At first i doubted whether such a small device could deliver real cleaning effect. after weeks of real‑world use, my worry is totally gone. grease stuck in eyeglass hinge, dark smudge on ring setting, milk residue on pacifiers, all these common household mess get handled well. when the item is extra dirty, adding one tiny drop of mild neutral soap into water will greatly boost cleaning result. the machine will turn slightly warm after multiple continuous cycles, i suggest letting it cool down for a while before next use.
