo or vinegar and water is safer.


    How can I reach second-story windows to clean them?

    The easiest way to reach your second-story windows is to use an extension pole for your cleaning cloth or brush. Another option is to use a ladder that is at least two feet taller than the window’s height. Always follow proper safety precautions when using ladders.


    Any tips for cleaning windows without streaks?

    We recommend cleaning your windows on an overcast day when the sun won’t cause fast drying. You should also rinse your windows thoroughly and dry the glass immediately afterward using overlapping strokes. Changing your cleaning cloths frequently can also help prevent streaks.


    Can I use a pressure washer to clean exterior windows and siding?

    No, the high-powered spray can damage glass, seals, weatherstripping, and exterior finishes. We recommend washing your windows by hand instead.
