How to Clean & Maintain Casement Windows

May 3, 2019

Casement windows are among the easiest styles of windows to clean and maintain. Because of their functional configuration, they can be cranked open a full 90 degrees, allowing you to clean them from inside your home rather than having to get up on a ladder.

Cleaning the Screen, Glass & Frame

Beginning with the window in the closed position, you’ll want to start by removing the screen. Simply unlatch the pins around the perimeter of the screen and it should come out easily. If the screen is dirty, there are a few ways you can clean it, such as:

  • Running it under the faucet if your sink is large enough
  • Letting it soak in warm water in a bathtub
  • Spraying it with a garden hose. If you choose this option, be sure to use a moderate setting as too much pressure can damage the screen.

While the screen is soaking or drying, use a damp terrycloth towel to clean the interior frame of the window. Wipe away any dust or dirt and promptly dry the frame with a different towel, preferably a lint-free towel to avoid leaving a fuzzy residue.

While the window is closed, take your preferred glass cleaner, spray the glass, and wipe it clean using either a paper towel or a lint-free towel. Next, unlock the window and crank it open all the way, to a 90-degree angle. Just as you did with the interior, begin by wiping off any dirt or debris from the window frame. Then, reach out between the frame and the opened sash to clean the exterior surface of the glass with the glass cleaner. When you are finished, simply close the window and lock it. Place the dry screen back into the window frame and secure it in place with the pins.

Casement Window Crank Mechanism Maintenance

Aside from regular cleaning, which will help prolong the life of your casement windows, it’s important to maintain the crank mechanism by keeping it lubricated. If your casement windows are difficult to open or close, or makes a screeching noise when you operate them, they probably need to be lubricated. Use a silicone-based lubricant (not an oil-based lubricant like WD-40) and simply spray the top and bottom hinges. Open and close the window a few times to distribute the lubricant throughout the hinge assembly.

With regular cleaning and maintenance, your casement windows should continue to look and operate as nicely as they did the day they were installed. If you’ve properly applied a silicon-based lubricant but still have difficulty opening or closing your casement windows, it’s best to consult a professional window installer who can determine whether or not you are in need of a window replacement.
