The best way to clean your hardwood floors naturally is to not let them get very dirty in the first place. Frequently dust them with a broom or dust mop, and clean up any spills with water right away. When you do have to mop, you can use vinegar as a safe, all-natural alternative to other floor cleaning products.
Sweep or dust mop the floor frequently. This stops dirt from getting ground into the floor, necessitating a deeper cleaning.
Clean up spills immediately with a damp cloth.
Consider having a no-shoes policy in the house to keep the hardwood floors cleaner. Not only do shoes track in dirt, but they also grind it into the floor, necessitating more frequent mopping.
Mix white vinegar with water. Add about 1/2 cup of vinegar to every gallon of water you use.
Wet a mop or cloth in the mixture.
Wring the mop out so that it is just slightly damp.
Mop the floor, being sure to get the entire surface.
Wring the mop out, wet it, and wring it out again whenever it gets dirty.
Allow the floor to air dry.
