I just wanted to tell you how happy I was with your product. I found you on the internet and everyone told me it wouldn’t work. It was too good to be true. But to my surprise! It did work. I cleaned and sealed my tile in my bathroom shower. It is about 5 years old and the grout would not clean up like it did when it was new. I had tried all kinds of different products and they didn’t work. I thought your product was so reasonably priced that it was worth a try. Thanks for a great product that does exactly what it is represented to do.
