How to care for finished concrete floors
 

I rent a building that has finished concrete floors. Customer foot traffic has really scuffed them up. My lease on this building is coming to an end and I am getting ready to move my store. I'd like to know how to clean up these floors, remove the scuff marks and get them nice and shiny again so I can get my entire deposit back. I appreciate and suggestions. Thanks!

Rent a buffer to clean them up. Apply a fresh coat of concrete sealer.

...and finish off with a floor wax.
 

...since you've already rented the buffer.
