Mellotronists

When attempting to make pinch rollers nice n' silky smoot, what's the 
preferred method of cleaning and then lubing of those little rollies?
thanks,

btw - if you've thought about replacing your motor card, get a 
Streetly one.  I recently installed one and it's a whole new 
experience: no whine, perfect.  The installation is easy, even if 
you're the worst solder monkey like me.  Perfect complement to that 
new tapeset.  Thanks MS & JB!
