Most floors can be safely and effectively cleaned with a solution of water and liquid castile soap, at a 1:40 ratio (one part soap to forty parts water). A few drops of essential oil can be added, especially if the liquid soap is unscented.

A mixture of white vinegar and water, at a 1:1 ratio (one part vinegar to one part water) will also work. Mixing up the vinegar and essential oil twenty-four hours in advance will make the scent stronger and longer-lasting.

Wood floors should be cleaned more gently, with a solution of white vinegar and warm water at a 1:4 ratio (1 part vinegar, 4 parts water). Dampen a cotton cloth and use it to mop the wooden floor.
