    One for general parts like cases and bracelets.

    Another for movement parts.

    Finally, any decent recipes for general jewelry such as gold rings, earrings, chains etc.

    rix,

    Most home-made cleaning solutions use a water base. That you have not had answers regarding a water based solution for cleaning watch movements doesn't surprise me! I use household cleaners and water in an ultrasonic for cases and bracelets. But when I comes to water based solutions for cleaning either watch or clock movements, I don't use them! Others may recommend water based solutions for cleaning clock movements. But for watch movements? I doubt it. And if anyone does, proceed cautiously!

    For cleaning wrist-watch parts I am currently using something called -- "petroleum distillate N.O.S. UN 1268" -- which seems to clean and de-grease fine, (comments anyone ?)-- otherwise known in UK as "lighter fluid".

    I tried an alcohol based fluid but got rusty parts presumbly due to a small water content.

    When you use lighter fluid in cleaning watches, you are playing with fire, or at least a strong possibility of fire. Lighter fluid is has a very low flash point. It is designed this way so that it will ignite from a small spark in the lighter.

    Commerical watch cleaning solutions are based on about 75% Stoddard solvent (paint thinner) and 25% VM&P Naphta. These have a higher flash point and are more difficult to ignite. They are still a fire danger, but not so nearly so as light fluid. You need good quality materials that will not leave impurities behind when they evaporate. Commercial cleaners also containe non-ionic detergents for oils and greases and other materials to dissolve metal oxides to brighten the metal. You cannot make these cleaners in small quantities for even twice the price. I do make my own rinse using the Stoddard solvent and Naptha, but it took me a while to find good brands, but I buy commercial cleaner.
