The answer to 'hardwood floor neglected' is that neglected hardwood floors can develop a dull, worn appearance over time. Common causes include lack of regular cleaning, improper cleaning methods, and not refinishing the floors when needed. Symptoms include scratches, dullness, and discoloration.
The best solution depends on the severity of the neglect. For light wear, you may be able to restore the floors with a thorough cleaning and application of a hardwood floor cleaner or polish. For more significant damage, you may need to have the floors refinished by a professional. Refinishing involves sanding down the top layer to remove scratches and stains, then applying new stain and sealant.
