Jeweler’s Secret Jewelry Cleaner uses an advanced “foaming action” formula that cleans jewelry without using damaging substances or abrasives like ammonia, bleach, or the old standard: toothpaste. Unlike traditional jewelry cleaners and dips, Jeweler’s Secret’s foaming action quickly breaks down oils (skin oil, hand lotion, everyday build-up and grime) without using any harsh chemicals that can cause scratches or even “pit” fine or costume jewelry. Jeweler’s Secret cleans and restores that “like new” look and sparkle to diamonds, precious, and semi-precious stones. It cleans gold, silver, platinum, and costume jewelry. Most ordinary “dip” jewelry cleaners require you to soak your jewelry overnight and after just a couple of cleanings, you are soaking your jewelry with all the dirt, build-up, and grime from previous cleanings. In addition, these “standard” formulas use ammonia-based cleaning agents that over time are harmful to your jewelry. Jeweler's Secret Kit (2 -3.4 oz Bottles Polishing Cloth Brush) Safe to use.
