Crb on stone ?

[Mr.cleansalot]

along time ago I scrubbed a softer stone with crb and looked to me that it damaged it so I have never tried it again .
What do you guys think or know .
Can I use one or not ?
Once my demo pads are in I can play around but til then need advice .

 

[Mikey P]

Damaged it how?

Extra stiff on polished Marble?

 

[Mr.cleansalot]

no it was more like a lime stone I'm still learning all the different stones I know the most common ones .
It just seemed to through off the look idk I only did a small area and then quit .
I could be trippen .
But don't want to chance it .

 

[Mikey P]

Hard to imagine unless the brushes were worn out and you were scratching the stone with the metal frame edge

 

[Mr.cleansalot]

No I might have been trippen .
So its all good to run blue brushes on stone ?
Do you guys ?

 

[Mikey P]

Never had an issue

As long as your brushes are not grit-impregnated, you are unlikely to cause damage. I have one Malish brush for my 175 that has (iirc) 400-grit particles embedded in the nylon. I would bot use it on natural stone, but it works well on tile and grout.
