Towels are the heaviest, thirstiest and lintiest thing in a household wash, and they are the item most often thrown in with everything else. Washing towels well is mostly about giving them space, water and heat, and about leaving out the two products people add to make them feel softer.
Why washing towels is a different job
A towel is built to do the opposite of what a shirt does. A shirt is meant to shed water. A towel is meant to hold it.
That difference is structural. Terry cloth is a pile of thousands of raised cotton loops, and the loops are the entire mechanism, since they create the surface area water moves into.
So everything that goes wrong with a towel is something happening to those loops. They get coated, they get crushed, or they get filled with residue.
Absorbency is the third. Towels soak up wash water and hold it inside the pile, so a load of them needs more water than the same volume of clothing does.
They shed as well, releasing cotton fibre continuously and heavily when new. Put those properties together and towels stop looking like clothes in a different shape.
Lint and where it ends up
Lint from a towel does not stay on the towel.
In the wash it goes into the water and settles onto whatever else is in the drum, and it settles worst on dark fabric and on anything with a smooth face.
Fleece, corduroy and knitwear pick it up and hold it, and no amount of shaking gets it back out once the load has been through heat.
New towels are the worst offenders by a distance. The first three or four washes shed hard as loose fibre from manufacturing works free.
The dryer is where the remainder goes. A towel load fills a lint screen in a single cycle, and a full screen is the most common reason a dryer takes twice as long as it should.
Clean the screen before the load rather than after it, since you have no idea what the previous load left behind.
The simple answer is washing towels together and nothing else. A towel load sheds onto other towels, and that does not matter to anybody.
Softener, residue and losing absorbency
The most common complaint about washing towels is that they stop drying anything, and the cause is nearly always something added on purpose.
Fabric softener works by depositing a thin waxy layer onto fibre. That layer is what makes fabric feel smooth under a hand.
On a towel it fills and coats the loops. Water then meets a water repellent film instead of cotton, and the towel pushes moisture around instead of taking it in.
The effect builds. A handful of washes with softener and a towel feels lovely and dries nothing.
Dryer sheets do the same thing by a different route, transferring the coating during the heat cycle instead of during the wash.
Detergent is the other half of it. Too much detergent in a towel load will not rinse out, because towels hold water and hold whatever is dissolved in it.
Residue sitting in the loops stiffens them, dulls the colour, and gives a towel that flat stale note it picks up when it is even slightly damp.
Use about half what the volume suggests, and add a rinse if the machine offers one.
To recover a towel that has already gone waxy, run it hot with no detergent and a cup of white vinegar, then run it again with half a cup of baking soda and nothing else. Two empty cycles undo months of build up.
Towels need room to move
Washing towels fails by compression more often than by anything else.
Wet towels swell and pack. A drum that looked sensibly loaded while dry becomes a solid mass once the water goes in.
A packed drum cannot tumble, and without tumbling there is no mechanical action, which leaves the detergent working alone.
Rinsing suffers worse than washing does. Fresh water cannot push through a compressed mass, so soapy water stays sitting in the middle of the load.
Then the spin fails as well. An unbalanced packed drum spins slower, and a slower spin means wetter towels going into a dryer that is already the slow part of the trip.
Load a towel drum to about two thirds full while dry, not to the top. The wet towels will claim the rest.
This is where a large drum earns its place. Towels are the one load where machine size is doing real work rather than only saving a trip.
Why a damp towel goes sour first
Towels pick up that sour note before any other laundry does, and the reason is simply that they spend their working lives wet.
A used towel goes onto a hook or into a hamper holding water in the pile. A shirt does not.
Folded or bunched, a damp towel keeps that moisture pressed against itself for hours, and the smell develops inside the fold rather than on the surface.
The same thing happens in a machine. A finished wash left sitting in a closed drum turns faster with towels than with anything else in the house.
It happens at the end of a poor rinse as well, because residue holds moisture down in the loops long after the towel feels dry to a hand.
The smell is not on the surface, which is why a quick rewash usually does not shift it. It is down in the pile, and removing it takes hot water, a real rinse and a full dry.
Prevention is entirely about never leaving a towel damp. Hang them spread out rather than folded, move a finished wash into a dryer straight away, and put nothing away that is not completely dry.
Drying fully rather than nearly
Nearly dry is the state most towel problems come out of.
A towel carries a lot of mass in the middle of its pile, and the outer surface dries well before the core of the loops does.
So a towel that feels dry, folded and stacked immediately, is often still holding enough moisture to go stale in the cupboard inside a week.
Give a towel load more time than seems necessary, and check the thick hems, which are the last parts to finish.
High heat is fine for cotton and this is the one load where heat is genuinely doing useful work, since it drives moisture out of the depth of the pile rather than off the face of it.
Dryer balls keep the load moving and stop towels wrapping around each other. Take them out promptly and shake each one before folding. A towel stacked straight from a hot drum without a shake traps the last of its moisture between the folds.
Why a batch of towels wants its own cycle
Everything above points one way, which is that washing towels works best in a load of nothing but towels.
The lint reason is the obvious one. Towels shed and clothes collect.
The water reason is bigger. Towels want a high water level, a long wash and a hard spin, and most clothing wants less of all three.
Heat is a third. A cotton towel load takes a hot wash and a hot dry comfortably, and the shirts and synthetics in a mixed load do not.
Timing is the fourth and it is the one people actually notice. Towels dry far slower than clothes, so a mixed load leaves either the clothes over dried or the towels damp.
A household washing towels weekly usually has enough of them to fill a large drum on their own, which happens to be exactly the right amount.
Bath towels, hand towels, bath mats and kitchen cloths can all run together, with one caution. Bath mats with a rubber backing want a warm wash and a low dry, because heat cracks the backing and the pieces end up spread through everything.
The Mesa part
Two conditions here work in a towel’s favour and one works steadily against it.
Dry air is the ally. Moisture leaves fabric quickly in this climate, so a bath towel spread across a rail is genuinely dry again by morning, and a towel that dries between uses never starts down that road at all. The benefit disappears the moment a towel is left bunched on a hook, because the outside dries and the inner fold does not.
Summer heat pushes the other way. A wet towel left in a closed bag or in a car through a hot afternoon turns strong in hours rather than days, and warmth is what accelerates it. If a gym towel or a pool towel is going to sit before wash day, it wants to sit spread out with air moving over it, never rolled up.
Mineral rich water is the factor working against every towel in the region. Calcium and magnesium bind with detergent and deposit into the pile, and that deposit is exactly why towels here feel crunchy after a year even when nothing else about the routine has changed. Washing towels here calls for a smaller dose, an extra rinse, and an occasional strip wash with vinegar and baking soda.
Blowing grit is the last one. Fine dust settles into terry readily, because a raised loop is an ideal place for a particle to lodge, and grit sitting in a pile grinds against the cotton every time the towel is used. Shaking towels out before they go into a machine removes a surprising amount of it, and a full water volume carries the rest away instead of redepositing it.
Where a full batch of towels fits
Towels need water and room more than they need technique, and that is a machine question.
The machines at our self-service laundry on East Broadway Road take a household’s whole towel batch at once, with the water volume terry needs to rinse clean and the drum size that keeps a heavy wet load tumbling instead of packing solid.
Our machines and the store are cleaned daily.
Nou wash-dry-fold service covers the everyday laundry.
For general guidance, The American Cleaning Institute publishes a fabric care guide that is a useful cross-check.
The short version
Washing towels is a job for its own cycle. They shed lint onto everything else, they want more water, more heat and a harder spin than clothes do, and they dry far slower than anything they might be mixed with. Skip fabric softener and dryer sheets, which coat the loops and cost a towel its absorbency, and use about half the detergent you would expect, since residue in the pile stiffens it and holds damp. Load a drum around two thirds full while dry so wet towels still have room to tumble and rinse. Then dry fully rather than nearly, check the hems, and shake each one out before folding.
