Wash your hardwood or pre-ﬁnished ﬂoors the old-fashioned way. Add a 1/2 cup vinegar to 1 gallon of hot water and mop or scrub as usual (make sure to barely wet your mop or cloth). Dry the ﬂoor completely with a towel afterward -- standing water is the enemy! Don’t try this technique on waxed ﬂoors because it will strip off the wax ﬁnish. To lessen the smell of vinegar, add a drop or two of essential oil to your mix. Lemon- or lavender-scented oils are excellent options.
