"Really effective grout cleaner and did not require too much effort."

“Ultimate Grout Cleaner to the Max!!!!!!!!!!!

This stuff is totally awesome - I wish there was a stronger word to describe it. I used it to clean the pale pink grout on my kitchen counters, which had not been cleaned probably for a couple of years because I couldn't find your product in a store around here (Portland, OR) and it looks like brand new! Thank you for making such a wonderful product - and also for the little brush you sent with it.”
