OCTOPUS powerful ultrasonic cleaner, concentrate for use in ultrasonic cleaner, glasses cleaner, mechanics and printing technology cleaner (500ml)

The media could not be loaded. Used this solution with a small ultrasonic cleaner works like magic. Used with s925, 999 sliver, white gold, 18k 24k gold, gold plated, rose gold, stainless Steel they all came out clean and shiny, lab created and natural diamonds also came out cleaned and shinning. I haven't tried on natural gems and dont think i will.

Seems to be an improvement over normal. Not ace but good

Amazing cleaner,thanks.

I wasn't massively impressed by this. It works to remove dirt but it doesn't bring things up shiny, as the AI summary and some reviews suggested.

Good choice and good value

I have used the product quite a few times, and it has better results than Fairy liquid or washing-up soap.It gives an instant shine, but like everything, it takes a few cycles to get stubborn dirt off in detailse.g. gold rings with hallmarks with years of wear, making these black, but with a few cycles, it lifts the first off, leaving these marks visible.I definitely would recommend cleaning jewellery.

Not used yet.my dress jewellery needs doing desperately. At last something for those of us who can only afford costume jewellery. Keeps it looking good.

I bought this with some scepticism but needed something to enhance the cleaning power of my ultrasonic cleaner. I had a lot of uncleared Roman coins I had bought for a pittance but was getting nowhere fast. I added this at a ratio of 30 mls to 100 mls of water and put the cleaner on a 15 minute cycle at 30 degrees C. The result was amazing, and after two cycles and a quick rinse in water I had clean identifiable coins. One or two more heavily soiled coins needed a third cycle, but overall…..WOW!! Much cheaper buying uncleared coins and there’s also the excitement of discovery when cleaned. Among these Roman coins were two Celtic units and a Henry VIII groat !
