Had cleaned most of the machine (a WU 100 Series) and while working on the keyboard I realized I did not take a "Before" photo of the greasy mess going on with this machine....

But this halfway of the keyboard being cleaned, which was all I had left to do on the machine will give you an Idea of how nasty it was.....

A box of Q-Tips and pint of acetone later....

Don't know what grease WU used on this but it left a waxy sticky brownish/black gooey haze on everything (probably some nicotine residue from a zillion ciggies too!)
I started out with alcohol but it just wasn't cutting it then switched to Acetone as there was not any plastic on this machine to worry about and took that layer of crud off like magic.
