Should You Wash New Clothes Before Wearing Them?
, by Hello Charlie Blogs, 3 min reading time
That crisp new shirt may look ready to wear, but a first wash is often a sensible step—especially for baby clothes, underwear, sleepwear and anything worn close to sensitive skin. It removes loose dye, finishing residues, dust and traces left by manufacturing, transport or handling.
Quick answer: wash new baby clothes, underwear, swimwear, bedding and close-fitting garments before use. For coats or specialist items that cannot be washed normally, follow the care label and air them before wearing. There is no need to disinfect every new garment.
Why wash new clothes?
Textiles pass through factories, warehouses, packaging and shops before reaching you. Depending on the fibre and finish, a new item may carry loose colour, lint, sizing agents or an odour from packaging. Most people will not have a problem, but a wash can reduce avoidable contact—particularly if you have eczema, fragrance sensitivity or a history of textile contact dermatitis.
This is a practical precaution, not proof that all new clothes are “toxic”. The chemistry, amount of residue, route of exposure and a person’s sensitivity all matter.
Which items should always get a first wash?
- Baby clothes, wraps and bedding: babies have delicate skin, and prewashing also lets you check fit, shrinkage and colourfastness.
- Underwear, socks and swimwear: these sit against warm or intimate skin.
- Sheets, towels and face cloths: washing removes lint and can improve absorbency.
- Dark or brightly dyed clothing: a separate first wash helps prevent colour transfer.
- Second-hand clothes: wash when the care instructions allow, then dry completely before use.
A structured coat, formal garment or dry-clean-only item may not need a home wash. Air it in a well-ventilated place and follow the label instead of risking damage.
How to wash new clothes
- Read the care label and check pockets, trims and fastenings.
- Separate whites, pale colours and strong colours for the first wash.
- Use the coolest effective cycle and the correct detergent dose.
- Choose a fragrance-free detergent if anyone in the household has sensitive skin.
- Run an extra rinse if the item still feels soapy or if skin is very reactive.
- Dry fully before storing or wearing.
More detergent does not mean cleaner clothing. Overdosing can leave residue and makes rinsing harder. Disinfectant, antibacterial rinse and fabric softener are not routinely required for brand-new clothes.
What if the colour runs?
Wash the item separately according to its label until excess colour stops transferring. If dye stains skin, upholstery or other clothing after correct washing, stop wearing it and contact the retailer. A strong chemical odour that persists after airing and washing is another reasonable reason to return the item.
What if a rash appears?
Stop wearing the garment and gently wash the affected skin. Seek advice from a pharmacist, GP or dermatologist if a rash is painful, widespread, blistering, persistent or associated with swelling or breathing difficulty. A clinician can help distinguish irritation from allergy, heat rash or another cause.
A lower-impact laundry routine
A first wash does not need to become an intensive treatment. Wash full loads, use concentrated detergent at the labelled dose, choose a suitable cool cycle and line-dry when practical. Hello Charlie’s Laundry collection groups current options without linking to a short-lived individual product page.
