2023 Ultrasonic Jewellry Cleaner Portable and Low Noise Ultrasonic Machine for Jewellry, Ring, Silver, Retainer, Eyeglass, Watches, Coins, 350ML, 46KHz Ultrasound Cleaner Machine by Kunphy

Have tried several things in this. A watch, glasses (spectacles), and jewellery.Glasses - OK but not as good as running under hot water with shower gel (used hot soapy water in the device)Watch - Great. It really cleaned the areas I can't get to.Jewellery- pretty good for my rings and earrings.I'm divided as to whether this devise is worth it. If you have lot of jewellery, then yes. It will get to the small crevices. For spectacles, stick to the shower gel.

I performed a test clean of my Apple Watch Milanese Loop. I was impressed with the amount of dirt extracted from it. Very pleased so far.

Nice little compact machine, cleaned up my earrings and rings nicely.

Works OK get what you pay for

The media could not be loaded.  I was amazed at the filth coming from my glasses. I thought they were clean! 😳

Broken after less than two weeks or use

Unfortunately I have just tried to use this, having bought it at the start of the year only to find it won't turn on. Rating may have been different if it had workedUpdate - have been offered a replacement and a full refund. Sadly neither have appeared

This simple t use device just plugs into the mains with the supplied power adaptor and then when switched on runs for 3 minutes. For jewelry that needs a proper clean then put just over 300ml of warm to the hand water in the "bath" then a couple of drops of a good quality detergent in (e.g Fairy Liquid - other products are available(!)) Just put your ring (s) in the bath, or perhaps bracelets , or in fact any metal jewelry that needs brightening up . Don't overdo the detergent or you will get an overflow of bubbles - literally one or two drops are enough. After 3 minutes it powers down - just look at the jewelry and if you think it isn't quite ready than turn on again for another 3 minutes. Most jewelry is clean after one or two cycles. I cannot stress how improved a ring is after this process.Why have one of these anyway? Well- the idea is to have a place to clean your jewelry gently with no damaging or corrosive substances, and this just gives you a definite place to perform the clean and this also vibrates very fast and offers an ideal solution. I would avoid any alcohol based solvents - a tiny amount of detergent works well.This is an excellent idea for someone who wants to keep their jewelry sparkling and good value too!
