Review on 💧 1 Quart Stone Pro Hard Water Deposit Remover for Stone and Glass Scrub by Chris Cruz

I bought this product to clean my slate shower. After three cleanings on the same area of the test tile, there was no noticeable difference in hard water accumulation. I also tested it on my sink and figured I'd leave the product (despite the price) if it helped on that surface (faux granite). nope Nada. Haven't tried it on other surfaces but if you're looking for something to remove hard water stains on any of these surfaces BUY SOMETHING ELSE. Also, the seller's return policy is definitely designed to discourage returns regardless of the reason. Combined with the price and performance claims of this product, I was very disappointed.
