I have seen much worse. Usually my 7 year old DGD cleans them out with an eyelash brush. You can get packages of them from a beauty supply place - they get into the tiny little places you need to get the fuzz out. She loves to do it so I let her. My almost 4 year old DGS loves to oil. Actually he loves to baptize things. He has learned that Tri-Flow works better than SM oil. Anyway I help him use the oil very sparingly on each point that moves. The oil build up it may come off with rubbing alcohol but you don't need to worry about that - once it is oiled and moving the stuff on the surface won't affect the machine. Rubbing alcohol will take off some finish -be careful. Muv has a wonderful tutorial on the sticky. Use her methods on that machine. It isn't nearly as bad as you think. I wish they all came across my bench in that kind of shape. You are right - when you see a machine that is looking pretty pristine - it hasn't been used much and probably for a reason. Take your time and you will have a very nice machine. Some of the more extreme methods of cleaning up are not for that machine. Maybe for some old beater or one that is a real mess.
