If you have little kids, Mr. Clean Magic Eraser really is magic.  A friend told me about it when we were in the process of moving and it worked wonders on scuff marks on walls and stairs, fingerprints everywhere and dings in the walls.  It also does an amazing job on cleaning lawn furniture to make it look brand new.  I gave one to a friend and she was giddily wiping down walls all over her house saying - "Wow, now I don't have to repaint!"  Check them out - they really are a timesaver.
