Review on Blitz 653 Gem & Jewelry Cleaner Concentrate - 8 fl oz Tall Bottle, 6-Pack by Katie Miller

I ended up buying 6 packs to save money but 1 bottle is more than enough. You have to dilute the cleaner with water and end up with 1 part cleaner to 5 parts water. I don't have a lot of jewelry and my ultrasonic cleaner is pretty small so I hardly used it. Since I have 6 bottles, that's enough for a while. In terms of cleaning, it does its job quite well. I think this works well with gold but it may be different with other metals. Maybe my jewelry is pretty old and I haven't cleaned it in a while, or it just lacks compared to how well it cleans gold, but overall it still works great.
