Let's Get Started

To clean and care for your casement or awning windows, either follow the directions in the YouTube® video or see the linked written instructions below.

Care and Maintenance for Casement, Awning, and Gliding Windows

Clean Glass

For written instructions on cleaning the glass, see, Clean Glass, Aluminum, Vinyl, Fibrex®, and Fiberglass Surfaces on Andersen® Windows and Doors.

Check Hardware Screws

Hardware screws, especially hinge screws, should be periodically inspected and tightened if necessary. Over time, wind can impact the sash, loosening hardware fasteners.

Clean Hardware

An excessive buildup of dirt, dust, and debris on the operator, hinges, or locks can affect the product's performance and make it hard to open and close. For written instructions on cleaning the hardware, see Andersen® Window and Patio Door Hardware Care and Maintenance.

Important:

• The use of harsh abrasive cleaners is not recommended and can cause damage.
• Do not attempt to refurbish hardware. Instead, contact a professional hardware restorer for refurbishing.

Lubricate Hardware

After cleaning, lubricate moving hardware parts with a dry silicone spray. For written instructions on lubricating the hardware, see Lubricate Andersen® Window and Patio Door Hardware.

Important: Liquid spray lubricants, including those with acetone, and oil-based lubricants are not recommended.

Adjust Casement Window Sash

Periodic window sash adjustments can keep a casement window operating smoothly. Depending on the casement window series and operator type, you may be able to adjust the window sash. See Sash Adjustments for Andersen® Casement Windows for more information.
