Humphrey’s Tool of the Week this week is The Ultrasonic cleaner. And here is Humphrey doing a really good impression of what it would feel like inside the ultrasonic. How it works is all very scientific and technical and involves “implosions” but when Humphrey explained it to me I went and made a cup of tea and decided I liked the idea that it was magic instead. You put water, ultrasonic cleaning fluid and your jewellery inside it and turn it on and voila! It magically cleans all the polishing compound from your jewellery after polishing as well as the soapy, dirty gunk that accumulates in jewellery when it’s worn. woof!
