The gap between almost dry and dry is small enough to be invisible and large enough to cause most of the laundry problems people have. It is behind musty towels, drawers that smell, clothes that seem to go stale quickly, and loads that have to be washed twice.
Fabric that is ninety five percent dry feels dry. That last five percent is where everything goes wrong.
Why the last part is so hard to see
Fabric dries from the outside in and from the thin parts to the thick parts.
The flat panel of a shirt is dry long before the seams are. A hoodie can have completely dry sleeves and a waistband that is still holding water. Towels dry at the surface and stay damp in the pile. Pockets are two layers plus a seam and they are the last thing in any garment to dry.
So the hand test people use, running a palm over the surface, tests the part that dried first. It tells you almost nothing about the part that matters.
Warm fabric also feels drier than it is. A load pulled from a dryer is warm, and warmth reads as dryness to the hand. The same load assessed twenty minutes later, cool, often feels faintly damp in the thick parts, and that is the honest reading.
What almost dry actually causes
Folded and stacked in a drawer, damp fabric has nowhere to release moisture and the stack develops a smell within a week or two. Nothing is wrong with the wash.
In a closed wardrobe, the same, and it spreads to whatever is next to it.
Towels are the worst case because they are thick, they are folded, and they go into a bathroom, which is the most humid room in the house. A towel that went into the cupboard slightly damp is the classic source of the smell people blame on their machine.
And left long enough in the right conditions it goes beyond smell to actual mildew, which stains and which is far harder to remove than it would have been to dry the load properly.
How to test properly
Let the load cool for a few minutes before judging it.
Then check the thick parts specifically and only those. Waistbands, cuffs, hems, collar bands, pocket layers, the double-stitched seams on a towel, and anywhere a label is sewn in. Press between finger and thumb rather than running a hand across.
Check the heaviest item in the load rather than the first one you pull out. Loads dry unevenly and a mixed load dries very unevenly.
If anything is questionable, the whole load goes back in for ten minutes. Ten minutes of extra tumble costs very little compared with rewashing.
Getting it right in the machine
Sort by weight, and this matters more for drying than for washing. Towels and jeans take much longer than shirts, so a mixed load either bakes the light items or leaves the heavy ones damp. There is no setting that solves that.
Use the moisture sensor rather than a timer where the machine has one, since a sensor stops when the load is dry and a timer stops when the clock says so.
Do not overfill. Air has to move through the load, and a packed drum tumbles as a single mass with a damp core.
Clean the lint screen every load. A restricted screen makes the dryer run longer, hotter, and less effectively, and if you have been using dryer sheets the screen may be coated with an invisible film. Run water onto it. If the water beads or sits rather than falling straight through, scrub it with a brush and warm soapy water.
And check the outside vent occasionally, because a blocked duct is the most common reason a dryer stops drying properly.
Air drying, where this is a bigger risk
Indoor air drying gets fabric to almost dry fairly quickly and to genuinely dry very slowly, which is exactly the trap.
Space items out with air on both sides rather than doubling them over a rail, where the two faces touch and never dry.
Move air across them with a fan, which does more than heat does.
Give it much longer than seems necessary, and turn thick items over partway through.
And finish thick items in a dryer for fifteen minutes if you have the option. That is the reliable way to close the gap.
The Kent part
This is the local problem, and it is worth being direct about it.
From roughly November through March the outdoor air here is frequently carrying more moisture than the laundry is. Hanging washing outside in those months does not dry it, and in some conditions adds water to it. Even indoors, an unheated room in a Pacific Northwest winter will hold a rack of laundry at almost dry for days.
So through the wet half of the year, air drying needs a heated room, moving air, and considerably more time than people expect, and thick items realistically need a dryer to finish.
June through September is genuinely different. The dry season here is properly dry and outdoor drying works as well as anywhere, with the same caveat as everywhere else about keeping dark and stretchy items out of direct sun.
The other winter factor is that a house closed up against the rain has less air exchange, so a wardrobe or a drawer in a bedroom is a stiller, damper box than it is in July. Almost dry laundry going into that has a shorter run before it starts to smell.
When the dryer is the bottleneck
Most home dryers are too small and too slow for the loads that need drying most, which are the thick ones. A comforter, a stack of towels, or a week of heavy clothing needs volume and time, and a small drum gives it neither.
The machines at our self-service laundry on Pacific Highway South spin at higher extraction speeds, so loads come out of the wash with far less water in them to begin with, and the dryers have the capacity to get thick items completely dry rather than nearly dry.
Our machines and the store are cleaned daily.
Our wash-dry-fold service covers the loads you would rather not chase around all evening.
The short version
Fabric dries from the thin parts to the thick parts, so the surface tells you nothing. Let a load cool before judging it, because warm fabric feels drier than it is, then check waistbands, cuffs, hems, pockets, and seams by pressing rather than running a hand across. Check the heaviest item, not the first one out. Sort by weight for drying, use the moisture sensor rather than a timer, and clean the lint screen every load, testing it under water for a dryer sheet film. When in doubt give it ten more minutes. And through the wet half of the year here, air drying needs a heated room, a fan, and far more time than it feels like it should.
