Breastmilk stains fabric because of its unique composition, which includes:

•Proteins – These can bind to fabric fibers, especially if exposed to heat, causing stubborn stains
•Fats – Milk fat can leave greasy or yellowish marks, especially over time
•Sugars (Lactose) – While not the main culprit, sugars can contribute to staining and even attract bacteria, which can worsen discoloration

The biggest issue with breastmilk stains is that they change over time—fresh stains might look like simple wet spots, but as they dry and oxidize, the proteins and fats can yellow, especially if exposed to heat (like from a dryer). That’s why cold water rinsing, pre-treating, and sunning are so effective—they break down the stain before it sets!

If you catch it early, you’re in luck! Here’s what to do:
1. Cold Water Rinse – Always start with a cold water rinse. Hot water can “cook” the proteins into the fabric, making the stain worse
2. Mild Soap or Baby Detergent – Rub a little liquid soap (like castile soap or your baby’s detergent) into the stain and let it sit for 5–10 minutes
3. Rinse Again & Wash – Toss it in the wash with cold or warm water (but not hot!) and your regular detergent
4. Check Before Drying – Heat from the dryer can set stains, so make sure it’s fully gone before tossing it in.

The Magic of the Sun ☀️

This is the easiest, most natural way to get breastmilk stains out!
•Sunlight naturally bleaches stains—no harsh chemicals needed
• Don’t dry the washed clothes in the dryer! Simply lay the damp fabric in direct sunlight for a few hours. Stains will fade like magic
•This works even on cloudy days, though it may take longer
•Bonus: Sunlight also kills bacteria, which is great for cloth diapers and burp cloths!

Preventing Breastmilk Stains
•Wear breast pads (disposables or washable ones) to catch leaks
•Rinse spills ASAP—even just a quick splash of water helps
