Here are some tips for maintaining wooden flooring:

Sweep or vacuum regularly to remove dirt and debris.
Use doormats at entrances to prevent dirt and moisture from being tracked onto the floor.
Use protective pads under furniture to prevent scratches.
Wipe up spills immediately to prevent staining.
Use a damp (not wet) mop or cloth to clean the floor. Avoid using too much water, as it can damage the wood.
Avoid using harsh chemicals or abrasive cleaners on the floor.
Use a wood floor cleaner specifically designed for the type of wood and finish on your floor.
Reapply wood floor finish every 3-5 years to protect the wood and keep it looking fresh.
Consider using rugs in high-traffic areas to protect the wood and reduce wear and tear.
