  • Use a window squeegee or a clean cloth to clean the window.

2nd step :

  • Wash the glass surface with the moistener.
  • Dip the moistener into the bucket containing the solution.
  • Wring.
  • Outline the surface, starting from the bottom, describing spirals and emphasizing the angles.
  • Wash the entire window.
  • Scrape off the encrusted dirt.

Step 3:

  • Scrape the surface with the squeegee, exerting sufficient pressure so that it adheres completely.
  • Wipe off the traces of water and finish with the chamoisine.

How to wipe the windows?

There are 3 scraping methods.

The French technique

The squeegee is passed from top to bottom by adjacent columns on the upper 2/3 of the glass and from left to right by one or two horizontal passages on the remaining third. After each strip, the squeegee should be cleaned.

The American technique

Less used and more technical, this method is applied by starting at the two edges of the vertical uprights and the upper horizontal upright, then from top to bottom, making S’s in the direction of the width using Raclette ; the idea being never to lift the squeegee from the surface. The moistener located under the squeegee collects the drippings as they occur. Finish with a horizontal squeegee stroke.

The Scandinavian technique

With this method, often used for windows cleaning with telescopic handles, the horizontal S’s are replaced by vertical movements starting from the top left corner and ending at the bottom right corner.
