A towel comes out of the dryer feeling stiff enough to stand up on its own, and a t shirt feels scratchy against the shoulders. That is not one problem with one fix. There are four or five separate causes, they produce slightly different results, and each one has its own answer.
What stiffness actually is
A soft towel is soft because thousands of individual loops move independently of each other. Your hand feels the movement, not the fibre.
Anything that coats those fibres, glues them to each other, or makes them brittle stops that movement, and the fabric reads as board rather than cloth.
Four things cause it. Mineral deposit from the water, detergent left in the fabric, a build up of softener, and fibre damage from heat.
A fifth cause is not damage at all. Air drying without any tumbling sets the fibres in whatever position they dried in, and there is nothing wrong with the fabric.
The causes stack, which is why people try one fix, get a small improvement, and conclude that nothing works.
So it is worth spending a minute working out which ones you have before changing anything.
Telling the causes apart
Each cause of feeling stiff leaves a slightly different signature, and the fabric tells you which one you have if you check it.
Stiff with a faintly chalky feel, whites drifting grey, and soap that never quite lathers in the shower. That is water hardness, and it is the most common cause by a wide margin.
Stiff but slightly slick or waxy, with a towel that pushes water around instead of absorbing it. That is softener build up.
Stiff with a faint detergent smell in the dry fabric is residue. Confirm it by running the load again with no detergent at all and watching the water. Suds in a plain rinse means there was too much in there.
Rough and thin rather than genuinely stiff, with more lint in the filter than usual and a fabric that looks slightly fuzzy and tired. That is heat damage, and it is the one you cannot undo.
Stiff only when air dried, and soft when tumbled, is the drying method rather than anything in the fabric.
Most households have two of these at once, usually hard water plus one other.
Mineral deposit from hard water
Hard water is the reason most loads end up feeling stiff, and it causes two separate problems in a wash because the dissolved calcium and magnesium do two different things.
First, they react with detergent and form an insoluble compound that settles into fabric and stays there. That deposit is the chalky film you can feel, and it accumulates wash after wash.
Second, they consume detergent. Part of every dose is spent binding minerals before any of it reaches the soil, so a normal dose behaves like an under dose.
The instinctive response is to pour more detergent, which makes the residue problem worse without fixing the hardness.
The direct fix is a builder. Half a cup of washing soda in the wash ties up the minerals, and the detergent then works at its normal dose.
Half a cup of white vinegar in the rinse helps dissolve deposit that is already in the fabric. Never put it in the same load as chlorine bleach.
Water volume is the other half of it. Mineral rich rinse water leaves mineral behind, so a generous rinse in a machine that fills properly removes far more than a stingy one.
Why too much detergent leaves a load feeling stiff
Dosing instructions assume a home sized load in reasonably soft water, and most people pour by eye anyway.
Surfactant that is not rinsed away stays in the fibre. It is slightly tacky, it attracts and holds soil, and it makes fabric feel rough and look dull.
Once residue is in the fabric it also traps odour, which is why an over dosed towel can smell faintly stale straight out of the dryer.
Overloading produces exactly the same outcome from a normal dose, because a packed drum cannot move enough water through the fabric to rinse it.
Cut the dose by about a third and see what happens over three or four washes. Almost nobody needs the full cap, and a load that stops feeling stiff after that change tells you the dose was the cause.
To clear what is already there, run the load again with no detergent and an extra rinse, and repeat until the water stays clear.
Cold washing makes this worse, since some detergents dissolve poorly at low temperature and undissolved product sits in the fabric rather than working in the water.
Softener, both none of it and too much
Fabric softener causes stiffness in two opposite ways, which is why the advice about it is so contradictory.
Using none of it in hard water means nothing at all is counteracting mineral deposit, so cotton dries hard, especially on a line.
Using it every load coats the fibre with a waxy film that builds up over months. Eventually that coating is thick enough that the fabric feels stiff and slick at the same time and stops absorbing water.
That second one is the reason softener should never go near towels, athletic wear or microfibre. Absorbency and breathability are the properties it destroys first.
To strip a build up, wash the items hot with no detergent, half a cup of washing soda and an extra rinse. It takes two runs on badly coated towels.
After that, use softener sparingly or not at all, and use wool dryer balls instead. They soften mechanically by keeping the load separated and tumbling.
If you keep using liquid softener, dilute it and use less than the cap suggests. The dose on the bottle is generous.
Over drying and heat damage
Cotton needs a small amount of residual moisture to stay supple, and a dryer run past the point of dry takes that out and then keeps going.
Fibres that dry out completely become brittle. Brittle cotton feels rough rather than soft, and it breaks, which is what lint actually is.
That is the difference between lint and dust. The lint filter is collecting your towels, a little at a time, and a load that is over dried repeatedly gets thinner as well as rougher.
This damage is permanent. Nothing puts broken fibre back, which is why it is the one cause on the list where prevention is the only option.
Use a moisture sensing cycle rather than a timer, and use medium heat rather than high.
Take the load out while it still feels very slightly cool and damp at the seams, and let it finish on a rack or a hanger for twenty minutes.
Under filling the dryer causes over drying as much as anything else does, because a small load reaches dry long before the cycle decides it has.
Line drying, and the fix for it
Air drying leaves cotton feeling stiff for a mechanical reason rather than a chemical one, and in this case nothing is actually wrong with the fabric.
In a dryer, fabric is tumbled constantly while it dries, so the fibres are flexed and separated as the water leaves them.
On a line in still air, nothing moves. Water evaporates, the fibres set exactly as they are lying, and any mineral in the water crystallises in place between them.
That is why line dried towels are the worst case and line dried shirts are barely affected. Pile fabric has the most to lose.
Shake each item out hard before hanging it, and shake it again when you take it down. It makes a real difference and it costs nothing.
Ten minutes in a dryer on low after the load comes off the line gives you the airing and the softness at the same time.
Do not leave things on the line past dry. Over drying in air is still over drying, and in dry moving air it happens quickly.
The Chandler part
Mineral rich supply is the default assumption here, and it is the reason most local complaints about towels feeling stiff never resolve. People change detergent brands repeatedly while the actual cause sits in the water.
Try the builder before you try anything else. Half a cup of washing soda in the wash and a reduced detergent dose will do more in three loads than a year of switching products.
Desert air makes outdoor drying very fast, which is a real advantage and the reason so many loads here are dried outside. It also means a load reaches dry and then keeps drying while nobody is watching, and that is where the harshness comes from.
So bring things in as soon as they are dry rather than at the end of the afternoon, and give everything a hard shake going out and coming back in. A breeze does much of that work for you and still air does none of it.
Dust is the last piece. Fine airborne grit works into fabric and adds a gritty edge that people read as harshness, and it responds to generous water volume rather than to any change in product.
The same logic applies to the dryer indoors. Air that starts out very dry pulls the last moisture out of a load quickly, so a timed cycle set by habit is usually running several minutes longer than it needs to.
Where the rinse actually finishes
Every cause on this list except heat damage comes down to what stays in the fabric after the last rinse.
The machines at our self-service laundry on North Arizona Avenue carry the water volume that a large drum needs to move mineral and detergent out of a full load instead of leaving both of them behind in the fibres.
Our machines and the store are cleaned daily.
Our wash-dry-fold service covers the everyday laundry.

The short version
Laundry feeling stiff has four or five causes and they stack. Chalky and dull with poor lather is hard water, so add half a cup of washing soda and cut the detergent dose. A faint detergent smell or suds on a plain rerun is residue, so cut the dose by a third and add a rinse. Slick and non absorbent is softener build up, stripped with a hot wash, washing soda and no detergent. Rough, thin and linting is heat damage and it is permanent, so dry on medium and pull the load out slightly damp. Board hard only after air drying is mechanical, fixed by shaking hard and ten minutes of low tumbling.
