Ultrasonic

Hey

How much is enough liquid to clean watch parts. I mean is a machine that takes 2 litres Big enough or is 3 litre better? 

Or are other things more important like frequency temp etc. 

Cheers

Umm wow 2 liters is wayyyy too much, you would be going through cleaning fluid like water on a hot day. I use small mason or glass jars with lids, maybe 4-8oz tops. I have different sizes. Bigger jars for main plates bridges, and smaller for wheels arbors, and i use separate jar for the barrel since there tends to be lots of grease and old oils in those I don’t want it contaminating the fluids for the more important parts jars. I have 4 of each size so i can do a 3/1 or 2/2 clean/rinse ratio. I stop cleaning when fluid remains clear. So use smaller amounts with more cleanings, you get a quite a few cleanings from each jar. As the first jar gets dirty I dump or filter if i can then i make the final cleaning jar my new first cleaning jar. I also put little mesh parts basket inside the jars. Now when you do this you need to fill the ultrasonic up with water at a bite higher level than the fluid in the jars but not too high where they will float or bobble. Frequency is important but doesn’t have much to do with size it all depends on the quality of the ultrasonic. There are larger ones out there with high frequency but they are really not needed and are extremely expensive. Get smaller ultrasonic with high frequency at an affordable price. Jewelry ultrasonics are good for this. I use them to clean tattoo equipment as well which will easily remove old bunked up ink in the crevices of the tubes.

Hi Gary Unless you are cleaning clock parts 2ltrs is as big  as you go, as mentioned jewelery cleaners at high frequency  are ok. Cleaning fluids Naptha ,Benzine. Isopropyl are expensive in quantity therefore the small jars in the machine containing the cleaning fluid are the sensible and economic way to go.  There are many opinions on the use of ultrasonic cleaners as there is fluids and cleaners you will get many of them on here. how you do it is down to you in the end.

Principally multiple transducers, multiple frequencies and heater are all useful options.

You need small GLASS jars with metal lids that seal well for cleaning solutions.  These are placed in the ultrasonic tank partially filled with water to conduct the sound energy.

Good Luck,
