Thread: Sonic cleaners

I'm interested in the sonic cleaner route also.
It seems simpler but I'm wondering why you go back to the corn media tumbler for a second clean ?
Does the sonic cleaner miss something?
1.5 liter seems a good size

I have an ultrasonic cleaner. About 1.8L capacity.
I use 1.5 L of nearly boiling water, 2 tsp of citric acid (cheapest house brand) and 2 tsp of dishwashing liquid.
Its maximum cycle is 8 minutes. For the first couple of loads this is sufficient. Subsequent loads need a 2nd cycle.

After ultrasonic cleaning I oven dry the cases at 120 C for 10 minutes and then allow to dry on a clean towel.

The cases don't come out shiny but do come out clean. I never have to separately clean primer pockets.

The residual dirty water goes on the lawn.

The reasoning for the media tumble was only to remove case lube, if I do a bump or f/l resize and also if there was any water left in the case this would get rid of it.
Presently trying out the lee collett die so no case lube ( or going into media tumbler ) untill a case bump is indicated


This photo shows a small improvement on the cases.... admittedly they are once fired and have been tumbled on a corn media tumbler prior to this but I was impressed how it ( the sonic ) removed the annealing colour band
