Cleaning copper

[paul connor]

I have a rare wade proof distributor where the HT contacts deep in the bakolite are green and horrible.

What can i pour and leave in there that will not affect anything, yet clean the copper without aggitation? As there is no way to actually clean then mechanically.

 

any ideas?

Vinegar.  8-)

Thanks, Gordon.

I have left it soak overnight, let's hope it does the trick! 

Hope you're well and keeping safe in these turbulent times.

Thanks

Paul

Managing well so far Paul, hope you are too.  Depending on how thickly covered it is you may want to leave it for days, with a little light poking / brushing so it can get right in there.

If you suddenly develop an overwhelming desire for fish and chips I'm taking no responsibility.  😁

hydrochloric acid (brick cleaner) is excellent and will clean the copper like new in seconds but it will dissolve aluminium and also zinc from brass so use it wisely

You could also try coca cola, which contains a reasonable amount of phosphoric acid and citric acid...

An old home remedy for cleaning Chrome IIRC

I have used a household cleaner called Cillit Bang and that works well.
