Ultrasonic Cleaner

From the investigative surgery that has been undertaken, I would suspect that the buzzing is caused by the fact that the Oscillator runs from unfiltered rectified mains. It's going to be starting up 100 times a second.

A further conclusion is that the instructions calling for a 3 minute rest between each 3 minute operation period is because there is no ventilation to take the heat away from the nice heatsinks that the transistors are bolted to.

If left plugged in, but not locally switched on to clean, it still keeps warm - so I suggest this device is unplugged (or otherwise remotely switched off) after use, rather than leaving it in 'standby'.

... and by the time I'd tested it an hour later this poxy teranews server had gone down yet again as it does every two days or so. I'm beginning to think they turn it off regularly to try and get the light use customers to pay for one of the more comprehensive packages which they host on other servers.

Anyway, as everyone else has already said it appears to be the dog's danglies. Proper 40kHz ultrasound and it really does shift that dirt. Shame the container isn't just a bit bigger but for £15 it seems churlish to complain. Things I've tried it on.

Spectacles - yuck, must do that more often from now on. Did I really wear those?

My toothbrush.

Electric shaver head - not very good when the dirt is mainly loosely attached particles but I guess the grease and grime underneath got zapped

Hairbush and comb - chemically clean and degreased without boiling water - neat :)

A thoroughly manked up Bosch electronic fuel injector out of a Sierra Cosworth - took several cycles and could stand a couple more but even hard baked on carbon succumbed in the end. Very impressive.

The cap off the washing up liquid. Nowadays these seem to block up regularly with a sort of glue like jelly which won't dissolve very well even in boiling water. I'm forever trying to poke the stuff out. One cycle and it was completely gone.

Clearly you haven't done the 'mean old men' course! The washing up liquid is far to concentrated. Dilute with 1 to 2 parts water and the nozzle doesn't block. More money to spend on 'toys' such as ultrasonic cleaners too!

I'll be rounding up some old sparkplugs tomorrow...

Certainly does a good job on the specs, but I have to report that the unit totally failed to clean my workshop tea-mug. It does fairly well on the outside, especially where the (remaining half of the) handle joins the cylindrical bit. Hardly touches the grot on the inside, so it's back to soaking overnight in a bowl of bleach once every blue moon, or so.

I just got someone to pick me one up in the Portsmouth branch.

If it's anything like my workshop mug it'll need a hammer and chisel to clean the crud out.

Stephen et al, Might I suggest that you try:-

This should give all the supermarkets- and their 'specials' come up on a weekly basis.

If you give the Aldi entry your post code, it will give your nearest branch. Hope this helps.

Stainless steel scouring pads from Tescos shift workshop mug grime in seconds.

Try a "Sterident" tablet. Not sure where I learned this (I don't have false teeth) but I used it once on an old mug 1918 "Victory Mug" that was in need of restoring.

I find a bit of wet & dry works wonders (about 800 grit -finer if it's not so dirty!)

Got to my local Aldi today, but they didn't have any (no sign they ever had any actually). There seem to be quite a few on ebay at the moment though!!

They did have some interesting grinding wheels, about 8" diameter by

Regards Kevin

I bet the £8.99 Aldi angle grinder would fix it in no time flat.

Next cuppa might taste of kipper pate though ;-)

Don't know where you are, but there were at least two left at Buxton Aldi this evening (saturday).

Doesn't that go off with Coke? Also, do _I_ have to tell that a Brit?

Did mine, with a teaspoonful of sodium bicarbonate inside, then filled with hot water, placed in bath, also filled with water.

My rusty, greasy and filthy collection of 'you name it' nuts and bolts came up a treat in a bath of 'Muc-Off'. 'Wonderwheels' might have done even better...

They've now been sprayed with Scottoil:

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.
