How do you know your floor type?
If you are not sure, check the finishing documents or ask the contractor, or try a drop of water in a hidden corner: natural marble and stone absorb water slowly and darken a little, whereas porcelain stays non-absorbent. In parquet you notice plank lines, and in laminate often a repeating pattern.
Do not rely on looks alone: some porcelain imitates marble very accurately, and knowing the real type decides the right cleaner. If in doubt choose the gentlest method: lukewarm water, a mild cleaner and a soft cloth, and avoid acids until you are sure.
