6 Life-saving Tips for Scraping Windows


Scraping windows with a window scraper can either increase your effectiveness or cause you more costly problems.  Scrapers are great for removing stickers and most stuck on debris giving you problems and not coming off with just your washer.  But they can also damage windows if used incorrectly.

Important Note: Be extremely careful when scraping windows.  Incorrect method can result in costly damages.

Proper preparation and technique are important.  Here are some tips that can save you time, money, and headaches.

1. Beware of Tempered Glass

Tempered glass or safety glass is a hardened glass that can scratch easily due to the likelihood of raised imperfections formed in the hardening process.  You should never use a window scraper on tempered glass, as it will scratch the glass as you run the blade over those imperfections.

Beware that scratches caused to tempered glass may not even be visible until 45+ minutes later, as these scratches can grow over time.

2. Use a Window Scraper

Always use a professional window scraper for scraping windows.  Don’t use household items like flat-head screwdrivers, box cutters, putty knives, etc.

3. Inspect Your Scraper

Always inspect your scraper before scraping a window.  Make sure there is no rust, chips, or bends in the blade before starting.

4. Wet the Window

Always wet the window before scraping.

5. Test a Small Area

Test the scraper on the window in a corner before using it on the window.  Make sure there are no scratches.  And remember that some of these scratches may not appear right away.

6. Scrape in a Forward Motion

Only scrape by moving the scraper forward, like a plow.  Side-to-side or even pulling the blade backwards back over the glass can cause scratches.  Debris can get trapped under the backside of the blade.  This is also why you should only scrape small sections at one time.

Keep these tips in mind and you should have a more productive and less costly time of scraping windows.
