Pretty sure Harbor Freight has cheap sonic cleaners... I see one in my future Not sure about Europe, but a lot of chemical labs I've been in (mainly pharmaceuticals) use them to clean stuff and degass their solvents as well. Maybe you know someone... We used to clean check valves by putting them in a little methanol and sonicate them for 10 minutes.
