  • [Gloat!] Ultra Sonic Cleaner!

    http://www.amazon.com/La-Sonic-Conno.../dp/B002HIHZYW

    Just like this one.

    Got it a thrift store for $5. Came with brand new "cleaning cloth" and "brush" still sealed in plastic. No sign of the cleaning solution.


    Took it home powered it up it seems to work.

    We have one at work... A huge multi-station one that looks like a deep-fryer. We use deionized/ultrapure water in one set of tanks and "cleaning solution" in the other.

    At home I mostly work brass and aluminum and some titanium on my lathe as well as a range of plastics.

    I am thinking this will do good to clean small parts... but I am uncertain as to what I should use as "cleaning solution" for degreasing/oil-removal.

    if there aren't any knucks or cranies in the parts to be cleaned ..then they don't need an ultrasonic tank ..
    I hear that you can suspend a sealed bag in the water with your components in it ..the bag then can contain most cleaning solutions.

    similar one to that are available in the UK from aldi...think about £17

      Great idea with the bags. I have some tiny zip-seal bags that might work.

      Typically if I make something at home I bring it to work and run it through the tank at the end of the day. Current owner is very permissive of "government projects" so long as they don't disrupt normal production and don't deplete stocks of virgin material that customers have paid for.

        Just in case you don't know.
        Don't clean any electronics with it.

            The place I work uses an assortment of cleaning solutions depending upon what sort of gunk you are trying to remove. For much of the glass stuff we do, they use what is essentially windex. I've seen guys run Simple green in them as well, works great for greasy stuff especially if you can warm it up some.

            Parts should be suspended above the bottom of the tank (you likely know that) and we will often just use water in the tank but put small parts to be cleaned into a beaker with appropriate solvent in it and lower it into the water. Apparently the ultrasonic action couples through the beaker OK.

              Hope you aren't looking for results like the ones at your work. Don't run the unit dry. Depending on the gunk on the pieces it may or may not do the job.
              Have had 3 assorted brands of that style type, wife keeps hoping that the next elcheapo will work better than the others. Even with the fancy solutions from the jewelery supply. Results on her jewelry has been mediocre at best.

                PT: I don't expect much from it... It was $5.

                  Many years ago I built one from a kit. A simple single tube oscillator although the tube ran with 1000 volts on is plate at 175 milliamp. At the time my mother had a small gold plated brass belt that needed cleaning. Placed it in the tank with water and a bit of detergent and turned it on. I then got a phone call from a friend and was talking to him for about 20 minutes.
                  When I got back to the cleaner it had done an excellent job of cleaning. The belt was perfectly clean not a trace of gold left on it.

                    For degreasing, I've used Simple Green and water or Dawn detergent and water with good results. I got my three quart capacity L&R out of the dumpster behind the dental lab next door. New resistor for $0.30 and we're off. Doesn't have the oomph of a new one, but works good on small stuff.

                      I got the harbor freight version and really like it. I use a mix of household amonia and water. The amonia is a common cleaner sold in grocery stores in the soap cleaning isle. 50/50 mix seems to work great for me.

                      It is true, there is nothing free about freedom, don't be so quick to give it away.

                        I have a couple - my large unit is a 4 transducer model that is uncomfortable to put a finger into... heats the solution nice also, without a heater.

                        I've cleaned out hundeds of blocked carburetors, and zillions of chainsaw and weedeater bearings. No issues with the bearings (yes, I've heard all the retoric). Heck, I've put entire chainsaw engines into the tub.

                        Solutions? I tried than all... Most water based solutions work fine. My choice is a 10:1 dilution of purple cleaner. De-rusting - straight Evaporust. Need to clean a few items in some other solution? Put them in a thin pyrex container like a coffee pot, add the other solution and float it in the main tank.

                          I use TSP and water. Hot water works better.

                          I have used it on electronics with great success. I have a keypad on my Haas indexer and about half of the buttons would no longer function. Dropped it in the US cleaner (Branson 1/2gal) and the keys worked again.

                            Why not? I cleaned electronic circuit boards and many other electronic components in an untrasonic for years with no ill effects. You just have to use the correct cleaning solutions and wash off with clear water (preferably distilled) afterwards. A final rinse with alcohol (99% pure is best) will help dry them off. Allow to dry completely before powering up.

                            You do need to be careful of any components that may be harmed by any of the steps in this. But there are very few that will be.

                            Leftover flux can be troublesome. It can wash into switch or relay contacts or onto connector fingers and cause bad connections. It is best to rinse flux off with a flux remover solution (available in spray cans) first and make sure the solvent does not drain into any such places on the board or assembly.

                            As a side note, years ago we used Freon TF solvent to clean electronics. I once saw a photo of an oscilloscope submerged in a tank of Freon TF while operating. It had a waveform displayed on it's tube's face and all indicator lights were on. Very safe solvent for electronics, but I guess it wasn't so good for the environment.

                            You just have to use the right solvent. They make water based cleaning solutions for electronics. McMaster-Carr, among others, has them.

                              Two quick questions:-

                              Can you use kerosene [ paraffin to us ] for very dirty parts ? if not why ?

                              Secondly why not clean bearings in them ?

                              I have one of these, had it for about 5 years but it's still in the box.
                              Thinking of using it for cleaning ball nuts off CNC ball screws prior to re-lubing.
