Jewelry Cleaner
Hydrogen peroxide is also known for its cleansing properties, and it could just provide the solution to maintaining your jewelry. Its stain-fighting abilities are what you need to clean your platinum, silver, and golden jewelry.
Create a cleaner by mixing a few drops of the chemical compound and baking soda. Rub the resulting paste gently on your jewelry, rinse, and wipe dry. It rids them of dirt, body oils, and any other grime stuck on them. You could certainly buy a cleaning solution specifically formulated for the job, but hydrogen peroxide is much more inexpensive.
