The flannel wrap that came with a set of silver looks like nothing in particular. It is soft, slightly fuzzy, usually a dull blue or gray, and after a few years of sitting in a drawer it looks grubby enough that washing it seems like the obvious thing to do. It comes out of the wash clean, soft and completely useless. The cloth was never just a cloth. What made it work was a chemical treatment carried in the fiber, and water takes that treatment out while leaving the flannel behind looking better than ever.
What Tarnish Actually Is
Tarnish on silver is not dirt sitting on the metal. It is the metal itself, chemically changed. Silver reacts with sulfur compounds to form silver sulfide, a dark compound that grows as a thin layer on the surface, and the silver in that layer has stopped being silver. Polish a tarnished spoon and you are removing part of the spoon along with the discoloration.
The sulfur comes from the air and from the things silver touches. Trace hydrogen sulfide and carbonyl sulfide are present in ordinary air almost everywhere. Wool and felt contain sulfur in their protein structure. So do rubber bands, some papers and cardboards, eggs, onions and mustard. Any of them will darken silver that sits against them.
The color changes as the layer thickens. A very thin film of silver sulfide looks pale yellow, then warm brown, then takes on iridescent purples and blues as it interferes with light, and finally reads as flat black. That progression is a reliable guide to how long the reaction has been running. A piece that has only gone faintly yellow has been exposed for a short time.
Because the surface is converted rather than coated, wiping does nothing at all. Removing tarnish means either abrading the sulfide layer off, which takes a little silver with it, or chemically reducing it back to metal. Both are repairs, which is why preventing it is worth far more than correcting it.
How the Treated Cloth Works
The base is usually cotton flannel or a soft woven cotton, chosen because it is non abrasive and will not scratch a polished surface. That part is just cloth. The function comes from what has been added to the fiber, and the cloth is essentially a carrier for it. An untreated flannel of the same weight is simply a soft wrap that keeps dust off.
The treatment is a sulfur scavenger. Depending on the maker it may be a finely divided silver salt, or a compound of zinc or copper, or activated carbon, and in each case the principle is the same. The chemistry in the cloth reacts with or adsorbs sulfur gases more readily than your silver does.
That makes it a sacrificial material. Sulfur arriving in the air around a wrapped piece meets the cloth first and is captured there, so it never reaches the metal. The silver stays bright not because anything has been applied to it, but because something else took the hit on its behalf.
This is why proximity and enclosure matter so much. The cloth protects the air immediately around it and little else, which is why these come as wraps, bags and drawer liners rather than as sheets to lay nearby. In a sealed box with the pieces wrapped, the treatment has a small volume of air to manage and manages it well.
Why Washing Destroys It
The treatment is held in the fiber rather than bonded to it. It was applied as a solution or a dispersion and left to dry in place, which means it is sitting among the fibers in a form that water can take up again. There is no chemical anchor holding it to the cotton. That is a deliberate choice by the maker, because an active material locked tightly into the fiber could not react freely with anything in the air.
A wash removes it with great efficiency. Water dissolves or suspends the active material, detergent builders chelate metal compounds specifically well, agitation flushes them out of the yarn, and the rinse carries everything away. What comes out of the machine is clean flannel, and clean flannel does nothing for silver.
Nothing about the washed cloth looks different, and that is the trap. It still feels soft, it is still the same color, and it still gets wrapped around the serving pieces with the same confidence. The silver then darkens on schedule and the cloth gets blamed for being a gimmick.
There is a second reason washing is pointless even if it did no harm. The treatment is consumed as it works, since each molecule of sulfur captured uses up some of the capacity. A cloth that has been in service for years is partly spent already, and no amount of laundering renews it. Replacement is the only route.
Discoloration Is the Cloth Doing Its Job
A treated wrap that has gone patchy, gray or brown is not dirty in the ordinary sense. It is carrying sulfur compounds that would otherwise be on the metal, and the discoloration is the visible record of that. Judging the cloth by appearance leads directly to the mistake of washing it.
Useful information is in those marks. Heavy discoloration on one face often means that side was exposed to more air, or pressed against something releasing sulfur, such as a wool lining, a rubber band or a cardboard divider. Those are worth removing from the storage box.
Handling is still worth some care. Shake out crumbs and loose grit outdoors rather than brushing hard, since grit trapped against silver is exactly what puts fine scratches in a polished surface. Keep the cloth dry, because damp cloth against metal accelerates every reaction involved. A wrap kept in a dry, sealed box lasts considerably longer than one left loose in an open drawer.
When the cloth stops working, it is finished. There is no way to test remaining capacity at home, so the practical signal is simply that pieces stored with it are tarnishing again as fast as unprotected ones. At that point an anti tarnish cloth has done what it was built to do and should be replaced.
How a Polishing Cloth Differs
A polishing cloth looks similar and does the opposite job. It is impregnated with a mild abrasive, typically precipitated chalk or a fine iron oxide rouge, often with a little soap and sometimes a tarnish inhibitor mixed in. Its purpose is removal, by rubbing the sulfide layer off the surface.
That means the two cloths are not interchangeable in either direction. A treated storage wrap has no abrasive in it and will not clean anything. A polishing cloth contains abrasive, so wrapping silver in it for storage means leaving fine cutting particles pressed against a polished surface for months.
A polishing cloth also goes black with use, and that is correct. The black is silver sulfide and a trace of silver coming off the piece and into the cloth. People wash them for exactly the same reason they wash the other kind, and the result is the same, a clean cloth with none of its working material left.
The simplest way to keep it straight is by job. One prevents and lives in the box, one removes and lives in a drawer with the cleaning supplies. Neither goes in a washing machine, and neither is improved by anything except being used and then replaced when it is spent. Confusing the two is the common error, and it costs you either a darkened piece or a scratched one.
Storing Silver in Dry Phoenix Air
Phoenix households have an advantage with silver that cooler, damper places do not. The reaction between silver and sulfur runs faster when there is moisture present, so very dry indoor air genuinely slows tarnishing. Pieces stored in a dry closet here often look better after a year than the same pieces would elsewhere.
That advantage disappears in an open drawer. Dry air still carries sulfur, and air exchange is what brings a fresh supply, so an unsealed drawer keeps supplying more of it. Sulfur does not need humidity in order to arrive, only in order to react quickly. A sealed box with a treated wrap inside beats a dry room every time, because it limits how much air is involved at all.
WaveMAX Phoenix is at 1615 W Camelback Rd, STE 101. The treated wraps stay out of the machines there, but the table linen that comes out alongside the silver does not, and napkins, runners and a long cloth are all ordinary washable cotton and linen.
The Linen That Goes With It
Silver tends to come out of storage at the same time as the good table linen, and the linen is the part that genuinely belongs in a machine. A long cloth that has been folded in a box for most of a year carries creases, dust from the fold lines and often a mark or two from the last gathering.
The machines at our self-service laundry on West Camelback Road take a full length table cloth and a set of napkins without cramming them, which matters for stored linen, since a long cloth needs room to open out in the water if the fold creases are going to relax at all.
Our machines and the store are cleaned daily.
Our wash-dry-fold service covers the everyday laundry.

The short version
Tarnish is silver converted to silver sulfide by sulfur in the air, not dirt on the surface. A treated storage cloth works by catching that sulfur first, using a scavenger compound held in the fiber. Washing dissolves the treatment out and leaves ordinary flannel, and the treatment is consumed in use anyway, so a spent cloth gets replaced rather than cleaned. A polishing cloth is a different product with abrasive in it, and it should not be washed either.
