Most winter cleaning advice talks about windows, bathrooms and floors, and skips straight past the two places where a lot of Adelaide homes actually develop their first musty smell: the wardrobe and the linen cupboard. Both are closed boxes, packed tight with fabric, and often sitting against an exterior wall that is colder than the rest of the room.
Give that combination a few weeks of a sealed-up July and the doonas, jumpers and spare linen inside can start to smell stale before anyone notices, sometimes with the first spots of mildew close behind. This guide covers why it happens, how to store things properly this winter, and how to keep the smell out of your home altogether.
The Golden Rule: Nothing goes into storage unless it is completely clean and completely dry. Almost every musty wardrobe traces back to one damp or unwashed item packed away in a space with no airflow to dry it out.
Why Wardrobes Turn Musty in Winter
A wardrobe or linen cupboard is one of the least ventilated spaces in the house on a normal day, and winter makes it worse. From the older weatherboards of the Adelaide Hills to newer builds on the coastal plains, the pattern is the same: doors stay shut for warmth, the exterior wall behind the cupboard runs cooler than the room, and moisture that would otherwise drift away has nowhere to go.
Working Against You
- Cupboards against an outside wall run colder than the rest of the room
- Closed doors mean almost no airflow to carry moisture back out
- A packed-tight rail or shelf leaves no gap for air to move between items
What Feeds the Smell
- Winter clothes packed away slightly damp from a last-minute wash
- Sealed plastic tubs and bags trapping whatever moisture is already there
- General household humidity settling into the coolest, stillest corner of the room
Pro Tip: If you can smell must the moment you open a wardrobe or cupboard door, that is trapped humidity talking. It is far easier to fix with airflow now than once it has turned into visible mildew.
Set Up Smart Winter Storage
None of this needs a wardrobe renovation. Most musty storage comes down to two habits: what you put things in, and how much you cram into the space. Fix those two and airflow does most of the rest of the work on its own.
Choose Breathable Storage
- Cotton garment bags, pillowcases or cardboard boxes instead of sealed plastic tubs
- A small moisture absorber or a few silica gel packs in enclosed drawers and boxes
- Cedar blocks or lavender sachets for a light, natural scent that also discourages moths
Leave Room to Breathe
- Fill rails and shelves to about three-quarters, not floor to ceiling
- Leave a small gap between the back of the cupboard and stacked items
- Stand under-bed boxes on small risers rather than flush against the floor
Pro Tip: A cheap moisture absorber tub, checked and emptied every few weeks, does more for a musty cupboard than any amount of air freshener sprayed over the top of the smell.
The Winter Changeover Routine
Swapping summer and winter wardrobes is the perfect moment to break the musty cycle, because everything is out of the cupboard anyway. Work through these three passes as you go, in order.
🔍 Empty, Inspect, Wash
- Take everything out and check for damp patches, spotting or a musty smell before anything goes back in
- Only pack away items that are completely clean and completely dry, never a quick fold of something worn once
- Deal with any early mildew now, while it is still a small, treatable patch
🧺 Pack It Loosely
- Swap sealed plastic tubs for breathable cotton bags, pillowcases or cardboard boxes
- Fill each space to about three-quarters, leaving room for air to move between items
- Label boxes so you're not re-opening every one later just to find what you need
🌬️ Give It Ongoing Air
- Crack the doors on any dry, sunny winter day for an hour to clear trapped humidity
- Wipe down the empty cupboard interior before restocking it, so nothing goes back onto a damp surface
- Check moisture absorbers or silica packs every few weeks and empty or replace them once full
Best Value Trick: The airing-out step costs nothing and takes an hour. It is the single most overlooked step, and often the only one that actually matters once everything else is done properly.
Keep Cupboards Fresh All Winter
A changeover fixes the moment things go into storage. Staying fresh through the rest of winter comes down to a few small habits that take minutes, not a weekend.
Weekly Habits
- Give the current-season wardrobe a quick glance for any early spotting
- Hang damp coats and scarves elsewhere to dry fully before they go back on the rail
- Leave a little space between hangers rather than packing the rail tight again
Monthly Habits
- Wipe down cupboard interiors and skirting with a dry or lightly damp cloth
- Check and refresh moisture absorbers before they overflow
- Pull under-bed boxes out for a look, since that's the spot people check least
Pro Tip: Do the cupboard check on the same day you do the rest of your winter air quality routine. It only adds a few minutes and keeps musty smells from building up unnoticed between seasons.

Frequently Asked Questions
Q.Why does my wardrobe smell musty in winter?
A wardrobe is a closed box with little airflow, and in an Adelaide winter the air around it is already damp. Any moisture left in stored fabric, or that seeps in through an exterior wall, has nowhere to go, so it settles into clothes and timber and starts to smell musty. Packing it too full makes it worse, since air can't move between items to dry the space out.
Q.Is it safe to store clothes in plastic bags over winter?
Sealed plastic is one of the most common causes of musty, mildewed winter storage. Any trace of dampness left in the fabric gets trapped against itself with nowhere to evaporate to, and mildew can take hold within weeks. Breathable options like cotton garment bags, pillowcases or cardboard boxes let residual moisture escape instead of pooling against the fabric.
Q.How do I get rid of mildew spots on stored clothes or linen?
Take the item outside and brush off any dry mould first so you're not spreading spores indoors. Wash it on the warmest safe cycle for the fabric, adding an extra rinse, then dry it completely in the sun or with good airflow before it goes anywhere near a cupboard again. If the smell or staining lingers after washing, it may need a specialist fabric clean rather than another home wash.
