Many hands make light work.  Window washing can be fun!  First, let the kids make a mess. Crayola makes Washable Window Markers.  Let your little Picasso sketch the dog, or encourage the twins to engage in a rousing game of Tic Tac Toe.  Easy, green cleanup – spray with lemon juice mixed with water, wipe with a damp towel, and then wipe with a dry towel. Sparkly windows, happy kids.
