The short answer

Mould on clothes and belongings can usually be cleaned, but handle it carefully and treat the damp that caused it. Take affected items outside if you can, brush off loose mould in the open air to avoid spreading spores indoors, then wash clothing on the warmest setting the fabric allows. Protect yourself with gloves and a mask. Some heavily affected or porous items may need to be thrown away. Most importantly, fix the damp — usually condensation in a wardrobe or against a cold wall — or the mould will return.

Mould does not only appear on walls — it turns up on clothes in a wardrobe, on shoes, books, fabric and stored belongings, often where air cannot circulate against a cold surface. The good news is that many items can be saved with careful cleaning. The important part, as ever, is to fix the conditions that let mould grow. This page explains how to deal with affected belongings safely and how to stop it happening again. It is general guidance; protect yourself, especially if you are vulnerable.

Mould on belongings at a glance

Why mould grows on clothes and belongings

Mould needs moisture, and stored belongings provide perfect conditions when air cannot circulate: a wardrobe against a cold external wall, boxes in a damp cupboard, or fabric pressed against a wall where condensation forms. Natural fibres and porous materials — cotton, wool, leather, paper, cardboard — hold moisture and feed mould readily, which is why a leather jacket or a stack of books often shows it first. So the appearance of mould on clothes is usually a sign of a damp, poorly ventilated micro-climate, not just bad luck, and it tends to point to a wider damp problem in that part of the room.

How to clean affected items safely

Most washable and hard items can be saved if you act carefully and protect yourself from spores:

ItemApproachIf badly affected
Washable clothesBrush off outside, wash warm, dry fullyRepeat wash; bin if marks won’t shift
Leather shoes / bagsWipe, clean, dry thoroughlySpecialist clean or replace
Books / paperDry, brush gently outsideOften easier to discard
Soft furnishings / mattressesClean surface, dry fullyReplace if mould is deep-set
Some things are not worth saving: heavily affected porous items — old cardboard, paper, deep-set mould in soft furnishings — can be impossible to clean fully and may be safer to throw away. If you are vulnerable or the amount is large, ask someone else to handle it.

When to throw items away

Not everything can be saved. Porous items where mould has taken hold deep in the material — old books, cardboard boxes, some soft furnishings or mattresses — may be impossible to clean fully, and discarding them is often the safest choice. Use your judgement: if repeated washing does not shift the mould, or the item is low-value and badly affected, dispose of it carefully in a sealed bag so spores are not spread on the way out of the home. For valuable items such as leather goods, a specialist clean may be worth the cost before you give up on them.

Stop it happening again

Cleaning the items is only half the job — the conditions that caused the mould need to change, or it will return. Practical measures:

If you rent, recurring mould on your belongings is often a sign of an underlying damp problem the landlord should address, not simply a matter of how you store your things — see mould in a rented property for your position. And for cleaning mould on the wall behind affected items, which is usually the real source, see how to clean mould safely. Fixing that wall is what stops your clothes and belongings being affected again.

Mould on your clothes or belongings?

Clean what you can safely, discard what you can’t, and fix the damp behind it — ventilate wardrobes and keep items off cold walls. A survey can find a persistent cause.

Frequently asked questions

Can mould be washed out of clothes?

Often, yes. Brush off loose mould outdoors first, then wash affected clothing on the warmest setting the care label allows, with a suitable detergent, and dry fully. Repeat if marks remain. Wear gloves and a mask, and discard items where the mould will not shift.

Is mould on clothes dangerous?

Mould on belongings carries the same general risks as mould elsewhere — mainly respiratory and allergic. Handle affected items carefully, protect yourself with gloves and a mask, and work outdoors where possible to avoid spreading spores. Vulnerable people should ask someone else to do it.

Should I throw away mouldy belongings?

Many washable or hard items can be cleaned, but heavily affected porous items — old paper, cardboard, deep-set mould in soft furnishings or mattresses — can be impossible to clean fully and may be safer to discard. Use your judgement on value and how badly affected they are.

How do I stop mould growing on clothes in the wardrobe?

Improve airflow — don’t overfill the wardrobe, keep it slightly away from cold external walls, and reduce indoor humidity. Avoid putting damp clothes away, and ventilate the room. For persistent damp behind the wardrobe, get a qualified survey to find and fix the cause.
