How to Wash Newborn Clothes: A Step-by-Step Guide for New Parents
The short answer: wash all new baby clothes once before your newborn wears them, using a non-biological detergent at 30-40 degrees C. Use cold water on milk stains before they set, skip fabric softener entirely, and dry on a rack rather than tumble drying where possible. The ATTITUDE Baby Laundry Detergent is fragrance-free, plant-based, and specifically formulated for newborn skin, making it a safe default choice for the first few months.
- Newborn clothes need one wash before use to remove manufacturing chemicals, dyes, and shipping residues
- Use non-biological detergent at 30-40 degrees C for everyday washing, 60 degrees for heavily soiled items
- Rinse milk and food stains in cold water immediately, apply a baby-safe stain remover, then wash as normal
- Skip fabric softener and dryer sheets, they leave a residue that can irritate newborn skin

There is a surprising amount to know about washing your baby's first load of clothes. New clothing arrives treated with chemical sizing agents, anti-mould finishes, and residual dyes from the factory floor. Your newborn's skin is roughly 30% thinner than yours and far more reactive, which means those residues matter in a way they never did for your own wardrobe.
The good news is the process is simple once you know the rules. Here's exactly how to wash newborn clothes safely, from the first pre-birth load through the day-to-day routine once your baby arrives.
Why New Baby Clothes Need Washing Before Use
Every new garment, whether it cost £3 or £30, goes through the same manufacturing pipeline. Fabric is treated with sizing agents to keep it crisp during cutting and sewing, then treated again with anti-mould and anti-static finishes for shipping. Dyes, especially on coloured items, carry residual chemicals that sit on the fabric surface.
A newborn's skin absorbs these residues more readily than adult skin. The NHS recommends washing all new clothing before your baby wears it, and this applies to everything from vests and sleep suits to blankets and muslin cloths. Even items that feel soft and pre-washed benefit from a rinse.
Step 1: Sort and Check Before Washing
Before anything goes in the machine, sort your baby clothes into two piles: whites/light colours and darker colours. Wash them separately, the same as you would your own clothes, to prevent dye transfer onto pale fabrics.
Check each item for loose threads, sharp labels, or snap fasteners that could scratch. Trim any long threads and cut out scratchy care labels, leaving enough of the tag to read washing instructions if you need them later. Turn zip-up items inside out so the metal teeth don't rub against other garments in the wash.
Step 2: Choose the Right Detergent
This is where most new parents overthink it. You need a detergent that is fragrance-free, dye-free, and designed for sensitive skin. Non-biological detergent is the standard recommendation for newborns because it contains fewer enzymes that can trigger skin reactions.
The ATTITUDE Baby Laundry Detergent is plant-based, EWG verified, and unscented, which makes it one of the safer choices for the first few months. It works at 30-40 degrees C and handles everyday baby messes well. If you need a larger supply, the ATTITUDE Refill (80 loads) works out cheaper per wash.
Use less detergent than you think you need. Overdosing leaves residue in fabric that stays trapped after rinsing, and that residue is one of the most common causes of skin irritation in newborns. Follow the dosage on the bottle and err on the lower side for the first few loads.
Step 3: Set the Right Temperature
For everyday baby clothes, 30-40 degrees C is enough. This removes dirt and bacteria without shrinking cotton or damaging elastic. Save the 60 degree wash for items that need a deeper clean, like bibs with dried-on food, muslin cloths with sick, or anything with a stubborn stain.
Always check the care label first. Most baby clothes are cotton or cotton-blend and handle 40 degrees fine, but some merino or bamboo items need cooler washes. When in doubt, 30 degrees is always safe.
Use a gentle or delicate cycle if your machine has one. The slower spin speed is kinder to small garments and reduces the risk of elastic stretching in things like sleep suits and sleeping bags.
Step 4: Handle Stains Before They Set
Milk, formula, and breast milk stains are the most common baby laundry challenge. The key is speed: rinse the stained area under cold running water as soon as you spot it. Hot water sets milk protein into the fabric, making the stain much harder to shift later.
After rinsing, apply a baby-safe stain remover directly to the mark. The ATTITUDE Baby Stain Remover Spray is fragrance-free and plant-based, designed for exactly this. Spray it on, let it sit for 15-30 minutes, then wash the item as normal. For stubborn stains, the Tough Love Stain Remover Granules can be added to the wash drum alongside your detergent.
Yellow-tinged milk stains on white cotton can be treated with a paste of bicarbonate of soda and cold water. Apply it to the stain, leave for 30 minutes, then wash. This is a reliable household method that costs almost nothing and works surprisingly well.
Step 5: Drying Done Right
Air drying is gentler on baby clothes than tumble drying. Cotton shrinks and elastic degrades faster with heat, so use a drying rack or a clothes horse in a well-ventilated room. Lay flat anything with stretch in it, like leggings or sleep suits, to prevent the elastic from going wonky.
If you do use a tumble dryer, choose the lowest heat setting and remove items while they're still slightly damp. Over-drying makes cotton stiff and rough against your baby's skin. A changing bag with a zip pouch is handy for storing a spare outfit that's been tumble-dried and might need a quick re-dampening to soften it up.
Step 6: What to Skip Entirely
Fabric softener. Skip it. Softener works by coating fibres in a thin layer of chemicals that make them feel smooth. That coating traps detergent residue and reduces the breathability of cotton. For a newborn, the residue left behind is a more likely irritant than the softness is a benefit.
Dryer sheets. Same problem as softener, just in a different form. They leave a waxy film on fabric that builds up with repeated washing.
Washing your baby's clothes with heavily scented adult laundry. For the first few weeks, wash baby clothes separately. Even with a rinse cycle, strong detergent fragrances from adult loads can linger in the drum and transfer to baby items.
Building a Simple Laundry Routine
Once your baby arrives, the laundry piles up fast. A practical routine keeps it manageable:
Daily: Collect all soiled items into a dedicated baby laundry basket. Rinsing stains immediately prevents them from setting. A quick spray of stain remover on milk or food marks takes under a minute.
Every 2-3 days: Run a full load at 30-40 degrees with non-bio detergent. This prevents the dirty basket from developing a smell and keeps a steady supply of clean clothes available.
Weekly: Do a 60 degree wash for heavily soiled items like bibs, muslins, and anything with a persistent stain. This deep-clean cycle handles bacteria that the cooler washes miss.
The essential newborn products list includes a few laundry items that make the routine easier, including a stain spray and a decent drying rack.
Frequently Asked Questions
Do you really need to wash newborn clothes before use?
Yes. New clothing is treated with chemical sizing agents, anti-mould finishes, and dyes during manufacturing and shipping. These can irritate a newborn's sensitive skin. Washing before use removes these residues and any dust from storage and transport.
What temperature should I wash baby clothes at?
For everyday washing, 30-40 degrees C is fine for most baby clothes. Use a 60 degree wash occasionally for items that need thorough sanitising, like bibs and muslins, but check garment labels first as some fabrics shrink at higher temperatures.
Should I use biological or non-biological detergent for baby clothes?
Non-biological detergent is generally recommended for newborn clothes. It contains fewer enzymes that can irritate sensitive skin. Bio detergents work well for stain removal, but the added enzymes are the most common trigger for skin reactions in babies under six months.
How do you remove milk stains from baby clothes?
Rinse milk-stained clothes in cold water as soon as possible. Apply a baby-safe stain remover directly to the mark, let it sit for 15-30 minutes, then wash at 30-40 degrees C. Avoid hot water on milk stains as heat sets the protein into the fabric.
Can I wash baby clothes with adult clothes?
It is fine to wash them together once your baby is a few months old and their skin is less reactive. For the first few weeks, washing baby clothes separately in a gentle, fragrance-free detergent reduces the risk of irritation from residue left on adult clothing.
