I gave it a 3 star only because I don’t have the professional equipment to use it with..I used a regular electric rotary brush and it did nothing in my shower for tile/grout ..worked good when I used it as a booster for carpet cleaning though
I love grout master, and that is why I'm now buying it by the pail, because I'm running out of the regular one too fast.
It dissolves real quick in water it does the job and leaves a fresh fragrance in the area cleaned
This Grout master is the only product I will ever use for tile and Grout cleaning because it is truly the best and it’s also a fantastic booster for cleaning carpets...Game changer for sure
The product did an excellent job. The tile in question was not clean for twenty years , excellent results, I use a 500 psi portable carpet extraction machine to clean grout line . The customer was very satisfied, thank you for this product. Thanks again.
