Cleaning Instructions

It is easy to maintain the beauty of your windows.

Cleaning Instructions for Alpen WindowsAlpen Windows and doors are virtually maintenance free. However, as with any product exposed to atmospheric conditions, they will become dirty and require cleaning. With very little effort your windows and doors will retain their “just new” look for years to come. In most cases, exterior dirt and grime will wash away during the next heavy rain storm. However, if Mother Nature is unable to clean your windows, follow these guidelines.


Most severe window accidents occur on the first floor. If in doubt of precautions and dangers, hire a licensed, and insured professional window cleaning service.
