We just built a bath in our barn and had a friend tile it. The grout job was a bit messy and the tile had a texture on it. I tried vinegar, hot water, etc. etc., then saw this product demo'd on YouTube. IT IS FANTASTIC. In about 30 minutes, the shower looks fabulous, so I just brought it into the house and cleaned up tile in my laundry room that was a little smeary for 8+ years!! In fact, I stopped working on it to write this review. I'm going to tell all my house flipper friends about it. It's a MUST HAVE. Thank you!
