๐Ÿ‘ถ Because Baby Skin is Precious! Know-How for Washing Baby/Infant Clothes to Minimize Skin Irritation and Remove Stains

Baby and infant clothes require more delicate care than adult clothes. A baby's skin is sensitive and has low immunity, making it vulnerable to stains and bacterial growth from detergent residue, fluorescent whitening agents, frequent spit-up, or diaper soiling. We share the know-how for safely washing infant clothes to protect the baby's health and care for the fabric.


๐Ÿ”‘ Core of Infant Clothes Washing: Safe Detergent, Sufficient Rinsing, Immediate Stain Treatment

The key is to protect the baby's skin from harmful substances during washing and not to leave stains unattended for long.

๐Ÿ’ก 3 Steps for Safe Washing of Baby/Infant Clothes

1. ๐Ÿงผ Selecting and Using a Safe Detergent:

  • Baby-Specific Detergent is Essential: Use a baby-specific detergent that minimizes chemical ingredients such as fluorescent whitening agents, artificial colors, and fragrances. General detergents have a high concentration of ingredients and are likely to leave residues on baby clothes.
  • Minimize Bleach Use: For stain removal, use a small amount of oxygen bleach (sodium percarbonate) instead of chlorine bleach, but reduce usage as much as possible. (Residues are a source of baby skin irritation.)
  • Utilize Baking Soda/Citric Acid: Use natural cleaning agents such as baking soda (cleaning/deodorizing) and citric acid (fabric softening effect and neutralization of residual alkaline components) along with the detergent.

2. ๐Ÿ’ฆ Immediate Pre-Washing for Stain Removal:

  • Immediate Stain Treatment: Immediately rinse and pre-wash contaminations such as breast milk, formula, baby food, spit-up, and urine/feces in running water before they set on the clothes.
    • Protein Stains (Milk/Spit-up): Rinse with cold water to prevent the protein from coagulating. Then rub with baby detergent or dish soap.
  • Utilize Boiling: White cotton clothes can be boiled once or twice a week to sterilize bacteria. (Caution: Be careful with color bleeding on colored clothes.)

3. ๐Ÿšฟ Sufficient Rinsing to Remove Detergent Residue:

  • Add Rinse Cycles: Add at least 1-2 more rinse cycles than the general washing course to completely remove detergent residue.
  • Drying After Spin: After washing and rinsing, dry well in the sun (UV sterilization effect) to prevent bacterial growth. When drying indoors, ensure good ventilation.

It is important to always wash infant clothes separately from adult clothes and to dry them completely after washing.
