Let me see if I understand this... Your father's day present was to
allow you to roam the flea markets in Tallahassee, instead of spending
time with your daughter?  :-) :-) :-)

Outside, no problem.  Cotton swab or Q-tip and glass cleaner will 
do it.  Inside, a bit trickier.  Unscrew two side screws.  Then try
and reach with a Q-tip.  It is better if you take the focusing
assembly apart (tricky).  Then you can clean carefully, tighten 
interocular and focusing, and slightly lubricate when putting back.

For the outside case I recommend cleaning/polishing.  I also
recommend cleaning the electrical contacts (especially the switch)
and installing a frosted halogen bulb.

I am working on a book on the red button viewer which hopefully will
be ready for the NSA convention.  This is a second edition.  First
one was in 1994.  Also, I recondition, repair, enhance (this includes
a 8p conversion) red button viewers.

PS.  You did not tell us how much your "present" cost... maybe trying
     to avoid making us jealous of your good fortune? :-)
