    Default Ultra sonic cleaners??

    Been poking around on eBay and found these:

    Just wondered if anyone has had any experience with these or similar and if so what are the pros and cons.
    Naturally, I'm looking at them as a means to clean injectors mainly, as well as other small bits and pieces particularly electronic bits.

    If it ain't broke, use a 12" shifter.....that usually does the trick!!

    My father used to work in cartographic draughting. They used a small U/S cleaner - about the size of a coffee grinder - to fix the ink pen tips which clogged up dependably. I guess this is a similar situation (tiny orifice) to the injectors.

    Occasionally, he brought it home to clean my mother's jewellery. Worked there, too. Maybe this aspect would get you brownie points?

    Regards, Adam.

    The one we have at work does a good job, but we have had to take it back to Jaycar a few times, last time they replaced it and the new replacement unit is showing the same simptoms...
    Perhaps I justy got 2 lemons but when they are working they are brilliant. Ive cleaned Tx valves and all sorts of small things to a very good degree then finish of in a flash solvent(if it can be). It leave spark plugs brilliant too. - Chris

    Alan, I have one (just a commercial unit not an industrial unit), and it does indeed help loosen everything up, the jewellery gets done every couple of months, but I find it works better if I soak everything in jewellery cleaner first, the combo of the two works well. Also used for pen ends, glasses, shaver blades/heads and metal watch bands.

    It's not a miracle cleaner though, and the results are far from the industrial units I've seen. Heavy stuff won't move although with a bit of brushing added in it's better then scrubbing away.

    I paid around $60 which was OK for the occasional use.

    the best way of cleaning injectors. sit the injector tips in ... couple of hours they ar a little bit cleaner. all day and the paint is gone and the injectors are clean i thought these machines where $100. for those prices you could start you own Af members injector cleaning. injector places charge something like $3o an injector. all you need is a flow tester and your set

    Yeah i got a commercial one from Jaycar too...
    works great on jewelry but dunno how it'd go on much else.

    Speaking with a guy in Melb, the mechanical injectors dont really like to be ultrasonic cleaned, at $90 ea its just better to buy new ones.

    If you do that, I'll pay the postage on the old ones if ya send 'em my way
    I always thought that Ultra sonic has always been the accepted way of thoroughly cleaning them but if someone can tell us why it isn't I'm sure we would be interested.

    Alan,
    Ultrasonic cleaners are used in Dental laboratories all the time. One of the best solvents to use is just kero, we used to use it to remove wax based polish paste form chrome cobalt and gold castings after finishing and polishing. Hot water in small tank with detergent is also great. Kero is probably the most volitlile substance I'd risk using.
    I have seen some cheap ones flogged by door to door reps and they aren't worth the scrap they are made of most of the time.
    It'd be a risk buying one over ebay. If you wanted one for injectors, that isn't it. I have used one similar, just a different colour scheme, and it wouldn't clean a dirty spoon.
    If you want a good one go to a specialist or try one of the Dental supply companies.

    Yep, if they don't clean up and spray properly with a soak in white spirits and a blowout with the air hose there is little that can be done to them. The newer replacements (brass body) seem to make the car run better, they are a significant improvement over the old steel body version.

    Aren't the Jaycar units designed to use non-flammable cleaners only??

    This topic came up before and I mentioned my experience with them while working for a safety equipment company. I don't know whether you would call the ones I used industrial (approximately 3 litre capacity) but they were larger than the ones on e-bay. Regardless, as long as you follow the correct sequence with readily available chemicals it is a very effective method of cleaning small orifices, such as in carb parts, injectors and even breathing apparatuses. Check out my thread, it lists how to go about it there.
