Cleaning coins, nuts, bolts & other small metal items

Postby smidsy » Fri Jan 17, 2014 3:21 pm

What do you recommend is the best method of removing tarnish etc. from sixpence coins.
I've tried soaking them in vinegar, bleach (with some success), soda crystals and paint thinners. I have quite a few that are really blackened, and don't look good in the jackpot window or escalator.

Any advice is appreciated. !PUZZLED!

Coca Cola. The cheaper, the better.

Thanks for the cola tip.
It might work well with copper coins, but not much success on sixpences. Didn't even go for the very cheap cola (17p ltr)
tried the expensive 42p ltr :D .
Soaked overnight, some of the tarnish on some coins has come off.

Going to try a sonic cleaner borrowed off a friend. Don't know what to use in it though.
Any other ideas !PUZZLED!
Thanks..

Some sixpences were real silver and they tarnish to black so something like Silverdip might do the job.
An old jeweller friend of mine used to clean jewellery by lightly simmering it in Bold washing powder for about five minutes. My wife occasionally cleans her engagement ring this way and it certainly makes it sparkle. If you try this on jewellery make absolutely sure that any ‘stones’ are not plastic or glued in.

Try the chrome polish stuff
It's in a gold brown ish tube
Think it's called autoglene or nr that
This stuff removes rust easy
So sure it will shine them

Thanks for the tips. The sixpences are all after 1947, so cupro nickel.
Tried 'Dirtwash' metal polish, only seems to polish the high lights and doesn't clean all the surface.
Think it may need some kind of acid, so back in the drawer for now.

Cheer's for the advice.. :D

Sounds more like you are having a BBQ than cleaning........
Could just buy a load of 1967 new uncirculated sixpences, then sell the sixpences you have on ebay - difference in cost but save you all the elbow grease & cost of the metal polish.
Or you could invest in a vibrating tumbler and use that instead.

I use an old dental ultrasonic cleaner for degreasing metal for home plating. This one is designed for cleaning coins with this cleaning fluid. How effective it is, I can't say. Another method would be electrolysis. It should be said that all of the methods suggested so far are unsuitable for rare/valuable coins.
Coin Cleaning.

I think aristomatic is right - if you must have shiny, save yourself a lot of bother and buy uncirculated coins.
