Wet tumbling

[Jeffo1960]

Been doing the above for a good while but I am noticed recently my brass are coming out tarnished, like a smokey grey, so I am guessing my pins need to be degreased, any suggestions thanks in advance 

[John MH]

Boil the pins in hot soapy water and rinse with clean hot water, that should ‘degrease’ them.

[Jeffo1960]

Thanks for that will do it tonight

If you are re-sizing before tumbling, usingf a waster based case lubricant like RCBS Case lube-2 will solve the problem

 

Cheers

But I never had this before it has only just started and its getting worse, thinking about I did change my lube, as my mate give, me some he had left over, cant remember what it was as finished it, and threw the container 

[Jeffo1960]

I boiled the pins as John MH advised, and scrubbed the drum, took a bit of elbow grease, tryed it and it's all good back to nice clean brass, also going to try, RCBS Case lube 2, as suggested, thanks again

What are you using to clean your brass. As in detergent wise ?

[Jeffo1960]

Bit of washing up liquid and some cheap car polish

Forget the car polish, a squirt of w/up liquid and a 1/4 teaspoon of citric acid crystals (off Ebay) to help soften the water and they'll come out nice and clean.

I de-prime my cases then my larger F/A tumbler takes about 30-45mins to run an initial clean (using 1.5mm steel ball bearings).

That gets the cases more then clean enough to re-size, prep and inspect before a final 30min clean.

Same as @phaedra1106uka squirt of w/up liquid and a 1/4 teaspoon of citric acid crystals (off Ebay)

Anyone tried leaving out the pins to avoid peening the chamfer?

[phoenix]

AFAIK, it's the pins that actually do the cleaning.

There might be some cleaning action on the outside of the cases with the brass rubbing against each other but that won't clean the primer pockets or the inside surface of the case.

Deburring and chamfering after wet tumbling solves any peening issues.

1 Finish dishwasher tab and a good squirt of rise aid job done , no stains , no tarnish

I have never had greasy pins I just rinse everything off in cold water and put it away .

This worked a treat for me.
