Review on Sparkle & Shine: The Ultimate Precious Stone Cleaner by Wendy Zhao

With this gemstone cleaner, you first remove the white cap, wet the brush and then rotate the bottom until the purple cleaner comes out, which releases quite a bit at once, so you you have to stop constantly, to roll more cleaner and when you're done you'll need to rinse the cleaner off your jewelry and brush, dry them and your brush, then put your white cap back on. It works well, but it's by no means the best jewelry cleaner, and cleaning jewelry this way is tedious and time-consuming. I think a dip solution or jewelry cleaning cloth not only works better, but also faster. For travel, this is probably a normal decision, but if it were me, my jewelry would have been cleaned prior to departure.
