Review on 🔪 High-Quality Plastic Razor Blade Scrapers Knife with Ergonomic Grip for Efficient Label and Decal Removal from Glass, Windshields, and Auto Windows - Ideal Tool for Application and Removal of Vinyl Window Tint - Includes 10 Replacement Blades by Billy Ivy

I used this to remove soapy water from my shower. I think it's best to do it dry. He removed a whole layer of soap scum that I couldn't see until I started scraping it off. Gross I know. I found it oddly satisfying and more effective than my drill brush head. My shower looks like new. Doesn't work on color stripes. This is a plastic razor blade. Great for cleaning! Highly recommended. I find it helps me clean more effectively.
