The answer to 'how often to clean hardwood floor' is that most experts recommend cleaning hardwood floors every 1-2 weeks. This helps maintain the appearance and condition of the wood. Regular cleaning removes dirt, dust, and debris that can damage the floor over time.
For high-traffic areas, you may need to clean more frequently, such as once a week. In less-used rooms, you can usually get away with cleaning every 2-3 weeks. It's also important to do a more thorough cleaning every 6 months to a year to deep clean and protect the wood.
