Don’t Use Razor Blades on Your Windows!
Window glass MUST be lubricated BEFORE using a razor. Most professional window cleaners will typically use soap and water to lubricate the glass which helps minimize the occurrence of scratches. It is also important to note that razor blades cannot be used on treated glass surfaces such as tinted or mirrored window glass. Special care must be given when working on tempered glass and heat strengthened glass, which is commonly found in doors and high impact area.
Here are a few more tips to consider:
• Only use a professional grade glass scraper
• Start each project with a new blade
• Replace blade when marred or dull
• Test razor in an inconspicuous place before scraping entire surface
