Homemade Orange and Vinegar Cleaner

My wife's friend who came to visit a few weeks ago told us about a homemade cleaner recipe.  Take one or two orange worth of peels and put them in a 1 quart canning jar.  Fill the canning jar with vinegar.  Then let the jar sit for 3 weeks.

My wife tried it out last week.  It took a dark spot off the wall that a Mr. Clean Magic Eraser could not.   My wife also added some to a bucket of water and mopped the floor with it.  No sticky residue was left behind and the floor looked great.

Update 8/1
Over the past few months we have used the cleaner to clean windows (diluted in water about 1 cup to a gallon) with streak free results and mop the floor.
