I want to clean my engagement and wedding rings at home. They're platinum and diamond and seem to be full of suncream and just a lot less sparkly than they used to be.
Googling suggests a variety of methods; washing up liquid in warm water with a soft toothbrush, toothpaste, vinegar?
We live hundreds of miles away from the jewellers my DH bought them from so I'd like a DIY method if poss.
Any suggestions greatly received.
