Most of the finish damage we are asked to assess was not caused by the family walking on the floor. It was caused by how the floor was cleaned, and the damage builds slowly enough that nobody connects the two.
Never a steam mop
A hardwood floor is sealed on top but the seams between boards are not. Steam drives hot moisture into those seams under pressure, the board edges swell, and the floor cups.
Steam mops are excellent on tile and a reliable way to ruin hardwood slowly. Damp, never wet: spray the cleaner onto the mop head rather than the floor, and wring it out.
What not to use
Vinegar is acidic and dulls polyurethane over time. Dish soap leaves a film that builds into a haze. All-purpose sprays are frequently alkaline enough to attack the finish.
Oil soaps are the worst of them, because they leave a residue that is genuinely difficult to remove and that stops a new finish bonding. We have had to strip floors before we could recoat them for exactly this reason, which turns a straightforward recoat into a much bigger job.
Grit and sun, the two local factors
Sand is abrasive and, close to the coast, it comes in on everyone. Every step grinds it into the finish, and that wears a floor faster than the walking does. Mats at the doors and frequent sweeping do more than any product.
Southern California light is the other one. Strong sun fades wood floors, and it does it unevenly where rugs and furniture shade part of a room. Rotating rugs occasionally spreads the exposure, and window film on the worst-exposed elevations helps more than people expect.
When cleaning stops being the answer
If the floor is clean and still looks flat, the finish is worn rather than dirty, and cleaning harder will not bring it back.
The test: run a fingernail across a mark. If it catches, the damage is into the wood and needs sanding. If it does not, a recoat restores the protective layer without touching the wood — a fraction of the cost and disruption of a full refinish.
