here is what I wrote down in my notes 
For baby clothes, the best stain removal method depends on whether you’re dealing with milk, formula, spit up, poop, food, or something oily. Here are some simple, baby friendly options to try:
Milk, formula & spit up stains
Simple pre-treatment:
• 1 cup warm water
• 1 teaspoon liquid laundry detergent
Apply the mixture directly to the stain or let the clothing soak for 15–30 minutes. Gently rub the fabric together, then wash as usual.
For breast milk specifically, rinse with cold water first because hot water can cause protein-based stains to set.
Poop stains
-
Rinse the stain under cold running water, preferably from the back of the fabric.
-
Apply a small amount of liquid laundry detergent directly to the stain.
-
Let it sit for 15–30 minutes.
-
Wash according to the clothing’s care instructions.
-
If a yellow stain remains, place the damp garment in the sunlight to help naturally lighten the stain.
Food stains
For carrots, sweet potatoes, berries, baby food, and similar stains:
• Rinse with cold water.
• Apply liquid laundry detergent directly to the stain.
• Let it sit for 15–30 minutes.
• Wash normally.
• Repeat if necessary.
Try not to put stained clothing in the dryer until the stain is completely gone because the heat can permanently set it.
Greasy or oily stains
For baby lotion, diaper cream, breast milk fat, and oily foods:
• Apply a few drops of liquid dish soap or laundry detergent directly to the stain.
• Gently work it into the fabric.
• Let it sit for 10–15 minutes.
• Rinse thoroughly.
• Wash normally.
For really stubborn stains
An oxygen-based laundry stain remover can be helpful for washable baby clothes, but always check the garment’s care label first. Avoid mixing different cleaning products together.
My favorite overall baby stain routine:
Cold-water rinse → liquid detergent directly on the stain → 15–30 minute soak → wash → air-dry and check → repeat if needed.
Bonus tip for stubborn yellow stains
Sunlight can be surprisingly effective on baby stains, especially poop and spit-up stains. After washing, leave the damp clothing in direct sunlight for a few hours. The natural UV light can help fade the remaining discoloration. Just be mindful with darker or brightly colored clothing, since prolonged sun exposure can cause fading.
Simple DIY stain paste
For a stubborn stain, you can make a simple paste using:
• 1 tablespoon baking soda
• Enough water to create a paste
Apply it to the stain, gently rub it in, and let it sit for about 15–30 minutes. Rinse well and wash normally.
Always spot test homemade mixtures on an inconspicuous area first, especially with colored or delicate fabrics.
