    I have a few copper blocks lying around that have lost their original shine, as well as collected some dust(and oil/sweat I imagine from handling) on the exterior, that's leaving dark/dirt marks when I give them a wipe.

    I have a feeling they need to be soaked in something, though I'm not sure at what kind of acid ratio the solution would be. I have to also consider that one side of the blocks have something similar to the Danger Den 'speck' finish, and am not sure if that will complicate things.

    Lastly, I wonder if I need to stop gap or block the inlet/outlets, as to not let the solution/liquid get inside?

    if you are speaking of completely external cleaning...I use neverdull, wheel polish. Does a great job with minimal effort. then you just need to clean the mating surface with alcohol after.

    I use this stuff on a lapped heatsink to give it a mirror finish.

    agreed also, the vinegar content is enough to clean it too!

    Cheap, non toxic (well relatively speaking) and cleans copper very very well:

    Slice o' lemon. Or orange.
    Anything with citric acid in it.
    I use pure crystallized citric acid (solved in water).

    Thanks.

    I had figures on maybe lemon, vinegar or even ketchup... didn't think about coca-cola.

    If I'm not going to be submerging the block(s), do I what? Rub something into the copper than leave it for...how long?

    I would suggest perhaps using a 2 part process:

    1. Submerge blocks in coke/vinegar/lemon juice for a few hours. This will remove the tarnish and grime. Rinse well under very hot water and then dry using hair dryer etc.

    2. Then use a metal polish on the exposed/easy to reach places to remove any scratches or stubborn stains.

    If you can wear a pair of rubber gloves for the second stage as the sweat/oils on your hands will cause the block to tarnish again.

    if you dont plan to clean the inside, just rub some neverdull/brasso on it . rub untill the discoloration is gone...wipe residue off with a cloth. No need for the acids and a rewash!

    Fortunatley Brasso was enough, but thanks for the other suggestions, as well as submersion ideas.
