There is a particular kind of stiffness a baking cloth gets. Not crumpled, not soiled exactly, but set hard in patches, like thin cardboard, with a pale crust along the fold lines. A kitchen towel put through the same work never does this. The difference is what was on the cloth and what happened to it afterward. Flour and water, pressed into a tight weave and then left to dry, make something closer to a glue than a soil. It is worth knowing which part of that is protein, which part is starch and which part is fat, because the three want opposite things from the water.
Why The Weave Is So Tight
A proper rolling cloth is heavy cotton canvas or duck, woven plain and woven dense. That is deliberate. A dense surface holds a layer of flour on top of itself without letting the flour fall through, and it stops a soft dough from pressing into the structure and sticking. The cloth works because the dough never reaches the fiber.
The same density works against you in the sink. Water moves through cloth by capillary action, through the spaces between the yarns, and a tight weave has very few spaces. Detergent solution soaks in slowly and leaves slowly. A heavy canvas can be wet on both faces and still almost dry in the middle of its own thickness.
That matters because anything which gets into the weave is then difficult to flush back out. A loose kitchen towel rinses almost by itself. A canvas cloth holds whatever has entered it, and the only way through is time in the water plus enough mechanical flexing to pump water in and out of the structure.
So two things are true at once. The tight weave is why the cloth is good at its job, and the tight weave is why it is hard to clean. Any approach that works has to account for both, which mostly means being patient with the rinsing rather than aggressive with the washing.
One more consequence of the weave is worth planning around. Canvas comes out of a wash heavy with water and it rubs hard against lighter cloth, so a rolling cloth is better run with towels or on its own than mixed in with shirts or table linens that have nothing like the same weight.
Flour, Water And Pressure Make Glue
Wheat flour is mostly starch with a modest amount of protein. The two proteins that matter, glutenin and gliadin, do nothing much while they are dry. Add water and they hydrate. Add mechanical work, which is what rolling is, and they link together into a continuous elastic network. That network is gluten, and it is the whole point of the exercise in the bowl.
It is also what happens in the cloth. Loose flour draws moisture out of the dough and from your hands, pressure from the pin presses the damp mixture down into whatever gaps the weave offers, and the rolling motion works it in much the same way it works a dough. A thin gluten film forms in and around the yarns.
Then it dries. A gluten film dries into a hard, slightly glossy skin, and the starch granules trapped in it dry alongside into a rigid filler. The result is a composite sitting inside the weave, gripping individual fibers, and it is stiff for the same reason a dried paper paste is stiff.
This is why the stiffness comes in patches and why it follows the pin. It maps the places where pressure was highest. It is also why a cloth stiffens more each time if it is only shaken out between uses, because every session adds another layer onto a surface that already has one.
Why Hot Water Sets It Instead
Both components of that paste react badly to heat in water, and they do it at temperatures a hot tap reaches easily. Protein is the simpler case. Heat unfolds a protein chain, and unfolded chains bond to each other, which is coagulation. Once a protein has coagulated it is no longer soluble in water at all.
An egg on a pan is the everyday demonstration. Raw egg wipes off with cold water. Cooked egg does not, and no amount of washing turns it back into raw egg. Gluten in a cloth does the same thing on a smaller scale. A hot wash takes a soft protein film that water could still have softened and converts it into a set one.
Starch does something different and just as unhelpful. Heated in water, starch granules absorb water and swell until they burst, releasing long molecules that tangle into a gel. That is gelatinization, and it is how a sauce thickens. In a cloth the gel forms around the fibers and then, as it cools and dries, it hardens into a film tougher than what you started with.
Put those together and a hot first wash is the worst move available. It cooks the protein and gelatinizes the starch in the same cycle, and everything after that is working against a set film rather than a dried paste. The stiffness people describe as permanent is usually this and nothing else.
A Cold Rinse Does The Work
Cold water is the right first step and the reason is specific. Cold water hydrates a dried starch and protein paste and softens it without triggering either reaction. The film swells, loses its grip on the fiber and begins to break up, and none of it coagulates or gelatinizes while the water stays cool.
Give it time and movement. Run cold water through the cloth, then flex and rub the stiff areas under the water so the weave pumps clean water in and loosened paste out. On a canvas this is the part that cannot be rushed, because the water has to physically travel through a dense structure in both directions.
A cold soak does the same job while you get on with something else. The paste keeps softening for as long as it stays wet, and a dried film that has been sitting in cold water comes away under very little pressure. Change the water once if it goes cloudy, because cloudy water is suspended starch looking for somewhere to settle.
Only then is detergent worth adding, and warm rather than hot. Most laundry detergents contain enzymes, amylase for starch and protease for protein, and those enzymes work by cutting long chains into short soluble pieces. They do that best in warm water, and they are useless against a film that has already been cooked solid.
The Fat Is A Separate Problem
A rolling cloth rarely carries flour alone. Butter or shortening comes out of the dough, and fat behaves nothing like starch. It is not water soluble at any temperature, it does not coagulate, and cold water does absolutely nothing to it. The pale translucent patches on a well used pastry cloth are fat rather than flour.
Fat needs the opposite conditions from the paste: warmth to keep it liquid, and a surfactant to surround it and hold it in suspension until the rinse. Detergent worked straight into the patch, then a warm wash, is the whole treatment. Rubbing without detergent achieves nothing, because there is nothing there for the water to hold on to.
Which is why the order matters so much on this one cloth. Cold rinse first, to get the starch and the protein out while they are still removable. Detergent and a warm wash second, to deal with the fat. Doing it the other way round sets the paste in the first minute and leaves you with both problems at once.
Last, do not dry a cloth that is still stiff and do not fold a stiff cloth away. Dryer heat oxidizes leftover fat into something detergent cannot lift, and a hardened film cracks along a fold and abrades the fibers around it. A cloth that comes out limp and even has been cleaned. A cloth that comes out crisp has not.
Pastry Cloth Care In Oklahoma City
Oklahoma City kitchens get a long run of baking at this time of year, and the cloth usually gets a long run with them. It comes out, gets floured, gets shaken off and goes back on the counter for the next round. Several sessions stack up before it is washed, and each layer of paste dries onto the one below it.
Dry air in this part of the country speeds up the drying step, and drying is the step that hardens the film. A damp cloth left on a counter in dry air can go board stiff in an hour or two. If the cloth has to sit before it can be washed, it is better off genuinely wet in cold water than drying out on the counter.
Heavy canvas is also awkward in a small home machine, because it holds a lot of water and it needs room to flex. WaveMAX Oklahoma City, at 6125 South May Avenue, has large drums and a choice of water temperatures, which is exactly what dense cotton needs: a cold cycle first, then a warm one with detergent.
Cold Rinse, Then Warm Wash
Dense cotton needs two different temperatures in the right order, and that is easier with machines you can set yourself. A cold cycle with plenty of water loosens the paste, and a warm cycle with detergent after it takes out the fat. A large drum also lets heavy canvas flex instead of sitting in a wet lump.
The machines at our self-service laundry on South May Avenue let you run a cold cycle first and a warm one after, which is the order a dense baking cloth needs, and the larger drums give heavy canvas enough room to flex so water can move right through the weave.
Our machines and the store are cleaned daily.

The short version
Flour, water and the pressure of a rolling pin make a gluten and starch paste that dries hard inside a tight weave. Hot water cooks that paste rather than removing it, because protein coagulates and starch gelatinizes at temperatures a hot tap reaches. Rinse cold first, with time and flexing, then wash warm with detergent for the fat. A cloth that comes out stiff has been set rather than cleaned.
