How to Clean & Maintain Double-Hung Windows

March 30, 2026

At Tomson Window, we know that properly caring for your windows is essential to preserving their appearance, performance, and longevity. Double-hung windows are a popular choice for homeowners thanks to their versatility and ease of use, but, like any feature of your home, they require routine maintenance to stay in top condition. With the right approach, you can keep your windows functioning smoothly and looking great for years to come.


Understanding Double Hung Windows


Double-hung windows feature two operable sashes that slide vertically, improving ventilation and making the windows easy to clean. Many modern designs include tilt-in sashes, making it simple to clean both the interior and exterior surfaces from inside your home.


Homeowners in Buffalo, Tonawanda, Amherst, Grand Island, Kenmore, Clarence, and West Seneca, NY appreciate the convenience and durability of these windows. However, regular care is key to ensuring they continue to operate efficiently.


Step-by-Step Cleaning Process


Keeping your double hung windows clean not only improves your home’s appearance but also allows more natural light to enter your space.


Start by unlocking the window and raising the lower sash a few inches. If your windows have tilt-in functionality, carefully tilt the sash inward according to the manufacturer’s instructions. Repeat this process for the upper sash if applicable.

Use a soft cloth or sponge with a mild cleaning solution to wipe down the glass. Avoid harsh chemicals that could damage the frame or seals. For stubborn spots, a mixture of water and vinegar can be effective.


After cleaning the glass, wipe down the window frames, tracks, and sashes. Dust, dirt, and debris can accumulate in these areas and affect performance over time. Use a vacuum or small brush to remove buildup from the tracks.

Dry all surfaces thoroughly with a clean, lint-free cloth to prevent streaks and moisture damage.


Maintaining Smooth Operation


In addition to regular cleaning, proper maintenance helps ensure your windows open and close smoothly.

Inspect the tracks and remove any debris that could obstruct movement. Applying a silicone-based lubricant to the tracks can help reduce friction and improve operation. Avoid oil-based lubricants, as they can attract dirt and cause buildup.

Check the locking mechanisms and hardware to ensure everything is functioning properly. Tighten any loose screws and replace worn components as needed.


Protecting Seals & Weatherstripping


The seals and weatherstripping on your windows play a critical role in energy efficiency. Over time, these components can wear down or become damaged.


Inspect the weatherstripping regularly for signs of cracking, peeling, or gaps. Replacing worn weatherstripping can help prevent drafts and maintain indoor comfort, especially during the colder months in Western New York.

Keeping seals intact also helps protect against moisture infiltration, which can lead to more serious issues if left unaddressed.


Seasonal Maintenance Tips


Each season in Western New York brings different challenges for your windows. In the spring and fall, take time to perform a thorough cleaning and inspection. This helps prepare your windows for temperature changes and verifies that they are functioning properly.


During winter, monitor for condensation or frost buildup, which can be signs of issues with insulation or humidity levels. In the summer, check for expansion or warping caused by heat and address any concerns promptly.


Routine seasonal care can extend the lifespan of your double-hung windows and improve their overall performance.
