Vintage Copper Colander Help

Hi all!

I bought this copper colander in a pretty sorry state, but I've cleaned it up and it looks much better. The inside still looks pretty bad, so I'm wondering if our copper collectors have any advice on how to get it looking great again? Also, there is some yellowing on the outside, is this permenant damage or do I need to polish again? Where some of the polish sat around the drain holes it does look cleaner so I might need to go for round two.

I have so far used standard copper polish, and a little lemon juice on a test spot (didn't work). I've used an old sponge and a coarse washcloth.


Also I think this can be safely used for washing uncut fruit/veggies, and possibly straining pasta etc, but is this correct?

Thank you as always!
