From about October to May, the outdoor drying rack is decorative. It is not that it rains constantly, though it does rain a lot. It is that the air itself stays damp enough for months that wet fabric hung outside does not really dry, it just stays wet in a different location.
Which leaves everyone here doing the same thing: drying laundry indoors, in a house that is already carrying more moisture than it wants, through the exact season when the windows stay shut.
That combination is how Pacific Northwest houses end up with a musty smell, and bedding is usually where it shows up first.
The mistake almost everyone makes
Air drying laundry indoors in winter feels thrifty and sensible. In this climate it is frequently the thing causing the problem you are trying to solve.
A single load of wet laundry holds a surprising amount of water, and all of it has to go somewhere. Indoors, in a closed house, it goes into your air. Air drying one load of bedding a week through a wet winter is a meaningful amount of moisture added to a house that already struggles to shed it.
That raises the humidity in the room, and higher humidity means everything else in the room dries more slowly, including the bed you sleep in. It compounds.
If you are going to air dry indoors here, do it in a room with a running extractor fan or a dehumidifier, and not in the bedroom.
Why the bed goes musty here
Mildew does not need standing water. It needs fabric that stays damp, and in a cool damp climate the bar is easy to clear.
You put moisture into the bed every night. In a dry climate that evaporates away during the day. Here, in a closed bedroom in February, the air has limited capacity to take it, so the bed never fully dries between nights. Over weeks that becomes a smell, and the smell is biological rather than cosmetic.
Cool damp is a different problem from hot humid, and the fix is different too. Heat is not doing the drying for you, so airflow has to.
The habits that actually work here
Leave the bed open every morning. Pull the covers all the way back rather than making it, and give it at least half an hour. A bed made at seven traps the whole night’s moisture under the comforter until bedtime. This is free and it is the biggest single change available.
Run the bedroom door open and a fan going during the day. Airflow is what you have instead of dry air.
Use the bathroom extractor fan properly. Twenty minutes after a shower, not two. A great deal of the moisture load in a Pacific Northwest house comes from showers that were never fully vented, and it migrates through the house to the coolest surfaces.
Consider a dehumidifier for the bedroom in winter. Aim for under 50 percent. It also happens to make dust mites considerably less comfortable, since they need humidity above roughly that level to survive.
Do not push furniture flat against exterior walls. Those walls run cold, cold surfaces collect condensation, and a headboard or dresser pressed against one creates a pocket with no air movement. A couple of inches of gap makes a real difference.
Never leave a finished load sitting in the washer. In a cool damp house a wet load turns fast, and that smell transfers to everything you dry with it.
Washing so it does not come back
Cold water is the default advice everywhere and it is wrong for bedding here. Cold does not remove body oil, and body oil is what mildew and odor bacteria feed on. Wash bedding warm, and hot when something has already picked up a smell, within what the care label allows.
Half a cup of white vinegar in the rinse cycle, routinely. It is mildly acidic, which breaks down the residue that holds odor rather than covering it.
Use less detergent than the cap suggests. Residue is food.
Skip fabric softener on bedding. It coats fibers and slows their ability to release moisture, which in a damp climate is precisely backward.
Clean the washer itself once a month. Front-loaders here develop mildew in the door gasket, and a machine that smells will pass that to everything in it. Wipe the gasket dry after use and run an empty hot cycle with vinegar monthly.
Drying is where this gets solved
Use the dryer for bedding here, fully, rather than pulling things out to finish on a rack. Give heavy items considerably more time than the surface suggests, and check by squeezing the thickest part rather than touching the outside. Cool in the middle means wet in the middle.
The item that defeats home equipment is the comforter. A home dryer packed with one cannot tumble it, so the outside dries and the core does not, and the core is exactly where a musty smell starts and where it survives every subsequent wash.
The machines at our self-service laundry on NE Vancouver Mall Drive have the drum size for a full comforter to move freely and a much higher extraction speed, which pulls out far more water before drying even starts. For bedding that has already gone musty, that combination is usually what resets it, and it is the reason to bring a comforter here rather than fight it at home through a wet winter.
Nou wash-dry-fold service covers bedding if you would rather not manage it.
The short version
Stop air drying laundry indoors in winter, because you are adding the moisture that keeps your bed from drying. Leave the bed open every morning rather than making it, and run a fan. Vent showers properly and consider a bedroom dehumidifier under 50 percent. Wash bedding warm rather than cold, with vinegar in the rinse and no softener, and clean the washer gasket monthly. Dry everything fully and squeeze the middle before you trust it.
