Review on Davis Instruments FSR Big Bottle by Sam Hawj

Oh my god this product saved me a ton of money. My fiberglass shower is at least 40 years old and I've tried many products to clean it but I couldn't get the stain off the floor looked dirty and no matter what I used the old suds never came up. It was the last try! The shower looks amazing, so clean it sparkles, soapy suds, hard water and what I thought was crack covering paint was actually just a stain!
