I cleaned up this cuckoo clock a few years ago and used electrolysis to clean the steel parts.

Movement, Regula 01, marked Made in Germnay, US Zone.
From the back, LH has winding ratchet with square-cut teeth, RH has coiled spring.
Count wheel outside the plates, pin wheel between them. Strike lifting piece outside the front plate.
No centre shaft, the hands are mounted on a stud fixed to the front plate.
It takes more than a six foot chain to run for a day, two metres would be enough.
From the front, LH chain 63 links/ft, correct, RH 58 links/ft, winds roughly.
Overall case height 16".
DRGM on the locking/warning lever.

The MB mentions various sites giving details regarding the use of electrolysis for rust removal but the 'tiscali' one no longer exists. This one does www.qsl.net/2e0waw/rust.htm.

There was rust on all the steel parts and general debris everywhere. The case was sticky with residues of tobacco smoke. The bellows had a few remnants of leather.

Here are some before and after photos.

I already had a bench power supply with a constant current facility so it was easy to perform the cleaning.

We've had some discussions in this forum on how to do it. Use search if curious.

Hint: Search on "electrolyte". You'll get more hits.

Thanks to you all. Obviously I wasn't being entirely clear. I've used electrolysis for cleaning quite often and was just posting an example of how effective it is, together with the URL of a site which gives details of how to do it.
