It's a good video but I don't live in California. I live in West Texas and I'd love to know what chemicals you're using. My Saltillo tile has water damage, very dirty grout and dark marks. Approximately 3904 square feet that needs to be donel. The contractor I hired didn't bother to clean it first and just filled up the floor machine with ZEP, and it's really messing up the floor, they look terrible!
