How to Wash Newborn Baby Clothes with Detergent? | The First Wash

Wash newborn clothes before the first wear using a gentle, fragrance-free detergent and an extra rinse cycle.

Newborn skin is thinner and more sensitive than an adult’s, so the questions around how to wash newborn baby clothes with detergent come down to one goal: leaving zero residue that could irritate delicate skin. HealthyChildren.org, the American Academy of Pediatrics’ official parenting site, recommends washing all new clothes before your baby wears them. The good news is this doesn’t require a special routine or expensive products — just the right detergent, a few sensible choices, and one test before you commit to a switch.

Is Baby Detergent Really Necessary?

No. HealthyChildren.org notes that “baby detergents” are commonly recommended because they may leave fewer residues on fabric, but the organization does not require one. The real concern is what’s left behind after the wash — fragrance and chemical residue — not the label on the bottle.

What matters is choosing a detergent that is gentle and free of dyes and perfumes. Many standard “free and clear” detergents fit this description and are significantly cheaper than specialty baby brands. If you already use a fragrance-free detergent for your own sensitive skin, it will very likely work fine for your newborn’s clothes too. If you decide to add a dedicated baby detergent, that’s fine as well — just know it’s an option, not a rule.

Wash Newborn Clothes: The Step Order That Works

Follow this order for the first wash and every wash after:

• Sort and prep. Separate baby clothes from heavily soiled items like cloth diapers or clothes stained with grease. Turn anything with prints or snaps inside out to protect the fabric.
• Choose your detergent dose. Use the amount listed on the bottle for a normal load. More soap doesn’t mean cleaner clothes — it means more residue left on the fabric.
• Run the cycle. Wash in the warmest water the garment’s care tag allows.
• Add an extra rinse. This is the single most effective step for sensitive skin. An extra rinse cycle pulls out any soap the first rinse left behind.
• Check the result. When the load finishes, take a garment out and sniff it.

If you’re switching from a scented detergent to a fragrance-free one, test one garment first. Nemours KidsHealth recommends washing a single item, having your baby wear it, and watching for any skin reaction before you commit to the switch. If redness or irritation appears, stop using that detergent.

What Products To Skip and When To Wash Separately

Two product categories should stay out of the baby laundry routine entirely: fabric softeners and anti-static sheets. KidsHealth advises avoiding both because the chemicals and fragrances they deposit on fabric can irritate newborn skin. From the first wash onward, skip them completely.

Washing baby clothes separately is a common recommendation, but it’s not a strict rule for every family. HealthyChildren.org describes separate washing as standard advice rather than a requirement. The exception: babies with eczema, allergies, or other sensitive-skin conditions. For those babies, KidsHealth says washing their clothes separately from the family laundry is less likely to trigger irritation. For everyone else, mixing baby clothes into a normal family load is usually fine — as long as the detergent is fragrance-free and the extra rinse is on.

Once your baby’s skin proves tolerant, washing on a regular family schedule saves time and water. Many parents do a dedicated newborn laundry day in the first few weeks, then shift to mixing loads once their pediatrician confirms the baby’s skin is handling the routine well. One rule that never changes: fragrance-free, residue-free, extra rinse — every single load.

Between washes, air-drying baby clothes indoors extends their life and avoids the heat damage a dryer can cause.
