Rescuing coins headache

Why is there really no consensus (other than don't do it) for removal of verdigris, pvc, etc on copper, silver, etc?
I'm trying to remove some pvc from circulated Buffalos, Lincolns, and IHCs.
I searched through many years of posts and there are SO MANY different responses. No one seems to be on the same page of success.
Whats worse is that when someone states they have something that works for them, another poster will come along and say "that won't work"
I feel like at some point.....there would be a recipe for success.
I know, I know,.....too many variables I guess.

Experimenting or trying different methods on "junk silver" or common "Lincoln cents" is the only way to really find out what "recipe" works best for particular maladies depending on the severity.

secrets... Acetone, Q-tips are usually effective, sometimes a rose thorn is necessary... but the more effort applied, the more likely there is already surface damage beneath. Cheers, RickO
Some posters know more than others and only give a few tips. I suggest you try ALL of them. Helps you separate the conservation buffs from the "parrots."
One method I have tried before on Buffalo nickels is two part: Coin Care then Acetone.
You'll have a very hard time prying out detailed info on copper conservation

See, what I said.. info comes out to those who listen. Maybe that's why us old copper collectors limp around.
