Slate Floor ! Roger Konarski 19 Jul 2010 00:30 EDT

All,
I recently had a job removing a coating from a black slate floor. I finished up the job using Enrich & Seal. It was not my color enhancer of choose but it was all I had in the van that day. Anyway the homeowner calls me and they are having problem with scuff marks.  It is a small area in a high rise. What would you recommend I could use to remove the excess sealer?  I thought about lacquer thinner, but I’m concerned about the smell.
Thanks,
RK
