Bests & Worsts Reviews from Amazon

I do professional tile and glass restoration. I have a special go to product not available to the general public. It is pricey, which is okay when you rely on the results, but..... closed quarters use can bring about wanting to put on the respirator. Saw this, read the reviews heard the moaning about elbow grease etc. , but that doesn't register for someone who uses a Makita polisher with 3", 5" and 7" pads to wrestle off the tough stuff. If this stuff works 90% of what they were touting, then I could use my back-up stuff to finish the rest. What I want from this product is it's engineered abrasives and a bio friendly chemistry. She works... keep it wet with product until you see the soap scum and water deposit actually begin to free itself from the tile or glass. Then you can continue to let it naturally dry out as you still buff away. My first experience with this product was on a very worn outdoor tile shower with major deposits. Used 2/3 of a 20oz. bottle, that bad. I have not used it on glass yet, but from some of the reviews I have read about glass scratching, here are a few things to consider: Glass is real strong. Particulates like metal and stone or grit will scratch it though. Some folks have thin shower doors they think are glass, but they are actually Lexan, a type of plastic. Others thin glass doors are, of course tempered. Tempered glass from the orient is notorious for the cheap layer that is the tempering. There you may get some swirls from this type of abrasive. I will write a follow up when I get some glass done. Meanwhile, keep your cleaning cloths or pads real clean. Do not throw micro-fiber towels on the floor, they will pick up everything. Those small rocks and dirt will find a way to hang on even after washing. So give extra care to them.
