2-100 clad coins days - how do I clean them?

Hi all, I had a very nice weekend, two of the days had over 100 clads each day, plus all kinds of other goodies. I tried the white vinegar I've seen recommended on here by some. I put the coins in a jug, poured white vinegar over them, let it sit 24 hours. Rinsed them in water. It got the dirt/grime off them, but turned them a green color. I did find a 64 rosey that was really dirty, but clearly silver after the vinegar step. Did I let the coins sit long enough in the vinegar? Should I do something else? I've seen that some people use baking soda, though I don't know how to mix it up. Any advice would be greatly appreciated, thanks!

Here is what I do. Separate the clad into quarters and dimes, nickels, pennies . I use a 3lb Harbor Freight rotary tumbler. Cover the clad with vinegar and add a few tablespoons of salt. Tumble for 30 minutes. Save the fluid into a separate container. Re-tumble with hot water and a shot of dishwashing soap. While the tumbler runs I pre-soak the pennies with the saved liquid. I also add a handful of small round gravel. The pennies have to be run separately and the same with each group. Works great for me.

Labor Day Treasure.jpg I clean my clad the following way and it works pretty well............ First, to get the dirt off them I tumble the coins in aquarium gravel with water and a bit of dish soap for about 45 minutes. Then removing the pennies, I rinse them and then submerge the coins in a dish of vinegar and salt and stir them around for about 5 minutes. Then I rinse them in water and tumble them again for an hour. Most of the coins will come out looking pretty good but there will always be a few that stay dark due to length of time in the ground and soil conditions. Do not tumble the coins in the salt vinegar solution and don't put pennies in the salt/vinegar. The coins in the pic were cleaned the way I described and were dark brown before I cleaned them.

My method works really good. These coins are just coins going back into circulation. Explain why one should not.

If you put the pennies in the salt and vinegar they turn an ugly orange color. I've read a few posts here where the one who posted said they tumbled the coins in the salt and vinegar and it blew the lid off the tumbler.....I based my statement on other's experiences.
I have had the drum swell and stop the drum from turning and have had the lid push off. The way I found to stop that was to only fill the drum less than 1/4 full of clad and use just enough vinegar to cover the clad. Then watch it fairly close. No more than 30 minutes with salt and vinegar in the tumbler. My pennies are not an ugly orange. The copper pennies look great and the zinc coins look like crap, but they were crap to start with.

If I put the pennies in the salt/vinegar they always come out ugly. Maybe my mixture is different than yours and is a bit too strong.

To be honest? I just put the coins Minus the Cents in very hot clean water and a bit of dish washer detergent. It does not suds up so bad. Tumble for a few hours, dump out dirty water through an old colander. Add new same treatment and repeat. After a few treatments they are clean. I always do the Cents separate, Beale.

Here is a batch of pennies that just finished up. These were presoaked in salt/vinegar for an hour while waiting on the tumbler to get free. Tumbled for 30 minutes in salt/vinegar. Next round was hot water with some baking soda to nuetralize the acid then tumbled in reptile bedding media(crushed walnut). When the load is this large you have to de-gas the drum every 5 minutes.

What's your ratio of salt to vinegar for the pennies?
