What watchmaking books do you have? If you have none, these are also tools you need to invest in, so texts like:
http://www.amazon.ca/Practical-Watch-Repairing-Donald-Carle/dp/1602393575
http://www.amazon.ca/Watch-Repairers-Manual-Henry-Fried/dp/1626549982
These are both older texts that will give you basics about how various mechanisms work, some simple steps on performing repairs, and yes sections on how to clean "the old fashioned way" without dropping $15k or more on a modern cleaning machine.
A good free text is TM 9-1575, which is a 1950's repair manual for ordnance maintenance, for wrist watches, pocket watches, stop watches, and clocks. Here is a link to download this document for free:
