Our across the street neighbors had their kitchen remodeled. They went with black appliances, and even the hood over the oven and burners. The guys that installed it of course could not levitate it into place so they touched it. That left fingerprints. She was livid and had tried everything to remove the fingerprints. She came over to ask my wife if she had any ideas, and my wife asked me. I said car wax. So I got some of my paint cleaner-wax and off we went. Wax on wax off, fingerprints gone. She almost kissed me but realized her husband and my wife were standing there. She went right to the car parts store and bought some. He husband suggested once she finished with the appliances, she could do her car. That brought out a rather dirty look.
