Scott,

Take all the modules out, including the RF deck if you can manage it (you 
will want a green gear unless you feel up to a gear train mechanical 
re-synchronization).

Remove the slug racks and all the transformers.  Put bits of tape over the 
IF can holes if you want to (blue painters masking tape works very well).

Then wash it. Wash everything.  Use 50/50  mix of household ammonia and 
409.  Paint brushes get the cleaner into small spaces.  Rinse well. Put the 
modules in the oven at 110 or as low as it goes for an hour, then leave 
them in over night with the heat off to dry.  Put some 100 watt lamps 
shining on the chassis at close distance if the weather is not sunny, dry 
and hot.

You may be amazed at how clean the thing is then.
