The best way to keep wood floor looks shiny is by sweeping and moping it all the time. Spray the mop with wax so that when you mop, you are cleaning and polishing at the same time.
It is best to mop it at least once a week. Ensure the mop is not too soggy to avoid water absorbed into the wood. That absorption will only make the wood bent.
Detergent in general is too strong for wood floor.
1. It is better to use a mixture of:
  1. A half cup of vinegar.
  2. Four liters of water
2. Soak the mop into the mixture.
3. Wring out until dry.
4. Scrub over a small part of the wood.
5. Replace the mixture if the mixture gets dirty.
Remove heel marks with oil or eraser.
Remove scratches by softest steel wood pad which had been soaked into floor wax.
Brown shoe polisher mixed with floor wax could be used to shine the dull-coloured part.
