My friend Liz and I share a penchant for eco-friendly cleaning products and an aversion to greasy fingerprints and streaky windows.  She swears by the Mystic Maid Original Microfiber Cleaning Cloth, using them with plain water to clean up after her three boys… I mean, her two boys and husband. Either way, it’s six grubby hands.  Because these microfiber cloths are easily wrung out, they’re particularly good for cleaning stainless steel, glass and mirrors, leaving them clean and streak free.  And while they’re expensive ($14 including shipping when ordered from Mystic Maid), they quickly pay for themselves in what you save on cleaning sprays.  Just toss them in the washer to clean; they’ll last for years.  (Oh, and Liz told me to remind you to never use fabric softener when you wash them.)
