I just did an estimate for a customer with 1000 square feet of Saltillo. The surface is coated however, she is having a big problem with scuff marks. When I tried to rub/remove them, they are very stubborn. They budge but only with a lot of work.

The questions are, how do I remove the scuff marks ?

                            What do I apply to avoid the scuff problem going forward??

Thanks in advance.
