We WD40'ed ASR33 ribbons at the Computer Mini lab @UMR till the material 
was white and we were printing with residual WD40 on the fabric.  On a 
rebuild of the machine in question, we drained off 1/2 pint of oil from 
the felt in the bottom, from both the ink operation, and just making it go.

Not sure why they didn't buy a new ribbon, but once it was rebuilt after 
4 years of use, it printed fantastic quality print with a new ribbon.

I don't know the formulas for ink but it was persuaded to continue 
printing with cloth / silk ribbons I've seen then and since.
