Jewellery Cleaner to use at home

[70isaLimitNotaTarget]

What do you recommend?
I need one for gold and silver (most gemset)
I've got one of those little white battery ones that you put liquid in and it goes zzzzzzzzz

But I've just taken an eternity ring out and it's still all claggy. (And the batteries have gone flat . I'm not inclined to buy 4 new batteries , it's pants)

So. I'm thinking of one for my Christmas.
I don't wear rings at work but I do wear earrings and of course they get all soapy.
And DD now has pierced ears.

TIA

John Lewis do a little pot of jewellery cleaning liquid with a basket you put your rings etc in to suspend then in it. You just leave for 20 mins or so, then rinse. There's a tiny brush attached in case anything needs a quick scrub. No electricity! Works brilliantly and just a few quid. It's similar to one the posh jeweller we bought my engagement ring gave me. It's stocked in the cleaning products bit of their kitchenware dept. (My mother used to clean her jewellery with gin! )

Nothing is better than Stardrops, small amount in a little cup add water to make a solution, use a soft tooth brush to gently scrub the solution on to the ring.

I'm jeweler :-)
