Irene did us a great photo article a little while back on how to clean a sewing machine (http://so-sew-easy.com/pamper-sewing-....
I've been neglecting mine recently, half on purpose actually, so I could give it a good clean out and take some video while I did it. Mine is simpler than hers, I can't access many areas so do check out the earlier tutorial for photos of options that might apply to your machine.
She suffers from the same problem that I do - rust and corrosion from damp or humid conditions. Hopefully your machine won't look as bad as ours, but if you live in a very damp, rainy, humid or salty area, you may need to take care of it a little more often and be prepared to add a little more oil.
