I've used this jewelry cleaner for about 35 years. I love that you can put any kind of jewelry in it, costume, solid gold, silver, any gem stones. It all comes out sparkling.
I have been using Jewel Brite in my ultrasonic cleaner for over 20 years. It works so well that I usually don’t even turn the cleaner on, just let my rings soak overnight and in the morning they sparkle. No ammonia, pleasant odor, gentle to my skin. Great stuff.
