Casement windows should receive annual cleaning and lubrication of the moving parts to continue functioning properly over time.

Casement windows swing open and shut using various styles of window cranks and hinge assemblies. Regardless of the window design, an annual schedule of cleaning and lubricating the moving parts of casement-style windows is an important part of keeping the windows functioning properly year after year.

Step 1: Remove the screen from the window and use a soft cloth to wipe down the frame. If the screen is dirty, spray it gently with a garden hose and then wipe both sides of the screen with a mild solution of dish soap and water. Hose the screen down again and allow it to dry in an upright position.

Step 2: Crank the window all the way open and use a soft bristle brush to sweep away any debris around the frame and hinges. A quick shot of canned air can be useful for getting debris out from small nooks and crannies.

Step 3: Use a slightly damp cloth to wipe away dirt and grease from the window frame and hardware.

Step 4: Hold a rag beneath the top hinge assembly and spray the assembly and all of its moving parts with a good-quality silicone lubricant.

Step 5: Generously spray the bottom hinge assembly with silicone lubricant. Casement window operating assemblies are often recessed into the window frame. Make sure to lubricate all of the moving parts, whether they are located inside or outside the window frame.

Step 6: Spray the metal window casement track and tack guide with lubricant. Crank the window shut and open a few times to ensure the lubricant is evenly distributed along the track.

Step 7: Spray each of the window-locking mechanisms located inside the window framework.

Step 8: Remove the crank handle and clean it with a soft rag. Wipe the spline drive clean and lubricate it with the same silicone spray used for all of the other moving parts of the window.

Step 9: Replace the crank handle and check to be certain it operates properly.

Step 10: Open and shut the window a few times to ensure all moving parts have been properly lubricated.

Step 11: Wipe away any overspray. Use newspaper and glass cleaner to clean the window glass, both inside and out. Re-install the window screen.
