Ultrasonic Cleaner

At that price, its a pity that you can't synchronise multiple oscillators. It'd be worth buying a dozen just to use as parts to make a larger cleaner!

Mark Rand RTFM

Would you need to synchronise them for your idea to work?

I must admit, it looks like a very good deal. While this isn't the type of thing you use often, at £15 it is probably worth the money.

If I was to buy one of these what sort of things can be cleaned in one, am I on the right lines with carburettor bodies and brass fittings etc. Having never seen one before they sound good in the advert, but what does everyone who has one use it for and how good is it?

Thanks - Paul.

In the past I've used one to clean clocks and pocket watches that were very scruffy- always to good effect.

I've also used one for car parts (in the days I ran old cars).

Good for jewellery, except pearls!

At £15, a just in case purchase seems justified.

Hmmm, same here...could be quite handy.

Thanks for the heads up.

Regards,

I have _heared_ that those El Cheapos have only some kind of buzzer, but no ultrasonic transducer. So the result might be not what you wanted.

Just my 0.02 EUR

We used to have one at work that was used almost exclusively for false teeth!

I'll get one for me mum and do the carburettor bits while she's away on holiday!

Ultrasonic baths are very good for cleaning parts with awkward holes and internal passages (carburettors). A lot depends on the fluid used, I use an amonia based solution for brass clock and musical box parts and it brightens them up very nicely, however it tends to turn aluminium alloys a bit black so not very good on carbs, I would probably use white spirit for doing them. Most users of these little units use a soapy water type fluid, it just needs something in there to break the surface tension. they are great for jewellery and spectacle cleaning. I design ultrasonic cleaning machines for a living, our latest machine has just been dismantled for air freighting out to China, it is 13 metres long and is going into a factory making computer hard drives. Unfortunately £14.99 will not buy one of these, you will have to save up around 1.1 million $US

So, can you tell us if a large machine with multiple transducers to excite the bath, needs to have those transducers sychronised in some way?

(The question sort of came up earlier.)

They are normally wired in series, be they piezo-electric or wound components, that way they all get the same drive.

I use one for cleaning SCUBA breathing regulators. Brings them up a treat when used with the 'secret solution' .Amazing how much crud, corrosion and salt water debris it brings off! I made one years ago out of one of those things that they use in photocopier rooms for shaking the paper...well I think that was what it was for!!! At £ 15 I'm having 2 of them!!

I would be surprised if this cleaner is actually ultrasonic, though I would be glad to be corrected by anyone who has bought one. Similar equipment at this price in the past has only been described as a sonic cleaner and has merely comprised a motorised shaker operating at an infinitesimal frequency compared to a unit with a transducer. I threw mine away when I got a real ultrasonic bath and saw the difference in performance.

Hi Cliff,

When you say that you got a real ultrasonic bath, where did you get it from & how much?

Cheers,

Zed

Hello Zed.

I got mine several years ago from one of the clock material supply houses, I forget which one. It cost about £300 as far as I recall. If you are looking for such a tank I have heard good reports about Walker Electronics Ltd.

Cliff.

Surely if advertised as Ultrasonic and found not to be so, there would be grounds for a Court case?? Goods not as described and Goods not fit for purpose etc etc IMHO!

I'll risk it for £15...any one else?

This one is clearly described as ultrasonic, it also bears a close resemblance to a small ultrasonic cleaner wholesaled quite widely for about the same price.

I just wonder if anyone is going to be able to buy one before they run out of stock. Down to my local Aldi at 9am on Thursday I think.

Yep - I don't expect it will be long before Aldi stock's gone...
