you beat me to it...as I was going to suggest after seeing this far, that tub needs to come out and get scrubbed....
not to mention the splash shield, and other hidden areas.....I have a feeling your going to find a lot more.....
but once done, you know it will be thoroughly cleaned....
you almost want to take it apart, take pics, reassemble it, and test out some of these washer cleaners, to see if they actually work.....that would definitely be a machine to test them out on...
keep us posted
