Sonic cleaner - before and after (links inside)

Here's a couple of nuts/bolts I ran through my sonic cleaner that I normally use for cleaning brass for reloading:

Using distilled water, about 20 minutes of run time and a tablespoon of Brasso.

Also, with sonic cleaning you also need to remember to not put soft aluminium alloys in - they won't appreciate being hit with a zillion tiny sonic hammers!

The other thing to realise with a lot of the parts, gunge/dirt will sometimes appear to remain attached - but will be softened and usually wipes off with a rag, the parts can then be cleaned with additional cycles through the cleaner.

I thought that ultra sonic cleaning was one of the primary methods used to clean carburettors, of which are made our aluminium? Quite a difference there! The unit I'm looking at is an industrial unit and large enough to take a rack of assembled in-line 4 carbs

What about barrels and a head though too?

I would imagine it would depend on factors like how soft the aluminium alloy is, and the power/frequency of the unit concerned?
