Hardwood floors can be easily cleaned and maintained. It also helps in retaining the quality of the flooring for long, if done regularly. Though, an eye for prevention and routine repair measures will add to the life of your hardwood floors keeping them looking new and attractive. 
Protecting your hardwood floors from everyday wear is simple.  All you need to do is:

Vacuum – Sweep or vacuum (with a soft brush attachment) your hardwood floors regularly to remove dust particles, grit, dirt, and debris. These elements can cause scratches on the floor and dull the floor finish.

Mop – Damp mop the floor occasionally but make sure the mop is only damp and not soaked. Any excess liquid can damage the hardwood floors in the long run.

Wipe – Do not allow spills to stand on your hardwood floors. Wipe them away as soon as they occur.

Remove – Use a clean damp cloth to remove spots and stains. For tough spots, such as oil, paint, markers, lipstick, ink, tar, or cigarette marks, use acetone or nail polish remover with a clean white cloth, then wipe with a damp cloth.

Care – Cleaners and detergents with harsh ingredients can damage the finish of your hardwood  floor making it dull and faded. Select appropriate cleaners with the advice of local retailers and flooring professionals.

Refinish – Apply a buffing and refinish coat every 4 to 5 years. It aids the floors in retaining their original shine over a longer period of time.

Maintain – A relative humidity level between 45% and 65% throughout the year is the optimum temperature to minimize the expansion and contraction of wood.  Maintain room temperature for rooms with hardwood floors. Hardwoods are not suitable for areas with varying temperatures especially outdoor locations, radiant heating areas, basements, or in places which are not environmentally controlled all year.
