Hi what Cleaning Fluid etc do members use in thier Rotary Wet Tumblers what do you use ? And in what amounts ?
Cold water, a decent squirt of any washing up liquid and 1/4 to 1/2 teaspoon of citric acid (if you have hard water), that's in a 7L Frankford Arsenal tumbler.
Don't add more citric acid, it's not for cleaning just to soften the water to help the pins do a better job.
Although I’ve yet to do it in anger apparently citric acid and car wash n wax work very well!
See this thread, Brass cleaner
... or we'd just use fabric conditionerHow does softening the water aid the mechanical cleaning carried out by the pins?
12 years surely?
Makes sense on the softening the detergent if the detergent is sensitive to hard water but as I say I see literally no difference between cases tumbled with washing up liquid and water or the same with citric acid.
I use a 3 drum rock tumbler, will do one drum with citric and one without, post a photo and see if anyone can tell the difference
The citric acid is a mild pickle so will be aiding and speeding up the removal of the tarnish. The stainless pins have a predominantly burnishing action rather than an abrading one. So something cutting back the oxide film can only help.
If you just put the brass into a citric acid solution without tumbling it will just come out matt/dull yellow. No tarnish, but no shine.
Many washing up liquids contain citric acid which helps soften hard water and cuts through fats. The USA dishwasher additive Lemi Shine is citric acid and is touted to prevent hard water marks. But its main advantage for us reloaders is that it deodorises.

PS Whilst I was writing this you have added your "with and without experiment"...the main difference will be in the speed of achieving a similar result, not in the difference between the results.
I had considered that but if they are tumbled for the same amount of time then if the cases with the citric come out cleaner it will show the citric acid is speeding up the process.....
