The answer to 'DIY hardwood floor cleaning' is to use a mild, pH-neutral hardwood floor cleaner and a microfiber mop. Start by sweeping or vacuuming the floor to remove any loose dirt or debris. Then, mix the floor cleaner with water according to the manufacturer's instructions. Dip the microfiber mop into the cleaning solution, wring it out until it's damp but not dripping wet, and gently mop the floor in sections. Avoid excessive water, as it can damage hardwood floors. Rinse the mop frequently and change the cleaning solution as needed. Allow the floor to air dry completely before walking on it.
It's recommended to clean hardwood floors every 1-2 weeks, depending on foot traffic and how quickly the floor becomes dirty. For heavily soiled or damaged floors, or if you're unsure about the best cleaning method, it's best to consult a professional hardwood floor cleaning service.
