How to wash washable nappies
Quick summary
To properly wash reusable nappies , only two cycles are needed: a pre-wash in cold water to remove residue, followed by a main wash at 40–60°C with a compatible detergent . No need for harsh products: a good rinse and a regular routine guarantee absorbency, hygiene, and longevity.
Questions that parents actually ask themselves
- Should nappies be washed at 60°C?
- Can I mix everything with my laundry?
- How to avoid bad smells?
- Which laundry detergent is compatible?
- How often should I wash?
Summary
The principle: a wash in 2 cycles
Our official method — also presented in the 2026 washing method — is based on two simple cycles validated by thousands of families:
- Cycle 1: cold pre-wash → remove urine and feces
- Cycle 2: Main wash → clean, sanitize and preserve absorbency
This routine prevents leaks , odors, and fouling.
Cycle 1 – Cold wash
Pre-washing removes 90% of dirt and prepares the laundry for optimal cleaning.
- Temperature: cold or 30°C
- Program: cotton or mixed
- Duration: ≥ 30 minutes
- Objective: rinse, loosen residues, prepare for the main cycle
The machine should be half full for proper mixing.
Cycle 2 – Main wash 40–60°C
This cycle ensures complete sanitation and preserves absorption capacity.
- 40°C daily, 60°C occasionally
- Cotton program (1.5 to 2 hours)
- Spin speed 800–1200 rpm
- Non-greasy, fabric softener-free laundry detergent
A machine filled to 3/4 ensures ideal mixing and effective rinsing.
Which laundry detergent should I use?
Laundry detergent plays a vital role: a formula that is too greasy can lead to buildup and loss of absorbency.
Consult the list of compatible laundry detergents.
How often should the nappies be washed?
- Every 2 days
- 1 day out of 3 if you have a high turnover
- Never store for more than 72 hours if the storage container is not completely dry → risk of bacteria

How do you dry washable nappies?
Drying time depends on the material:
- Inserts: tumble dry low possible
- TE2 with basket: air drying to preserve the PUL
- Avoid: radiators, prolonged direct sunlight
See also: optimal storage .
Common mistakes to avoid
These errors often occur in cases of leaks or odors:
- Using white vinegar → weakens the PUL
- Greasy detergents → buildup
- A single long cycle → residue and odors
- Machine too empty → poor mixing
- Fabric softeners → decreased absorption
If the odors persist: see cleaning & fouling .
FAQ – Washing washable nappies
Can I wash washable nappies with the rest of my laundry?
Yes, provided that cycle 1 was done separately. The main wash can be combined.
How often should I clean it?
Only in cases of odor or decreased absorbency. With a good routine, this remains rare.
Can I use the tumble dryer?
Yes for inserts . For TE2 diapers, air drying is preferable to preserve the waterproof membrane.
Why do my diapers smell so bad?
Common causes: machine too empty, greasy detergent, insufficient rinsing or only one cycle.
