““I just can’t believe what I see. I really didn’t believe it would work much better than anything else I’ve ever tried on my shower / spa bath. I did a few experimental squirts around the place and as I turned back to the first spots – there were white lines of cleanness. I used a fair bit to get the whole thing done, but it is clean, and it was without the hours of scrubbing I have been putting into it for so long. My Husband is not going to believe his eyes when he comes home tonight, it has NEVER been white since we’ve lived here (and he does notice and like things clean).” ”
