Dear Helen:
MB-1 is a good everyday cleaner but when you really need to hit your floor a little harder, MB-2 is “your man”!
It will indeed clean your grout lines and the roughness of the stone to their pristine condition. It's a powerful cleaner and I believe that once every 6 months should do. You can use it with a brush and also with a steaming machine.
Keep in mind also that even MB-1 will perform better with a steam mop.
Finally, the sealing of the grout may make it more difficult to clean: most sealers are always a little sticky for several weeks after they applied and that stickiness traps soil more readily.
May I ask you now to please read and e-sign our Statement of Purpose at:

Ciao and good luck,
Mauri
