Hi All, I recently bought a 1890's school house regulator and the movement is pretty gross. I am not wanting to attempt to take the whole movement apart as I am a newbie to clocks. I read a few threads about dips... I wanted to be sure I have this correct before I screw something up. Since the clock movement is pretty grimy, I bought some Naphtha from Lowes. From what I understand I can use this (outside, with gloves etc)... To soak the brass mechanism and it should eat up all the funky greasy, grimy bits. After that, I should rinse the movement in hot water. Then a quick soak in Denatured alcohol should remove any water from the movement. Lastly, I will need to reoil the pivots etc... Couple questions: 1. Am I missing any steps? 2. Do I need to take a toothbrush to the movement while soaking in the Naphtha? Or will it do its thing all on it's own? 3. How long can I soak the brass movement in the Naphtha? 4. How long in the denatured alcohol? 5. Mainspring re-oiling.... This bit I have no clue as how or what to do.... can someone help me out with this? Thanks guys!
