Well the washing up bowl with hot water and Fairy liquid made a big difference but the 20p pieces are sill a little oil covered (and still smell of the stuff) and some swarf is still there. Some of it might be ferrous not brass.
Any tips?

There's a story here which you're not telling us!

£120 of 20p coins and a cordless drill.
You lost the key to the puggy?

I would try a bit of IPA or acetone as they would remove oil and water-based material, followed by washing in water.
Spend them and let somebody else worry about it! I would have thought it would wear off in time. I assume you have tried coka Cola... Brian
Yes the mind boggles to be honest. Why only 20ps? They are one of the few coins we use which are non ferrous. I have 1, 2,
5,and 10p pieces, some of which you can pick up with a magnet, and some you cannot, but the 20ps are never magnetic. Brian

Washing soda.
They weigh 5 grams exactly. You could sell them as weights.
I did ask her but she gave me the cold shoulder:-)
Good to know she's not a scrubber then.
Ask your bank to exchange them for you? They can send damaged coins back to the mint for replacement.

Petrol is about the cheapest decent solvent for most oils.
Detergent, solvent or mechanical. Detergent: most will work. If not wul, try something else. Solvent: planty to choose from. I tend to prefer paraffin. It's cheap, thin, safe, still usable with the added oil, and traces left evaporate off in a few days. Mechanical: paper is all that's needed. The end result will burn nicel.y

Use them in a supermarket self-service till ?.
Save the non-magnetic ones, Brian. The way inflation is heading they will be worth more as metal than their face value.

Ta. I have some for the genny at work.
Washing machine?
be vigilant with those. If you chuck in a few handfuls of 'copper' then it will undercount. You need to drip feed them in slowly.
