"My sterling jewelry was tarnished. A polishing cloth didn't clean it. So I tried this recipe. Wow! Amazing, inexpensive... Does a great job! You'll be wowed too! Works on other metals and is safe for stone jewelry too. Don't reuse the cleaner; make a new batch each time."
The jewelry cleaner works on gold-filled, brass, German (nickel) silver, and sterling silver. I cleaned jewelry with freshwater pearls, mother of pearl, turquoise, onyx, and amber. The patina that is desired in the grooves of vintage jewelry stays intact.
