We just purchased a 2016 Discovery 40E we love the couch, but the floors have glue residue on them

a film I believe came from floor stickers.  These are porcelain floors and are beautiful so I do not want to

put anything on them that will dull the floor.  Does anyone else have a coach with porcelain floors?  If so,

what do you use to clean them with and what would you use to get this film off the floor.

Any help would be appreciated.
