Cleaning dirty floors requires the right products and approach. Gather the necessary supplies based on your floor type like hardwood, tile or carpet. This includes a broom, vacuum, mop, bucket, cleaning solution and cloths. First, sweep or vacuum the floor to remove loose dirt and debris, paying attention to corners. Then, use the appropriate cleaning solution for your flooring. For hardwood floors, use hardwood floor cleaner. For tile or linoleum, mix a mild detergent with warm water. Always follow the manufacturer's recommendations to properly clean and maintain your floors. Hiring a professional cleaning service can also help achieve clean, sparkling floors.
