Homemade Jewelry Cleaner, Hack or Hoax?

We explain why using toothpaste as a homemade jewelry cleaner can do more harm than good.

In addition to cleaning your teeth, toothpaste has been lauded as a DIY remedy for everything from making your nails grow to getting rid of acne. But can toothpaste be used to safely clean jewelry?

Despite what you may have heard, this is a complete hoax. It is not recommended that you use toothpaste to clean your jewelry as you may end up permanently ruining its luster and overall integrity. It’s better to use a jewelry cleanser specifically formulated for safety and efficacy.

“Never use toothpaste to clean your jewelry. The abrasives in toothpaste can scratch the surface of gemstones, cause chemical reactions with metals, and damage the integrity of your jewelry.”

Toothpaste Is Too Abrasive to Safely Clean Jewelry

Dentists and jewelers alike agree it’s always best to use products for which they are designed. Toothpaste is an abrasive that contains calcium carbonate and modified silica, agents used to break up food debris found in your mouth. Abrasives can damage jewelry because of their chemical composition, measured by the Mohs Scale of Hardness.

Mohs Scale of Hardness

Mohs Scale of Hardness was developed in 1812 by Friedrich Mohs, a German mineralogist. The Mohs Scale of Hardness provides a measure of a particular gem or mineral’s resistance to being scratched. The scale ranges from 1 (least hard, talc) to 10 (most hard, diamond). It’s best used to determine durability, meaning how a gem or mineral can withstand abrasions.

According to Science, Toothpaste Can Harm Jewelry                               

Experts rate many toothpastes between a scale of 2.5 and 4 on the Mohs Scale of Hardness. The abrasives in toothpastes, which according to the American Dental Association, are designed not to dissolve in water, can scratch the surface of gemstones and metals like gold and silver.

Some toothpaste formulas also contain Sodium Lauryl Sulfate (SLS), which makes it a detergent. However, SLS has little cleaning power and is used in toothpaste for its foaming properties. Other common toothpaste ingredients include fluoride (including sodium fluoride and stannous fluoride) and baking soda (sodium bicarbonate) which can be corrosive to metal. Hydrogen peroxide, a chemical lightener is another common toothpaste ingredient, which can be reactive with metals and semi-precious stones. Finally, gums, favoring agents, and non-sugar sweeteners are common to toothpaste formulas, which might cause chemical reactions with your jewelry. Opals and pearls, two of the most porous precious gemstones, will permanently lose their color and sheen if they come in contact with toothpaste.

You’re better off sticking with a non-abrasive jewelry cleanser specifically formulated for the metals, gem and semi-precious stones of your favorite baubles.

Silver jewelry has its own unique maintenance needs, especially considering tarnish that builds up over time. What is the best way to clean silver jewelry? Here are our top three recommendations for cleaning both sterling silver and other silver jewelry:

Connoisseurs Tip: Silver actually tarnishes most easily sitting in a jewelry box. Constant friction from everyday wear, on the other hand, helps to create a natural polishing effect. When you’re not wearing your silver jewelry, wrap it in a Connoisseurs UltraSoft® Jewelry Polishing Cloth to slow down the tarnishing process.
