    Default Ultrasonc cleaner concoctions.

    Hey gents!
    I just picked up a 15L ultrasonic cleaner off of evilbay and just wondered if any of you use one and what you se for cleaning fluid. From what little i've read most of the proper fluids are massively over priced and don't work any better than the homemade stuff. First job will be an alloy dirtbike head and carby. Was planning to try vinegar and dish soap.
    Any experience?

    We still have the Grease Monkey which I believe is now Blackstone Ney, originally used the grease monkey detergent which was by far the best product but hard to get over here.
    Years ago we started to use a Castrol product called wonderclean which was pretty good.
    Today we purchase from Unisonics Australia, they have a range of cleaning fluids.

    We found that the chemicals make or break the machine, the wrong chemical and your wasting your time

    You need to be careful, to acidic & it will damage the surfaces (mirco pits)

    What frequency is the cleaner, 40kHz is best for smaller surfaces (carbies, etc) 25kHz is perfect for blocks, heads etc.

    I would suggest, normal dishwashing liquid to start (approx. 75-150ml). the bubbles crated by the ultrasonics do the cleaning (they implode upon touching the surface), the additive helps soften the surface.

    if it has a heater, set it to 35degs. if not mixed some hot water in it. (cold water first, additive last)

    Let the unit degas the solution before putting in the part, approx 5 mins.

    Sorry Andy, didn't see this reply till now. I wound up liberating a few litres of solution from work. I have no idea what it was to be honest but the fitters in the workshop reckon it works a treat. And it did! I have done a bike cylinder and head so far. They came up a treat, the carbon fell out of the exhaust ports in big flakes. I have another carby here from a china bike that I want to give a clean up shortly. Might try the dishwashing detergent on that one. The other solution needs tossing, it was completely filthy after I did the head.
    It's a 40KHZ cleaner and has a heater. I had it cranked up to about 80. May have been a bit hot but it sure did the job. Bike is back together and I took it out for a canning today, ran perfect.

    Awesome, nice work mate. 40kHz produces smaller bubbles, which get closer to the parts before imploding.

    Becareful no to rest the parts on the bottom or it can reduce the transducer life (mounted on the bottom of the tank) if it doesn't have a basket/tray you can make a small s/steel one to sit on the corners of the tank.

    I have a small one at home, but worked on ones that are unto 3mtrs square, they work a treat & setup up right everything comes out brand new.

    Clean the wires jewellery, she will love how shiny & clean they come out.
