Ideas for sealing a cheap noodle machine?

Since I used buttered bread dough on this, I now need to open it up and clean it out good instead of a light wiping. So, checking to see if anyone might have any ideas of sealing the rollers as they do a good job of messing the dough up (discoloration and ripping and tearing the edges. Though, I think I did get rid of the discoloration the last time I used it).
