I have a question about lc's . I have a couple I've found that are pretty smooth but you can still see some detail. Would electrolysis give me any more detail or would I be wasting my time?
go for it- it's not Curleys millions! when you connect up- if the relic isn't bubbling swap the wire around- use a paper clip if you dont have alligator clips
salt water and a 9v battery out of the smoke detector!
You have to understand the process, how to control it and what you are cleaning. Copper and bronze coins can be extremely damaged by their time in the ground. Electrolysis can remove that corrosion but it will show you the true state of the coin. You have to decide if you want a clean object or one that has the ghost of former detail in the corrosion layer.
