Thanks rogert63 for your very quick reply. The background reading I have done so far mentions things like, avoid the ones that look like a toilet and its only any good if it will perforate a foil dish/tin foil and yet others have achieved very good results from the budget machines - if anyone else could share their experiences of brands or retailers  - I'd really appreciate it - my wallet isn't ready for Bergeon just yet.

the cheapest ultrasonic on Aliexpress (around $22) 5 months ago

@PJA are you using the ultrasonic cleaner to clean watch parts? I'm keen to get one as well and would like to hear how you find it. Did you get the little baskets like this https://www.esslinger.com/brass-ultrasonic-cleaning-basket-with-stainless-steel-mesh-1-diameter/

for the watch parts? what cleaning fluid do you use and do you need to rinse or anything ?

for the small parts, such as hands, crowns, screws etc. I use this basket (I've gotten one at the local Dollar Store), which I removed the chain off, and it works really well. My basket is a bit bigger than the hight of the machine and I kind of squeeze it with the cover which is no problem at all. As for the bigger parts, I just put them on the bottom and let the machine do its works. I do not have any experience with any professional machine nor really have a need for at this time (something that same me money and space). the machine comes with two power 30w and 50w and I use the 50w for the longest time possible (30 minutes) and sometimes for watches that I tend to buy at the flea market or get from friends, I double the time and give it two rounds.

Do not waste your money with Esslinger unless for items that you can't find any other place.

I had that same and it blew (likely transducer failure) after one year of not so frequent use. So I recommend that you go easy on it.

So far so good for me. As I said, I don't use it much really, so for the once in a while use, it works fine, even if I'll have to buy another one after a year or two, I may buy a bit better but it still cheaper than putting a few hundreds of dollars on a professional machine, unless I'll have to use it once a day or so.

Agree. I didn't had the time and will to locate a spare transducer or better diagnose the fault. Now I'm back to shaking a cup, to be honest it seems to produce the very same results.

One note on those blue demagnetizers, dont just set the movement on them and push the button, that will actually magnetize your part. Hold the object above the unit, press the button and slowly draw it away with a slight twisting motion, repeat a few times and you should be good to go.

At some point I'd like to add an untradonic cleaning machine to my workshop.  I work on clocks and watches so I'd probably aim for a larger machine.  There are lots of eBay sellers selling machines like this:

https://www.ebay.co.uk/itm/302691315924

They are so cheap I'd almost consider a small one for watch components and a bugger one for clock parts.  Question is, are they any good or am I better going for a more expensive machine?

Thanks

Antique clocks should never be cleaned in an ultrasonic. They should be cleaned by hand.  

 

I use both methods. I peg the pivot holes and the leaves of the wheels and generally clean by hand. Then but the parts through the ultrasonic and then hand clean again to ensure every part is spotless.

I have a cheap Chinese one, different brand, but similar to that.

I've had it for about a year nad its still working fine, but it only sees occasional use, not every day use.

Some very early clocks such as Lantern Longcase and Bracket where the brass is cast have impurities. These are best kept away from modern cleaning and the solutions.

What oldhippy said regarding older clocks. Work-hardened brass is full of microscopic fractures which become knackered of you use ultrasonic. 

The stainless Chinese cleaners are good. Just don’t run the ultrasonic for more than 5 minutes at a time (you shouldn’t need to anyway).

I just got one and it seems to be doing a good job so far, and was a cheap-ish Chinese one.

Sorry to derail the topic, but in reference to the quoted post, might this be a good point to ask rodabod - what adverse effects might running for longer than 5 mins have?

Well, I managed to burn mine out by running it for too long. I'd heard it could be a problem before. It's the ultrasonic element which is the problem, not the heater. I've been running for years ok now while running it at five minutes at a time. I usually run it at around 50c.

Same here. But in fairness it's not a priority for me to get another one.

Thanks for all the replies.  Some good advice about cleaning antique brass here which I'm well aware about and the use of amonioniated cleaning solutions.  Conservation is always a hot topic but for 20th century brass made of rolled brass the brutal cleaning methods are fine.

Back to the ultrasonic cleaners it feels like these Chinese units are good for occasional use and only for short periods of time which probably suits my initial use anyway.

 

If you happen to burn out the ultrasonic element can you get a replacement or is the unit a throwaway item which parts are not available.

 

My other option is to purchase a higher quality unit.  Can anyone suggest a fairly priced unit?  Elma is an option I can see but they do cost 7 times the price of the Chinese unit!

Well there's 'buy cheap buy twice' and then there's the buy at your level mentality. If you have started employed by a company and then move on to self employed then hands down you'd buy the most professional equipment necessary. It's all up to you at the end of the day. In experience of equipment such as this it won't be worth repairing a cheap unit. Read reviews of the products, if enough people say it burnt iut after a few weeks - which often on ebay and amazon, they say exactly that - then steer well clear.

I couldn't find a replacement U/S transducer, so I had to throw it away before moving. A typical consumerist waste.
But using the right products any mov.t can be perfectly cleaned without any machine and the saved money be spent on more important tools.
