This very small, tabletop jewelry cleaner is inexpensive and easy to store. It holds two or three small jewelry items, or a pair of glasses, but not much else. You also want to be careful to not overload the small cleaning tub, because jewelry can get tangled or damage each other during cleaning. You also don't want to use it on soft gemstones or pearls, any stone with a visible inclusion (the heat could cause it to split), or costume jewelry.This is pretty fast, only taking a couple minutes for its cycle. You can buy cleaning solution or easily make your own with hot water (preferably distilled), a dash of ammonia and a tiny amount of dish soap. You can also use hot water only, but it won't be quite as effective. After cleaning you want to rinse your jewelry with cool tap water, to remove loosened dirt, and dry completely.This doesn't have any settings, it's one size fits all cleaning with a short cycle (the instructions say five minutes, but it's much shorter than that) that can be repeated, if needed. It doesn't heat the water, so make sure you put it in that way (you want it hot to the touch, but not boiling) and it makes a bit of noise, though not much. It left my rings sparkling and seemed worth the small investment of time and storage space. Low hassle and good results.
