Wondering if anyone has a good method for cleaning or somehow rejuvenating the stainless pins? Mine have gotten pretty grungy and the last couple batches of brass I have wet tumbled came out grungy, I ended up sending them through the vibratory tumbler with walnut shell media once they were dried. I just ran the pins for a couple hours by themselves with water and car wash soap to no effect They are still dull gray, not shiny like they were originally. I still have a second unopened package of the pins which I am going to switch to, but if there is some technique for making the old ones work well again, I won't throw them away. Using just the Frankford Arsenal pins from Cabela's.

If this is just something that happens to the cheaper pins, I will plan on seeking out some that are better quality next time I guess. The only reason I am still wet pin tumbling at all, is because it gives a light deburring to trimmed case mouths and also it gets rid of the resizing lube.
Do you have an ultrasonic cleaner? If so, maybe try using that to clean the pins.

Yeah, I have one. Hadn't thought of that. I will maybe have to figure out a means of containment for the pins, and test it on a sample.

<Edit> you may be using too much lemishine, I think it's something like 5cc to a quart of hot water.

After digging around try doing a tumbler cycle with simple green and hot water with just the pins to clean them. You may have to drain, rinse and repeat a few times before they're shiny again.

Use a plastic cup. Put your pins and cleaning solution in the cup then put the cup in the water in the ultrasonic cleaner. The vibration should pass through the cup and into the stuff inside.
