Joshua When Do You Need a Scraper?
In the following scenarios, a scraper would be required.
- Once the construction or decoration work is completed.

Checks You Should Make Before Using a Scraper Blade
Glass can be damaged by scraping it with a blade. Some types of glass are more prone to scratches than others.
- Check that the glass is resistant to scratches and can be used with Window Scraper Blades. It is not recommended that you use a scraper to remove plexiglass, crown, solar, or safety glass.
- Care instructions are provided by the manufacturer.
- Test a hidden area with a scrape before you start.
- Check the glass before starting any work and report any damage if needed.
How to Use a Scraper Correctly
- Glass scrapers should never be used on dry glass.
- Use the blade only on wet surfaces.
- This is best used with a cleaning agent that contains soap. This will lubricate the blade, and make it easier to see the area where the blade has been passed (think about it as if you were shaving your beard!
- Always scrape in one direction! Never pull back the scraper. Dirt on the blade may be pulled under the blade, causing scratches.
- Use even pressure while holding the blade flat on the glass. The edges of the blade may cause scratches.
- If the blade becomes dull, rusted or chipped, it should be reversed or changed.
- Regularly clean the blade by swishing in a bucket full of water.
- Keep your blades closed in work pouches. For your safety, always replace the cap on the blade or retract it.
Additional Suggestions
Asking the customer to sign an scratch release form is a great idea. This is a simple document that states that you will not be responsible for any scratches and that your customer has understood that there are risks involved in the job.
