Coin tumbling question…

[KSDfisher77]

I use stainless steel pins & a rotary tumbler with 2 drops of dawn ultra dish soap & a 9mm case full of Lemi-Shine. Tumble the pennies separately.

Tumble the pennies separately.

I found out early! I was horrified at all the pink clad.

This has been bugging me for years and have never been able to find a good answer
Tumbled some clad today and as usual
They came out like this (red patina)
No coppers mixed in
I know it spends but am curious if any one found a way for them not to come out like this.
Aquarium gravel and pine sol used today

I always tumbled the clad with sand and nothing else for 3 hours... plenty of water. I then emptied water and added a couple tablespoons of aluminum jelly and tumbled for a few minutes more. Rinse thoroughly under COLD water and dry right away. Exposure to air or heat when wet turns them red again, so dry them right away. This works with turning your old nickels grey again. Take care
Mike.

I was doing s batch of clad quarters and they came out PINK !!! I checked the batch and no pennies. I used vinegar & salt way back when. Then to shine things up, I used lime juice.
Usually worked well with removing the pink. On one occasion nothing would remove the pink. Turned out one side of the clad quarter had split off and there was the copper core turning everything pink. Try the lime juice in water and run over night. Im using stainless steel shot nowadays and everything comes out shiny and new. May have to do a few runs to get the red to lighten up. Also, a squirt of Lime-a-way in water is my new 'go to' cleaner for coins. Give it a try.
