TL;DR
Tarnish is a chemical reaction between silver and sulfur compounds in the air, so the whole strategy is to keep air away from the metal. Store silver clean and completely dry, wrapped in anti-tarnish cloth or acid-free tissue, in a drawer or chest away from humidity. Good storage cuts polishing to once or twice a year instead of before every use.
What Tarnish Actually Is
The black or yellow film on silver is silver sulfide. It forms when silver meets sulfur-containing compounds in the air, which are present everywhere in trace amounts and rise sharply near certain materials and foods.
It is not dirt and it is not corrosion eating the metal away in any meaningful sense. It is a surface compound, and polishing removes it along with a very small amount of silver each time.
That last point is why storage beats polishing. Every polish takes a little metal, and on silver plate, where the silver layer is thin, repeated polishing eventually wears through to the base metal. The same logic applies to copper, discussed in should you polish lacquered copper cookware, and the wider material rules are in the guide to cookware and glassware care by material.
What Makes Silver Tarnish Faster?
Humidity, sulfur-containing materials, and direct contact with certain foods all speed it up. Rubber bands, wool, felt, newspaper, latex, and some woods release sulfur compounds. Eggs, onions, mustard, mayonnaise, and salt all attack silver directly, and salt is the worst if it is left on the metal.

Humidity is the multiplier. In a damp Oregon winter, silver stored in an unheated room or a basement tarnishes noticeably faster than the same set in a heated interior drawer.
Air pollution and gas appliances raise the sulfur load in a home as well, which is why silver kept in a kitchen tarnishes faster than silver kept in a dining room cabinet.
How Should You Store Silver Flatware?
Wash and dry each piece completely, then wrap it in anti-tarnish cloth or acid-free tissue, or lay it in a flatware chest lined with tarnish-inhibiting fabric. Keep the storage in a dry interior space, not a basement or a garage. The goal is a barrier between the silver and the air, plus low humidity.
Do not wrap silver in plastic wrap or seal it in a plastic bag directly against the metal, since plastic can trap moisture and some plastics off-gas.
A resealable bag with the air pressed out is acceptable if the silver is first wrapped in anti-tarnish cloth or tissue. The cloth is the barrier, not the bag.
Things to Keep Away From Silver
Rubber bands are the classic mistake. Rubber releases sulfur and will leave a permanent black band across a piece within months.
Newspaper is another. The ink and the paper both accelerate tarnish, and the print can transfer.
Wool and felt are common in old flatware chests and cause the same problem, though a chest specifically lined with treated anti-tarnish fabric is designed to prevent it. Check what your chest is lined with before trusting it.
Also avoid storing silver near a dishwasher vent, a sink, or a stove, where humidity and cooking vapors are concentrated.
Should Silver Flatware Go in the Dishwasher?
It is better not to. Dishwasher detergent is strongly alkaline and can dull or pit silver, high heat accelerates tarnish, and silver touching stainless steel in the same wet load drives a reaction that marks the silver. If you do run it, use a low-heat setting, keep it away from stainless, and remove and dry it right away.
Hand washing with warm water and mild dish soap, followed by an immediate dry with a soft towel, is the safer routine. Water spots on flatware in general are covered in how to clean flatware with hard water spots.
Use It, Do Not Just Store It
Regular use genuinely slows tarnish, because handling and washing keep removing the earliest film before it darkens.
A silver set used monthly stays bright with almost no polishing. A set stored untouched for years needs a real polish before its next dinner.
If you polish, use a product made for silver, work with a soft cloth, and rinse and dry completely afterward. Never use an abrasive powder or a scouring pad, and be especially careful with silver plate.
Practical Storage Setups
A dedicated flatware chest lined with anti-tarnish fabric is the simplest complete answer, and it keeps pieces from scratching each other.
A drawer works if you add a tarnish-inhibiting drawer liner and the drawer is in a dry interior room. Individual anti-tarnish sleeves handle serving pieces that do not fit a chest.
Tarnish-absorbing strips added to a chest or drawer extend the interval further and are replaced periodically.
Keep silver separate from knives with carbon steel blades, which rust and can mark neighboring pieces. Wooden knife storage has its own maintenance, covered in how to clean a knife block and the narrow slots inside. And when the dining room cabinet and the surfaces around it need their own attention, scheduled house cleaning services handle those on their own schedule.
FAQ
What causes silver to tarnish?
Tarnish is silver sulfide, formed when silver reacts with sulfur compounds in the air. Humidity speeds it up, and materials like rubber, wool, felt, and newspaper release sulfur directly. Foods including eggs, onions, mustard, and salt attack silver on contact, with salt being the most damaging.
How do you store silver so it does not tarnish?
Wash and dry each piece completely, then wrap it in anti-tarnish cloth or acid-free tissue, or lay it in a chest lined with tarnish-inhibiting fabric. Keep it in a dry interior room rather than a basement or garage. The barrier plus low humidity is what slows the reaction.
Can you store silver in plastic bags?
Only if the silver is wrapped in anti-tarnish cloth or acid-free tissue first. Plastic against bare silver can trap moisture and some plastics off-gas, both of which make things worse. The wrapping is the actual barrier, and the bag simply limits airflow around it.
Why should you never use rubber bands on silver?
Rubber releases sulfur compounds continuously, and a band left on a bundle of silver leaves a permanent black stripe across every piece it touches, often within a few months. The marks can be so deep that polishing does not fully remove them. Use anti-tarnish cloth instead.
Can silver flatware go in the dishwasher?
It is better hand washed. Alkaline detergent can dull or pit silver, heat accelerates tarnish, and silver touching stainless steel in the same wet load drives a reaction that marks the silver. If you must, use a low-heat setting, isolate it from stainless, and dry it immediately.
Does using silver regularly keep it from tarnishing?
Yes. Regular use and washing keep removing the earliest film before it can darken, so a set used monthly stays bright with hardly any polishing. A set stored untouched for years builds a heavy layer that takes a real polishing session to remove.
How often should you polish silver flatware?
With good storage, once or twice a year is usually enough, and often less. Polishing removes a small amount of metal each time, which matters most on silver plate where the layer is thin. Store it well and polish only when the tarnish actually shows.
