Excellent product, thanks.
I’m very pleased with the GroutMaster solution. I did a white man made tile and before the grout was black. After GM everything turned white. I love this!!!
We are going to buy a full size bottle. The sample appears to have worked much better than anything we have tried before.
Love this groutmaster! We use it to clean carpets all of the time!
Works well. Thank you for the free sample. Just purchased the larger size.
