I actually bough this a few months ago and because I was having a family Thanksgiving I decided at the very last minute to use it on my counter tops and islands (the day before everyone was coming). We have white tile and the grout is over 25 years old and was supposed to be white, but was very dirty and dark, even after cleaning it just a few months ago. I bought the Off White and it turned out gorgeous, my counter tops look almost new and it was a breeze to use. I have a HUGE island and lots of counters and could not believe how easy it was to use and my kitchen looks great now! One word of advice, do just a few grout lines and then wipe because it really does dry quickly and the “overflow” on the tile is hard to get off, but if you look at the video and do it the same way – no problems!
