Laundry in deep winter is a different job from laundry in June, and the reason is not the cold itself. It is what below zero air does to the inside of a heated building. The air goes very dry, and dry air is behind the static, the stiff towels, the endless drying times and most of the rest of it.
Why below zero air makes a house so dry
Cold air holds very little water. That is a physical limit rather than a matter of weather.
When outdoor air at below zero temperatures comes inside and gets heated, the small amount of moisture it carries is spread through much warmer air, and the relative humidity collapses.
Indoor humidity in a heated house during a hard cold spell can fall into single figures, which is drier than a lot of deserts.
That number is doing more to your laundry than anything on the detergent label.
It also explains why the same washing routine that worked in September suddenly produces stiff towels and shocking doorknobs in January.
Static and what actually causes it
Static is a dryness problem rather than a detergent problem, which is why changing detergent rarely fixes it.
Friction moves electrons between materials. In humid air a thin film of moisture on every surface lets that charge bleed away continuously. In very dry air there is nothing to carry it off, so it builds up instead.
Synthetics are the worst offenders because they insulate and hold no moisture at all. Cotton and wool hold a little and cling far less.
A dryer load mixing cotton with synthetics is the worst combination, since the two sit at opposite ends of the charge scale and rub against each other for an hour.
The fixes that actually work all come down to not overdrying. Pull a load while it is still barely cool to the touch instead of running it until everything is bone dry.
Separating synthetics from cotton helps for the same reason, and wool dryer balls help by keeping the load open so it dries evenly and finishes sooner.
Why fabric feels stiff in winter
Two different things get described as stiff and they have different causes and different fixes.
Overdrying is the first. Fibres dried past the point of holding any moisture become brittle, and the cloth feels harsh rather than soft. Cotton towels show it first and worst.
Detergent and mineral residue is the second. It accumulates in fabric over months, and dry indoor air makes it far more obvious because there is no ambient moisture softening the feel of the cloth.
The test is simple. Run a load with no detergent at all. If it comes out noticeably softer, you have been overdosing and the residue is the problem.
Cold cloth also just feels different. Anything carried in from a cold car is stiff until it warms up, and that one is temporary and means nothing.
Fabric softener is not the answer to either. It coats fibres, and coated towels absorb less, which is the opposite of what a towel is for.
Damp laundry and the walk to the car
This is the genuinely practical winter problem and it is worth being blunt about.
Damp fabric in below zero air freezes, and frozen fabric is rigid rather than flexible. Folding or bending it at a crease stresses the fibres at that fold.
Anything with elastic, a coating or a printed design is the most vulnerable, because those materials go brittle in severe cold.
So the rule is to leave with laundry properly dry rather than nearly dry, and to carry it in closed bags rather than an open basket.
A car that has been parked is not a warm space. Laundry left sitting in a cold vehicle arrives home cold and slightly damp in the thick seams, which is exactly the state that turns musty in a cupboard.
Unpack and spread things out when you get in rather than putting a cold bag straight into a closet.
Winter layers take far longer to dry
Winter clothing in below zero weather is a different drying job from summer clothing, and the gap is wider than it looks.
A quilted or insulated coat holds water through its entire thickness, and insulation is designed to trap air, which means it traps moisture just as effectively.
Down is the extreme case. Wet down clumps, and it has to be broken up and dried right through or it stays matted and loses its loft for good.
Heavy sweaters, fleece linings, snow trousers and boot liners all hold several times the water that a shirt does.
These are the items where drying goes from forty minutes to a couple of hours, and where a small dryer usually gives up before the job is done.
Drying them alongside ordinary clothing is the worst arrangement, because the light items get baked dry while the heavy one catches up, which brings the static straight back.
Drying indoors and what it does to the room
Hanging laundry on a rack indoors is common through a below zero winter and it has a consequence people underestimate.
Every drop of water that leaves the fabric goes into the room. A single load can still hold a gallon or more of water after the spin, and all of it ends up in the air of the house.
In a very dry heated house some of that is welcome, since indoor humidity is otherwise extremely low.
Past a point it stops being welcome. Moisture that cannot escape condenses on the coldest surfaces available, which in a hard cold spell means window glass and the frames around it, and repeated condensation there damages finishes and grows mould.
The practical version is to dry indoors in a room with some air movement rather than a closed bedroom, and to watch the windows. Water running down the glass means the room has taken all it can.
Heavy items are poor candidates for a rack for exactly this reason. They release the most water over the longest time, and they stay damp long enough to smell.
Road salt on hems and cuffs
A below zero winter puts a specific kind of soil in a specific place, which is the bottom few inches of everything you own.
Salt splash dries into a pale ring on hems, cuffs and boot tops. The ring is mineral, so detergent does very little to it, and the answer is a cool water rinse or soak before the wash.
Do not put hot water on a salt ring before it has been rinsed, since that drives the salt and the road grime carried with it deeper into the weave.
Salt crystals are abrasive when dry. Cloth that is splashed, dried and worn again all season wears at the hem long before it wears anywhere else.
The grit that comes with the salt is essentially sand, and it settles at the bottom of the drum. Give salted items a wash of their own rather than distributing that grit through everything else.
Boot liners and glove linings collect the same mixture and are usually forgotten until they smell.
The Fargo part
Winters here are severe enough that none of the above is marginal. It is the normal condition for a large part of the year rather than a cold snap to wait out.
Long stretches of below zero weather mean indoor air stays very dry for months, so static and brittle cloth are a season long condition rather than an occasional annoyance. Lower dryer heat and shorter cycles do more about it than any additive on a shelf.
A long winter also means winter clothing is in constant rotation rather than worn a handful of times. Coats, snow trousers and heavy layers get washed repeatedly through the season, and those are precisely the items that need the most drum space and the longest drying.
Salt on roads and walkways runs for months here, so hems take that treatment continuously instead of a few times a year. Rinsing salt out promptly, before it dries hard and before hot water touches it, is most of the difference between a coat that lasts several winters and one that does not.
Where the heavy winter things dry
Coats, snow gear and heavy layers need a drum with room to move and a dryer that can finish the job in one go.
The machines at our self-service laundry on 45th Street South hold enough water for a quilted coat to rinse right through, and the drum size lets bulky winter layers tumble instead of packing into a wet lump.
Our machines and the store are cleaned daily.

For general guidance, The American Cleaning Institute publishes a fabric care guide that is a useful cross-check.
The short version
Below zero weather makes indoor air extremely dry, and that dryness is behind most winter laundry trouble. Static builds because there is no moisture to carry the charge away, so stop overdrying and keep synthetics away from cotton. Stiff cloth is either overdrying or detergent residue, and a wash with no detergent tells you which. Leave with laundry genuinely dry, in closed bags, because damp fabric freezes and frozen fabric cracks at a fold. Insulated coats and heavy layers hold water right through and need their own long dry. Rinse salted hems in cool water before anything warm touches them.
