There are a few different video tips on youtube on how to clean old coins, but none of them seem to have really old oxidized coins, so I thought I would see if the same tips work on older coins. I used what I could find in the cupboard which was baking soda and vinegar. You can use either bi carbonate of soda or baking powder. After a few hours I ended up with the results I wanted, so that means all the youtube tips do really work, but just give it a bit longer for really old oxidized coins. Incidently, since I have just had fibre optic broadband installed, this video uploaded before I even finished typing the description. Way to go 👍
