Lakeland Sonic Jewellery Cleaner 5 "Brilliant" Mrs Roby 10 September 2015 I was surprised to see a one star review for this item, I love it. It won't remove tarnish, but does a great job on dirt. I regularly clean my rings, and chains. My two daughters frequently bring their jewellery to be cleaned as well. I put in a tiny amount of washing up liquid with warm water. If not clean enough on the 180 setting, it goes in for another zap. A waterproof watch has also had the treatment. This has an expending bracelet and it was surprising how much grime accumulates in there. I plan to buy another to give as a present.
