The boxes come down, the good cloth comes out, and there is a yellow rectangle across one corner of a tablecloth with edges as straight as a ruler. Nothing in a closet makes a straight line except something that was lying underneath it. The liner put down to keep the wood off the linen has been doing something of its own for the last eleven months, and what it did depends entirely on what it is made of. Some are inert and genuinely useful. Some are slowly putting their own ingredients into whatever is pressed against them.
What a Liner Is Supposed to Prevent
Bare wood is not a neutral surface. Wood gives off organic acids as it ages, chiefly acetic and formic acid released out of its own structure, and in an enclosed drawer those vapors have nowhere to go. Oak is the worst of the common woods for it, and the effect does not fade as the piece gets older.
Manufactured board adds more again. Particleboard and medium density fiberboard are held together with urea formaldehyde adhesives that release formaldehyde slowly, which in the presence of water becomes formic acid. A drawer made of board is therefore a small acidic enclosure whether anything has ever been spilled in it or not.
Acid matters to cellulose because it cuts the chains. Acid hydrolysis breaks the long cellulose molecules of cotton and linen into shorter ones, and shorter chains mean a weaker fiber. The visible result is yellowing first and brittleness later, and the brittleness announces itself as a cloth that tears along a fold instead of creasing.
There are secondary effects too. Acidic vapor tarnishes metal, so hooks, snaps and any metallic thread go dark, and that tarnish can transfer a gray mark to the cloth beside it. A barrier between wood and textile is a genuinely sound idea. The only question is what the barrier itself is doing while it sits there.
Vinyl, Plasticizer and the Greasy Shadow
The adhesive backed rolls sold for shelves are usually plasticized polyvinyl chloride. On its own PVC is a hard rigid plastic, so a liquid plasticizer is blended in to make the film flexible, typically a phthalate or an adipate ester. That plasticizer is not chemically bonded to the polymer at all. It is simply dissolved in it.
Anything merely dissolved will eventually migrate. The plasticizer travels slowly to the surface of the film and from there into whatever is touching it, and cotton in contact for a year is in contact for a very long time. What arrives in the cloth is an oily liquid, and in the yarn it behaves exactly like any other oil.
So the mark it leaves is a grease mark. It looks translucent rather than colored, it has no sharp boundary inside the contact area, and it darkens the cloth wherever the air gaps in the yarn have been filled in. People look for a stain and find a shadow, which is why the cause so often goes unidentified.
PVC has a second habit as well. It breaks down slowly and gives off hydrogen chloride as it does, which in a closed drawer means an acidic atmosphere sitting right against the cloth. The liner put in to protect linen from the acidity of the wood turns out to be a better source of acid than the wood was.
Paper, Acid and the Brown Line
Ordinary paper is not neutral either. Wood pulp paper contains lignin, and most of it was sized with alum and rosin, which leaves it mildly acidic from the day it was made. Put acidic paper against cotton for a season and the acid migrates into the cotton along the line of contact between them.
That is where the hard brown edge comes from. A sheet laid under a stack transfers acid most strongly where cloth and paper touch directly, so the mark follows the outline of the sheet and the fold lines of the cloth. Conservators call it acid migration, and it is the reason they reach for unbuffered acid free tissue instead.
The buffering question is worth knowing, because the right answer differs by fiber. Acid free tissue is sold both plain and buffered with an alkaline reserve, and for cotton and linen the buffered kind helps, since it neutralizes incoming acid. For wool and silk it does not. Protein fiber is damaged by alkali and prefers slightly acidic conditions.
Newspaper is the clearest bad case and it is still in use. Along with being acidic it carries printing ink, which is oil and pigment together and transfers to cloth under pressure, particularly where the air is humid. A newspaper lined drawer hands a textile acid, oil and pigment in one tidy arrangement.
Scented and Cedar Liners Leave Oil
Cedar works by giving off aromatic compounds, principally cedrol and thujopsene, which are volatile oils. Volatile means that they leave the wood. It does not mean that they disappear. They condense onto the nearest cool surface available, and inside a closed drawer the nearest cool surface is the cloth.
Deposited oil then does what deposited oil does. Over months it oxidizes into a heavier, yellower residue that is no longer volatile and no longer smells of much, and it sits in the fiber as a faint translucent cast across the whole contact area. Cedar lined storage has a particular yellow note that comes from precisely this.
Scented drawer papers work the same way with a different payload. The fragrance is carried in a light oil, and that oil transfers to cloth on contact and then ages exactly as the cedar compounds do. The smell that will not wash out of a stored sheet is usually not a smell at all. It is an oil residue with a smell attached to it.
Getting it out is an oil problem rather than a perfume problem, and that changes the approach. Warm water within whatever the care label permits, with a detergent carrying surfactant and ideally lipase, is the route that works. Repeated cold washes with extra softener are what people try, and softener adds oil to an oil problem.
Pressure, Edges and Printed Texture
The waffle textured grip liners are a separate case mechanically. They are usually a foamed PVC or an EVA, both plasticized, and the surface is an open grid of ridges. Under the weight of a stack those ridges press into cloth and the pattern transfers as a lasting texture in the fiber, which shows worst on linen.
Pressure drives everything else as well. The bottom of a stack carries the most load, which means the closest contact and the fastest transfer of whatever the liner has to give, so the piece reached for last is the one with the mark on it. Rotating a stack between seasons is a small habit that does a lot.
Edges concentrate the problem again. The cut edge of an adhesive drawer liner leaves adhesive exposed, and adhesive is tackier and more mobile than the film it is attached to, so the sharpest marks line up with the edges of the sheet rather than its middle. Overlapping seams between two pieces do the same thing.
What comes out and what stays follows the chemistry. Plasticizer and fragrance oil are oils, and they will mostly wash out of cotton in warm water, leaving at worst a faint cast behind. Acid damage and ink will not, because one is a change in the fiber itself and the other is pigment. Unfinished cotton or plain acid free tissue does the job without contributing anything.
Stored Linens and Closets in Temple
Temple gets long hot stretches, and heat is the accelerator in all of this. Plasticizer migrates faster at higher temperatures, cedar oils come out of the wood faster, and the acid hydrolysis of cellulose speeds up steadily as well. A closet against a warm exterior wall is a harder place to store cloth than the middle of the house.
Swings in humidity matter too. Cloth takes up water from the air and gives it back again, and every swing moves water through the fiber, which is the vehicle that carries dissolved acid and migrated oil deeper in. A liner’s contribution is not one event but a slow process repeated with every change in the air.
This is the stretch of the year when all of it becomes visible. Pieces that have been lying on a liner since the last round of gatherings come out to be used, and the marks get found in good light on a table rather than in a drawer. A wash before they go back, rather than only after they come out, breaks the cycle.
Before It Goes Back in the Drawer
Anything coming out of long storage with a translucent cast across it is carrying oil, and oil wants warm water and room to move rather than a stronger product. A full tablecloth also wants a drum it can open out inside, because water cannot reach a contact mark that is folded hard against itself.
The machines at our self-service laundry on South 31st Street give a tablecloth or a stack of napkins warm water with enough volume to carry migrated oil clear of the weave, and the larger drums let a big piece unfold rather than ride a whole cycle creased over the mark.
Our machines and the store are cleaned daily.

The short version
A liner is worth having, because bare wood and particleboard give off acids that yellow and weaken cotton. The problem is what some of them give off in return. A vinyl drawer liner releases plasticizer, which arrives in the cloth as an oily translucent shadow, and acidic paper transfers a hard brown line at the contact edge. Cedar and scented papers leave an oil that ages yellow. Unfinished cotton or acid free tissue does the work without adding anything.
