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 Gary Perry

I usually take a comet, bleach or other chemical, a cleaning brush and start cleaning the shower or tub. This is really time consuming and even then I don't remove all of the accumulated scum. I've even tried a rotary brush drill and it doesn't remove soap scum that easily either. When I run my fingernail over it, the layer comes off and I feel a smooth spot. So I searched for a while for a product that could remove these deposits without putting in many hours of work. I found this and was a little skeptical that it might scratch my fiberglass, so I started very carefully. A thick layer of flakes came off immediately and I got scared thinking I'd scraped a ton of the outer layer of the shower. But low and now it was pure lather. Probably worth a few decades. So I scratched some more and thick layers of white flake material started to come off. I put a stool in the shower and put my head on the wall I was washing so she kept washing it and I didn't get wet. Just say there and scratch 15 minutes. I have to give this 5 stars because he did an incredible job removing all this debris. I could feel the build up with my fingers and it was always a lot rougher than shower tops that never get wet. After 15-20 minutes of scraping I was able to remove most of the debris and everything was smooth and even the color was better. To remove years of build up in your fiberglass shower I recommend this product. I just wanted to take before and after photos because the difference was stunning.
