Hello Partners,
Thank you in advance for your help on this one.  I really don't do much outdoor work, so I need some advice.  The photos below show the excess grout and I need to remove it.  The base is flagstone.  Normally I would try a brush attachment on my floor machine, but the stone contractor tried that and it didn't work that well.  Any help would be appreciated.


Thank You,
