If I were you, I would experiment.
You obviously have quite a few pennies with problems. These coins will never get back to 100% of mint fresh and probably are not that valuable since they are in need of cleaning.
What works? Try anything you want - so you will know what to avoid. Copper polish or any other substance with the word polish in it is probably a good thing to avoid.
If your not sure about something, dilute it.
Use your new techniques on coins that are common so your not destroying coins that are valuable even in a corroded state.
We all have to learn and this learning makes us smarter not only on what the cleaning process does to coins but also to recognize coins that are offered to you - have they been cleaned?
