      Hi.  As a former Plumber, We use to something called "self-cleaning flux" when We soldered pipes together.

       It was great at removing scorched areas of pipe, corrosion, & most other things that coat a piece of copper so it could be sealed water-tight again.

       Just be sure to wipe only a small amount onto the penny & scrub with a soft cloth to keep the information intact, & wipe it off within 2-3 hours of using it. Maybe even rinse with warm water afterwards, but shouldn't be necessary.

       It's designed to be used with high heat (a torch) so possibly a hair dryer might help before scrubbing, in the melted form it dissolves the staining stuff quicker.

               G'Luck!!!

    The water that gets dirty as cut flowers sit in it often create chemicals that clean copper pennies.

    Before cleaning it you need to look at it with a jewelers loupe, or really good magnifying glass. Cleaning = devaluation.

    Buy some copper cleaner at your local grocery store, Walmart, Target, Ace Hardware, etc. I will make the penny bright and shiny and won't harm it.

    Pen erasure (meaning the blue part of the erasure.) cleans them up quick and fast.

    You will lose any value if you try to clean it. If just for your use try copper cleaner.

    It depends on what your purpose is.  If you want to keep it as a collector's item or investment, you don't (or take it to a professional).  If you want a nice shiny penny for yourself, there are various solvents that you can use.
