I do 90% hard surface cleaning. GM is my go to and is better than any other tile and grout cleaners I have used. I sometimes get samples from other suppliers and never am I never really satisfied like I am with GM.
Even though you sell videos on your products getting s jar without instructions on use is not acceptable in my practice.
Need to use it on a nasty restaurant to see how it does. Where I’ve used it so far, I can’t tell the difference between the old stuff Im used to and Grout Master. Good product for sure, but I really haven’t given it a true test.
Everything is Awesome!!!
