A little gray cloth and five minutes at the kitchen sink is often all it takes to bring a piece of jewelry back to life. Gold and sterling silver each pick up grime differently, and silver in particular reacts with the air around it, so the two metals need slightly different routines to stay bright between wears. Below is a simple, dermatologist-safe (and jeweler-approved) approach to cleaning both metals at home, plus what to avoid so you do not damage stones, plating, or settings along the way.

Gold, especially higher-karat gold, is fairly inert. Everyday dulling on a gold piece is almost always a buildup of lotion, oils, soap residue, and dust rather than a reaction with the metal itself, so a gentle soak and rinse usually restores the shine. Sterling silver is a different story: it is 92.5% pure silver alloyed with other metals for strength, and that silver reacts with sulfur compounds in the air (from things like rubber, wool, and everyday pollution) to form silver sulfide, the dark film we call tarnish. That is a chemical change on the surface of the metal, not surface dirt, which is why silver needs a slightly different approach to bring the shine back.
This method works for solid gold, gold-filled, and most gold-plated pieces (just skip the brushing step on thin plating, since it can wear through faster than solid gold).
A light clean every one to two months keeps gold looking its best, with a deeper soak every six months or whenever a piece starts to look dull.
For light tarnish, the same gentle soap-and-water soak used for gold works well: a few drops of mild dish soap in lukewarm water, a five-minute soak, a soft toothbrush for detail work, then a cold rinse and a soft cloth to dry.
For moderate to heavy tarnish, the baking soda and aluminum foil method lifts tarnish through a chemical reaction rather than abrasion, which makes it gentler on the metal than polishing it off by hand:
A gentler alternative for delicate pieces is a soak in half a cup of white vinegar mixed with two tablespoons of baking soda for two to three hours, followed by a thorough rinse and dry. Skip the baking soda methods on silver-plated pieces or anything with a high-polish finish, since baking soda is mildly abrasive and can scratch a thin plated surface.

How jewelry is stored has almost as much impact on tarnish and dullness as how it is cleaned. Humidity, light, and airborne sulfur compounds all speed up tarnish on silver, so the goal is a cool, dry, dark spot with as little air exposure as possible.
Home cleaning covers most everyday maintenance, but a few situations call for a professional instead: heirloom or antique pieces where the setting or plating may be fragile, jewelry set with emeralds, opals, pearls, or other soft or treated stones, and anything with tarnish so heavy that a home soak does not touch it. A jeweler can also check prongs and clasps for wear while cleaning, which catches loose stones before they are lost.
A light soap-and-water clean every one to two months keeps everyday gold looking bright, with a deeper 15 to 30 minute soak every six months or whenever a piece starts to look dull.
It is best to avoid it. Toothpaste is a common home remedy, but it is abrasive enough to leave fine scratches on both gold and silver over repeated use. A mild dish soap and warm water soak is gentler and just as effective for everyday grime.
Line a bowl with aluminum foil, shiny side up, place the tarnished silver on the foil, then add boiling water with one to two tablespoons of baking soda per cup of water. The tarnish transfers onto the foil within 5 to 10 minutes through a chemical reaction, then you rinse and dry the piece.
The mild soap and water soak is safe for most gemstones, but skip baking soda methods and ultrasonic cleaners on emeralds, opals, pearls, and other soft or treated stones, since they can crack, cloud, or lose their treatment under abrasion or vibration.
Store silver in a cool, dry, dark spot away from humidity, keep pieces in individual pouches or lined compartments, and add anti-tarnish strips to absorb the sulfur compounds in the air that cause tarnish in the first place.
A basic mild soap and warm water soak works for both metals at the same time. Save the baking soda and foil tarnish method for silver only, and clean gold and silver pieces separately during that step since it is designed specifically for silver tarnish.
