Why Breast Milk stains are tricky

Protein stains contain amino acid chains that denature and coagulate above 40°C, permanently cross-linking with fabric fibers — which makes cold water the single most critical first step.

How to prevent Breast Milk stains

Rinse with cold water before the milk dries — dried breast milk bonds to fibre rapidly. Keep a damp cloth accessible during feeding. Enzyme detergent is highly effective on this protein-based stain.
