I have an early 1900 Regulator school clock. It runs 7 days on a winding, but after several years it starts to quit after 6 days then 5 days etc.
I use John Deere Multi Purpose Lubricant. It has restored the clock 2 times over the last 25 years.
I tried it on a clock out of an old Plymouth car and discovered it could cause a new problem. That clock wouldn't run until I used the JD product. However it would gain 1/2 hour a day. There was a lever on the back to adjust faster or slower and putting the lever all the way to slower had little affect.
The John Deere Multi Purpose Lubricant isn't anything like WD40 as it doesn't evaporate and it leaves a protective coating.
