Just use something like Spic an Span or Mr. Clean. Using a sealer/wax will build up over time. Also it would become sticky and hold the dirt dulling your finish. I just talked to Congoleum reps about that today. They do have a polish but really don't recommend anything other than washing and drying with a towel.
