I know the adage of never clean coins..... but....some that are low value and so poor that you cannot even see the details, surely are ok to carefully clean?
I have had some success with electrolysis using graphite anodes and distilled water with baking soda in a double sandwich cableless format and two small circulating pumps.
Does anyone else have any input experience on this. When researching this process I notice in the worlds top museums use this process to remove/reverse corrosion on metal items so it must be the best way?

@dog, if you use the keyword ELECTROLYSIS in the CCF search box, you will find many interesting prior threads on this subject. To get you started, here are links to a couple:

I tried it once. At low voltage it bubbles away but does nothing noticeable to the coin. At higher voltage it damages the coin even more. I don't recommend wasting your time.
