Ultrasonic Cleaner

Look in all the nooks and crannies - my daughter picked me one up at Hereford Aldi today, but she said she had great difficulty finding them, as they were tucked away on the bottom of a shelf behind a pile of unrelated stuff.

Melfresh is what we used to use on the camping cups, I think you can still buy it.

Not if you're more than a certain distance from the branch. It'll just tell you that there isn't a nearby branch and won't let on where the nearest one is.

Try just your town, or a nearby town.

Many thanks Mike, I can drop in on the Camberly one as I go to Camberly frequently.

Doesn't work.

Portree, nope. Fort William, nope. Inverness, nope.

There is NO way on the Website to display all the stores in your area (e.g. Scotland) and let YOU pick the closest or most convenient.

Perhaps they don't have stores in foreign countries ?

Sorry I'll get me coat.

They seem to be available on Ebay at twice the price plus postage - search on "ultrasonic cleaner":

Brian,

So IV= Inverness postal area and 51 is the Isle of Skye!!!!!!

Your nearest one stated is FORFAR or one in the Glagow group.

I put in my wee hoose in PH22 and it came up as Forfar.

And I plugged in Aberdeen and Inverness as well. However, I put in Perth and got ALL the Scottish branches. Alexandria is your(joke) nearest.

Apart from seeking Andie Stewart or Para Handy( Oh, Yes), the only way is to get one of us to mail items from a local branch further South.

Kindest regards from the other side of the Wall

Norman

Hi Tony, That seems to be a special made big enough to take a CD. I just tried a CD in mine & it won't fit.

I visited the Catford branch yesterday (Monday) morning, and they also had none. No idea whether they had sold out or never had any; just thought it might save someone else a trip.

Got mine today, had a bit of a play with it. Seems to work quite well - I bunged in a few gunked up mouthpieces and some cruddy silverplated keywork. Whilst it didn't quite 'put a shine' on the items, it certainly did a good job of cleaning the crud off. What I'd really like is one with a 'bath' that's about 14" x 2" x 2" ( about the length of a flute body ) - and if I assume that this gadget works for a given volume, it might be possible to hack it apart and adapt it to fit a bath that's more useful for my purposes.

Regards,

Mine works OK but "buzzes" whilst operating. GIven it claims to operate at

42KHz why the audible buzz?

Plenty of info on Google about that. I did some searching before buying mine and found a good article that went into the details. The lower the frequency the more power the bubbles have as they burst (you'd think the other way round but no) but the more audible noise you get. The author felt that about

40kHz was optimum although as high as 70kHz is used by some makers. Going by that the Aldi one seems well designed.

See my post some days ago... The power oscillator works directly from rectified mains with no smoothing applied to the voltage that it works from. This means that the oscillator is going to be starting up and shutting down

100 times a second. Hence the buzzing, Be fun to put a 150uF capacitor in and see if it runs smoother, is more powerful or just burns out...

I had a word with my MD yesterday about these cheapo units, apparentl

our company was buying these in from the far east for $5 each, yes $ !! all badged up with our own logo and in bespoke packaging, we sol them through various retailers at a nice profit, but over a period of few months, every single one of the batch was eventually returned a faulty. We do not have anything to do with them any more, as we desig and manufacture our own high quality range. The trick with the Aldi type is to make sure you do not leave it turne on for very long at a time, they do not cope with the internal hea build up very well.

The heat sinks are there, there's just nowhere to dump the heat to. Modifying the cases to have holes and a fan or a liquid thermo-siphon to the tank should make a significant difference....Not economic for resale, but we aren't buying them for resale:-)

I bought a similar item off eBay a year of so ago. One day it got a lot quieter. I pulled it apart and the transducer had dropped off the tank bottom. It was epoxied on, so I guess I should have stuck to cold water in the stainless steel tank. No mention of this in the instructions! Now that doesn't sound to hard to fix, but my model had on/off buttons built into the lid and no special strain relief for the wires leading to them as they passed through the hinge, so these were subject to so much bending force that they'd become intermittent some months before. And the way the thing had been put together was really awkward and a brain ache. It's like the electronics are good, but the product they're built into isn't. I guess I'll get around to repairing mine when really need it again.

Yes, the buzz is unfiltered rectified mains. The 40Hz is modulated on this. There's some audible screeching too, through some non-linear process reducing some of the 40khz down into the audio range. Apart from the fact that it sounds horrible, I'm a bit suspicious that one day they'll find that extremely 'loud' but inaudible ultrasonics are bad for your ears, so I prefer to run it in a different room to the one I'm working in.
