<human>:  How do I clean my hardwood floors without using harsh chemicals?
<bot>: To clean hardwood floors without using harsh chemicals, you could try using a solution of water and a mild detergent, a broom and a mop. Vacuum or sweep the floor to remove any dirt or dust, and mop the floor with a solution of water and a mild detergent. Rinse the mop between each pass, or use multiple buckets and mop heads. To remove stubborn stains, mix 1 teaspoon of white vinegar with a quart of warm water, and mop the stain. Use a microfiber cloth to dry the floor and buff it if needed.
