I just purchased microfibre cloths for dusting, doing dishes, drying our dogs and washing my floors.   I use them for everything.  They are chemical free, I no longer buy paper towels so it saves the landfill, they reduce the use of chemicals (no more dusting sprays), they last forever and they are amazing cleaning tools.  For my birthday I got a Swiffer Sweeper and since I won't buy the throw away chemical laced pads I just use my microfibre towels and attach them to the Swiffer instead.  When I clean windows I just dampen one of the cloths and the smudges come right off.
