Review on Grout-Eez Ultimate Grout Cleaner: Effortless, Powerful, and Safe for All Grout Types. by Bob Berry

This product was fantastic! I recommend a few things about using it. First, make sure you have really THICK protective gloves (not the usual plastic gloves you use for washing dishes, thicker than those if possible) and put on safety goggles as recommended by the company. For best results apply the product to the dirty solution and leave for 5-10 minutes (again as recommended). No, go have a coffee and come back! I've tried both ways - I'm impatient, but I really found it best to leave it on for a few minutes before you start brushing your teeth. I also just ordered the Fuller HEAD brand scrub head (not with the stand - needless!) and it worked like a charm with this product. This grout was in a very dirty bathroom occupied by 3 bachelors for several years so you can imagine how disgusting the grout was. It looks like new! (see photo) Here's the name of the mop head at Revain if you want to order it too - only $7.99 (you can bolt it to any broom etc you already own as the head itself wobbles).
