"Mistral" Ultrasonic clock cleaner review

Recommended Posts

As promised I would give review of this ultrasonic clock cleaner also can be used for cleaning carburettors.

Well it certainly cleans with remarkably good results. I cleaned a very dirty "Hermle" clock movement mixing this solution 7:1 in warm water. The parts come out of the cleaner spotless & shiny ,I rinsed with water and rinsed again with L&R rinse.
HOWEVER I was not aware that this solution has some sort of ammonia base and bearing in mind my workshop is a converted bedroom. The fumes were overpowering, windows opened doors shut & the wife was not happy to say the least. I will in the future have to use my garage when using this cleaner and perhaps apologise to the neighbours in advance. :mellow::mellow:

Conclusion: This cleaner gives excellent results and is very economical. However it must be used in a very well ventilated room. I recommend the wearing of a mask as well as the fumes are very strong indeed.  I will have to do some more research to find a good ultrasonic cleaner that I can use without the fumes.

Stardrops Floor-Cleaner....

Providing its just brass/steel, gilt, nickel etc, this works well, contains a small amount of ammonia and various ionic and non-ionic serfactants, with a little pine-oil.

Has sometimes the tendancy to 'blue' steel components or those coated with lacquer. Use in ultrasonic, a good squirt and at 50-80 degrees for 10 minutes.

Rinse well (4-5 times) then into Alc. and back in ultrasonic to de-water and dry.

Apologies for resurrecting an old topic.

I know Horolene is the de-facto cleaner - does this remove the tarnish as well?

I've been working on a Smiths Empire 151 that's had a run in with 3-in-1 or WWII tank engine oil and despite using my best efforts still seems to retains a slightly greasy patina. So are in the case of restoring an old clock, is the aim to remove this patina and reveal a clean bright surface, or just to remove the excess gunk and emulsified oil?

I have tried my "silkolene fuchs wash off" which is designed to shift motorcycle chain grease (which is designed not to be shifted) and even after 6 mins in the ultrasonic in that the plates don't feel clean!

Yes, horolene will remove tarnish, as will any amoniated cleaner. I usually buy mine at the clock and watch fair at the motorcycle museum to save the postage hassles, but Cousins will ship it.

I’m sure there are many cleaning fluids which will give a good looking outcome, but I work on the basis that Horolene is not that expensive and being as it’s designed for the job will do what is required and not leave any nasty residues behind or do any unseen damage.

    • people be honest.... Swatch is evil for the watchmakers and repairers, BUT not everything in watches from Switzerland is from the Swatch-Group. As far as i know, Selitta got sacked by Swatch as a Movement-Assembler for them and they started to produce Movements in their own Name with slight Modifications. As far as i know, they sell Parts to the Market for their Movements. In most cases, if a ETA-Movement fails, it is a valid Option to replace it with a Selitta Movement, which i consider the Solution for this Mess with the Swatch-Group...... I have no Connection to anybody at Selitta, but being a Swiss-Guy, i still like to have Swiss-Made Watches, but not from the Swatch-Group.   ok ? regards, Ernst
    • Just one more greedy act by Swatch. They started a number of years ago here in the US..cutting off supplies to watchmakers that could build complications that many Swatch houses couldn't even touch. Old school masters who had gone through some of the most prestigious houses in the world. Otto Frei has some statements on their page about it. I tell all my customers to avoid new Swiss watches like the plague,..unless they just want an older one in their collection that still has some parts out on the market, or they have really deep pockets and don't mind waiting months and paying through the nose to get it back. Plenty of others to choose from..IE Seiko,..or other non-swiss brands Even a number of Chinese brands are catching up with the Swiss,..and I think that in time, their actions will be their downfall
    • Yes. If that's not what you are experiencing...start looking for something rubbing. A 1st guess is that one of the hands is rubbing against the hole in the center of the dial. Especially if you now have lower amplitude in face up/ face down positions.
    • Once a movement has the dial and hands put back and it is recased, would you expect the assembled watch to have the same amplitude as when the movement is in a movement holder and is without hands and dial? Thanks
