Are they worth having?

I'm speaking of ones like:
http://planet.farnell.com/email/cpc/WebOffers/ultclenr.htm

The fact that it loks like a toilet is obviously a bonus. It would be
almost worth it to have dentures just to be able to put them in a
cleaner that looks like a toilet.

Can ultrasonic cleaning damage things? I can see that dunking Grandpa's
1959 Omega Constellation in there is probably not the right way to go.

I've used them in the labs I used to work in, and those (300quid at the
time) work magnificently.
Mainly used at work to assist the dissolution of things that were reluctant
to dissolve.
But took in loads of car bits etc for cleaning. Greatly assisted by getting
the right solvent for the thing you are cleaning.

Perhaps the £17.99 one I mentioned won't be quite so magnificent.

Couldn't say. Perhaps it is the case that volume production for a domestic
market coupled with improved production efficiencies have made them cheaper.
Certainly the ones I used will have had higher quality casings but the
untrasonic element may very well be just as effective. Alternatively it may
be about as much use as wrapping tissue around a comb and blowing at it.
Not helping much am I?

A good test for the effectiveness of the ultrasound is to dangle a bit of
aluminium foil in the liquid, then see how perforated it gets.

Not really Daniele

I have a larger tank type with heater and drop in baskets. For them
to be effective, the water generally needs to be quite warm to hot and
obviously the container large enough for requirements.

We've got one similar to that - I think Aldi were selling them for £15
at the time. Great for jewelery, glasses and small stuff. I've used it
to clean up bits of dive equipment (regulators, etc.)

No-where near as powerful as "lab quality" ones but for the price...

Certain gemstones are not recommended for them afaik (tanzanite etc)

Perhaps that's the reason for yesterday's disappointing discovery that
Kryptonite may be a boring white rather than the green that we know it
to be....

Yes, they're great and now they're under 20 quid.

A cheap one now works as well as an expensive one used to (for practical
sizes). The limit now is in their working lifetime. because the new
cheap transducers do have a finite lifetime.

I bought one very similar to that from Maplin. I normally use it for my
hobby of electronics, to clean circuit boards. However, my wife dropped
her digital camera into a dirty stream last year and it was complaining
about flat batteries and the view finder was clouded somewhat.


I took off the back face of the camera and dropped it into the
ultrasonic bath for a few sessions of cleaning. Rotating it after each
session. I used tap water and a drop or two of Fairy washing up liquid.
I asked on here about doing this, as the camera was either a total loss,
or it could be recovered. After a good dry out, I am pleased to say that
everything looks fine and that it is back in everyday use again.

Yes, quite good actually. I've got a commercial Sonicor one and a
similar one to the CPC one. The smaller one isn't as quick but the
performance is good and there certainly isn't a twentyfold difference
in performance even if there was in price. The price of the
commercial units is a function of low volume and a price insensitive
market rather than performance and build quality.

Beware of cleaning jewellery though - they can loosen the mounting of
some stones.
