Just wondering how everyone cleans their stone pavers? Or more importantly, the grout between the pavers. We're finding it gets a little grubby and the pressure washer alone isn't doing the job. But I'm wary about using any chemicals for fear of ruining the stone. Any suggestions appreciated.
No, they haven't been sealed. The paver suggested that it wasn't necessary, in fact that it was detrimental as the stone would have a permanent "wet-look".
I actually don't know the PSI of the pressure washer as I inherited it from my father. It's a GMC, which I think is an old Bunnings brand no longer around. I doubt it is very high but it is enough to cause damage on things if you're not careful! Eg I recent tried to clean some brickwork (not very smart) and it blasted some mortar out...
If anyone else has any suggestions for cleaning products I'd love to hear them.
