Mop hardwood floors with 1 gal. hot water. 1/2 cup vinegar, 2 Tablespoons baking soda, and a few drops of dish soap. Shiny floors, house smells grand. I also mopped my dingy linoleum tile floors in my kitchen this was better than any floor cleaner I have ever bought off the shelf!
Heavy Duty Floor Cleaner for Ceramic Tile: 1 c. white vinegar, 1 T. liquid dish soap (Dawn), 1 c. washing soda (in laundry aisle), 2 gal. very warm tap water. It leaves everything smelling amazing. Do not use on wood/waxed floors, it will feel gunky.
