How to Clean Renewal by Andersen® Casement Windows

Casement windows are beautiful and energy-efficient windows. They can also be very difficult to keep clean. Replacement window installation company Renewal by Andersen® of Central Illinois shares an overview of how easy it is to clean Renewal by Andersen casement windows.

The Problem With Traditional Casement Windows

Cleaning traditional casement windows can be difficult, especially when you need to clean it from the upper floors. The problem lies in the hinged design: it’s easy to clean the interior side of the sash, but the exterior side, not so much, as the hinges are in the way. Some homeowners risk their safety by cleaning the windows from the outside. Grilles are another problem because of tight spots that retain dirt.

Cleaning the Window Exterior

Renewal by Andersen replacement windows are widely known for being easy to clean and maintain, among their other features. Thanks to the Fibrex® material frames and sashes, and the window coatings that prevent water spotting, it takes little effort to keep our replacement windows clean. Wash the exterior with a garden hose to remove most of the dirt and grime. For stubborn stains, use a window scrubber and dish detergent mixed with water. Use a squeegee to remove excess water, then dry with a clean cloth.

Cleaning from the Indoors

To clean your windows from the indoors, prepare the work area by clearing the area around the windows first. Cover the floor with plastic or tarp to avoid getting them wet. Prepare the sashes for cleaning by unclipping the insect screen and the removable grilles. Lift the lock lever to disengage the multi-point latch and release the sash.

This is where Renewal by Andersen casement windows differ from the rest.

"I would recommend RBA of Central Illinois for QUALITY windows and doors. Compared to our old cheap, thin vinyl windows, Andersen blows them away. You can easily tell by how well the sliding doors fit and close, and how heavy duty they are. We also cannot hear the wind rushing through the house in inclement weather anymore! And the black window frames we went with are amazing to look at. Aaron, Al, Darrell, and Cory all were professional and went all out to finish the job, given the weather they had to deal with. I would definitely recommend. They were also on top of communicating with me given the weather delays, and what I could expect for them coming out. Five stars!"
