Bests & Worsts Reviews from Amazon

This product was fantastic! I recommend a couple of things in using it. First, make sure you have really THICK protective gloves (not the usual plastic ones you use to wash dishes, thicker than that if possible) and wear goggles as recommended by the company. For best results apply product to dirty grout and let it sit for a good 5-10 min.(again, as recommended). No, really - go have a cup of coffee and come back! I tried both ways - I'm impatient, but found it really does better to let it soak in for few minutes before you start scrubbing. I also ordered the Fuller brand grout scrubber HEAD attachment only (not with the pole - unnecessary!!) and with this product, worked like a charm. This grout was in a very dirty bathroom that had been occupied by 3 bachelors for few years so you can imagine how gross the grout was. It looks like new! (see pics) Here's the name of the scrubber head on Amazon if you want to order it too - only $7.99 (you can screw it onto any broom pole, etc. that you already have since the head itself oscillates).
