No, cloth nappies should not smell when they are stored properly and washed with a good routine. If cloth nappies smell strongly of urine, ammonia, or musty laundry, it usually means the wash routine or storage method needs adjusting. Waladi makes cloth nappy care simpler with pocket-style nappies, absorbent inserts, wet bags, and easy everyday sets that are simple to wash and reuse.
A clean cloth nappy should smell clean after washing. A used nappy may smell like wee or poo before wash day, but it should not have a strong smell after it has been washed and dried.
The main causes of cloth nappy smells are leaving nappies too long before washing, not enough airflow while storing them, not using enough detergent, or using a wash cycle that is too short or too light for dirty nappies.
Why do cloth nappies smell?
Cloth nappies usually smell because urine and soiling have not been fully removed before they are reused.
The most common causes are:
- Not washing often enough: Dirty nappies left too long can develop stronger smells.
- Not enough airflow: Sealed storage can trap moisture and make smells worse.
- Too little detergent: Nappies are heavily soiled items and need enough detergent to clean properly.
- A weak wash cycle: A quick or gentle wash may not be enough for absorbent inserts.
- Ammonia build-up: Urine can break down into ammonia if nappies are not washed well or quickly enough.
What should clean cloth nappies smell like?
Clean cloth nappies should smell neutral. They should not smell like urine, ammonia, musty laundry, or old washing.
If they smell clean out of the machine but smell strong as soon as your baby wees, that usually means urine is still trapped in the fibres or the wash routine needs improving.
How do you stop cloth nappies from smelling?
The simplest way to prevent smells is to wash regularly, store dirty nappies with airflow, and use a proper wash routine.
- Store used nappies in a dry pail, airy basket, or open wet bag until wash day.
- Do not soak dirty nappies in water.
- Wash every 1-2 days where possible.
- Use enough detergent for heavily soiled laundry.
- Use a proper main wash, not only a quick rinse.
- Make sure inserts are fully dry before storing them away.
Waladi waterproof wet bags can help when you are out, at daycare, or storing nappies before washing. For home storage, airflow is still important, so avoid sealing dirty nappies tightly for too long.
Do cloth nappies smell like ammonia?
They should not. A strong ammonia smell usually means urine has broken down in the nappy before it has been washed out properly.
Ammonia can happen when nappies sit too long, stay too wet in storage, or are not cleaned deeply enough during washing. If you notice a strong ammonia smell, review your wash routine first.
Night nappies and heavily wet nappies may need more attention because they hold more urine for longer.
Do wet bags smell?
Wet bags can smell if dirty nappies are sealed inside for too long or if the wet bag is not washed regularly.
For short outings, a zipped wet bag is useful and practical. For longer storage at home, airflow helps reduce trapped moisture and odour.
Wash your wet bag regularly with your nappies so it stays fresh too.
