Precision Foam Scraping

What happens here

Once the initial wiping has been performed, take a two-edge knife (or a similar scraping tool, like a painter's knife or utility scraper). Position the blade carefully against the dried spray foam on the window glass and the adjacent frame. Apply only light pressure while scraping to avoid scratching the window glass or damaging the frame. The video emphasizes using "just light scraping so I'm not scratching the windows." This method is used to remove the bulk of the "dried a few service" foam.

Goal: Remove the main layers of dried spray foam without damage.
