The clock movement is the arrangement of gears and wheels that runs a mechanical clock. Each part interacts with another, ultimately moving the hands, chimes and other features of the timepiece. The motion of the parts produces friction that requires adequate lubrication. Over time, even well-lubricated movements collect dirt and dust that interfere with the proper working of the clock movement. The movement must be cleaned using a specially prepared clock movement cleaning solution.
Place the 1-quart container in a well ventilated area. Pour the oleic acid into the container. If pure oleic acid is unavailable, Murphy’s Oil Soap may be used a substitute, as it is essentially the same substance, and works well as an ingredient in clock movement cleaning solution.
Add the acetone to the oleic acid. Slowly pour the ammonium hydroxide into the mixture of oleic acid and acetone. Do not pour too quickly, or the mixture will splatter. Ammonium hydroxide, 26 degree Baume, is a common, commercially available preparation of ammonia. The 26 degree Baume refers to the strength of the solution, and is equal to a solution that contains roughly 30 percent ammonia by weight.
Let the mixture stand for a few moments after adding the ammonium hydroxide. Clumps of soap-like material will begin to appear on the surface of the mixture. Lightly cover the opening of the 1-quart container. Do not seal it airtight. Leave the mixture in the container for about two hours, or until the clumps have completely settled out into the mixture.
Pour one gallon of water into the large container. Add the contents of the 1-quart container to the large container to form the clock movement cleaning solution.
