If you know the floor actually is WOOD, vacuum or sweep thoroughly first, then use a cleaner made just for wood floors. Laminate floors, which can look and feels just like wood, need a different approach, using a different type of cleaning fluid. The system I use works wonderfully well. I buy white washcloths, and they hook right onto a Swiffer mop head. When mopping I dampen the cloth first and then spray on the cleaner. I mop a smallish area and when the cloth stays white, its clean! My customers really appreciate this attention to detail, and are very happy with my results.
When the cloths start to look dingy, into the trash they go. I buy the cloths at Dollar General, and it costs about $5 for 6 of them. They are a textured washcloth, not flat. Howver, on real wood floors, I prefer using a FLAT white cloth because when you clean wood floors, you always mop WITH the grain, and using a textured cloth seems to leave marks.
