    The easiest way to remove old stains from baby clothing! Treat several items at once, even set in stains! Works for blowouts, spit-up stains, and yellow stains in baby clothing (from breast milk and formula stains) that have been in storage.

    Have you ever pulled out a box of stored infant clothes only to notice that they are STAINED? They were clean when you packed them away, but now they have yellow spots all over them. Well, those yellow spots are enzymes from spit-up and diaper blowouts. Bleach can help if the items are white, but what about colored outfits?

    I have the solution and have used this trick for years and years. Passed down from my sister's mother-in-law, this method for removing baby stains from laundry WORKS and is a tried and true method.

    Why This Method Works

    • Can be used on colored clothing. Bleach might work well for whites, but this method works for colored clothing and white clothing.
    • Works for yellow spots and stains. The yellow spots that linger in baby clothes are unique to baby stains. Oftentimes, baby clothes are clean when boxed and put into storage. The yellow stains show up later and are a not-so-fun surprise when you open the box years later. This method will get those stains out, when nothing else will.
    • Works for set in stains. Formula stains, spit-up stains, blowout stains, this will get all of those out. When your baby has a blowout, you aren't always able to rinse the item of clothing right away, especially if it happens in the car or on a trip! No worries, that cute little outfit can be saved.
    • No need to wash right away. If you don't want to treat items one at a time, you can give them a quick rinse, then set them to the side and wait until you have a few items with baby stains to treat together.

    What Other People Are Saying

    Okay honestly I was skeptical, but this worked PERFECTLY on year old formula, milk and blowout stains!!! I was worried about the little graphics melting or distorting but they are fine! THANK YOU for sharing this, I am now on a mission to obliterate all the stains from all of my little’s outgrown (and current 😅) clothes! 😂---Stephanie

    I am so glad I found this. I tried your method on baby clothes that had been stored in the attic for 25 years. It did an amazing job and now I can pass on some baby clothes to my daughter. Thank you for this wonderful method!---Kim

    Used your method on baby clothes that I had stored for more than 27 years, and I'm now handing them on to my son and his wife for my first grandchild. It worked perfectly - thanks so much for the tip.---Wendy

    Tips and Tricks

    1. Use boiling water. This literally goes against everything I was told about removing stains, but trust me, with this method, it works. The secret is Oxi Clean and BOILING water. Normally, you would use cold water and avoid hot water when trying to remove a stain, but not for baby stains using this method. The Oxi Clean has a chemical reaction with the enzymes in the spit up for those yellow stains (protein stains) that appear in baby clothing after sitting in storage.
    2. Repeat the process, if necessary. I've never had to do this, but if the formula or spit-up stain doesn't come out the first time around, you can simply repeat the steps and wash again.
    3. Treat light-colored clothing separately from dark-colored clothing to avoid color bleeding. As always, sort your clothing by whites and colors. This is a basic step for doing laundry, but some might be tempted to skip it and treat all stained clothing together.
    4. Pour Oxi Clean slowly into the water to avoid foaming over. Don't ask me how I know.

    Treating Yellow Stains In Baby Clothes

    We've all seen them. These stains can show up AFTER you wash the clothing, oftentimes they are the ones you see if you pull clothing out of the closet months or years later.

    I call these types of stains ‘baby stains’ because they are different than food or permanent marker type stains. Formula stains, breastmilk stains; they are caused by protein enzymes. Simply treating them with a spray-on stain remover is not going to work. You’re going to need an enzyme cleaner like OxiClean and a few additional steps.

    Treating Baby Blowout Stains In Baby Clothes

    Not only does this method treat old baby stains, but it can treat new stains too. My most recent experience was last night while I was at a meeting. Not only did his outfit take a hit, but also the blanket he was wrapped in, and the blanket that I laid him on while cleaning up the mess!

    I wasn't worried about baby stains at all. I simply wrapped it all up in a blanket and put it in the car and would eventually take care of it when I had time at home.

    Ingredients and Supplies

    • Oxiclean: Nothing fancy, just the original powdered formula.
    • Stock pot: You'll need a large stock pot, even to wash one item. The Oxiclean will react with the water and foam up, so a big pot works great for containing the foam.
    • Boiling water: Yep, boiling water! Trust the process.

    How to Remove Old Stains From Baby Clothing

    Pot of boiling water on stove.

    Step 1: Fill a large stock pot halfway with water and bring to a boil. Remove from heat.

    Step 2: SLOWLY pour ½ of a large scoop or 2 small scoops of Oxi Clean into the water (Scoop sizes vary, but about ¼ c. works great). The water will foam up, which is why it is important to only fill the pot halfway and to turn the heat off the burner.

    Step 3: Add stained clothing. Stir to make sure everything is soaked. Let soak for 10-15 minutes.

    Step 4: Dump the entire pot (excess water and all) into the washing machine. Run a normal cycle in the washing machine with a bit of laundry detergent. Place in the dryer and dry as usual.

    Note

    I've tried skipping this method and rinsing the fabrics with a variety of pretreatments like Spray and Wash, but I still sometimes end up with light yellow staining. So don't waste your money on pretreatments. Just start a pile of rinsed and stained baby clothing and treat them all at the same time.

    Stained Baby Clothing FAQs

    Why do baby clothes in storage have yellow stains?

    Yellow spots from formula or breastmilk spit-up stains can form on baby clothing over time. The protein enzymes from the milk stay in the clothing. Fresh spots may appear to have been removed from the clothing item during the wash, but over time they can reappear and show up as yellow spots. This is why you sometimes open a box of older baby clothes and find yellow spots on them that weren't there before.

    Do you need to pre-treat diaper blowout stains?

    For this method, no. If you have access to water, rinse the item, then set it aside until you are able to soak the item in boiling water and Oxiclean. If you don't have access to water, simply put the soiled item in a bag and wait until you get home to give it a quick rinse. You can wait until you have a few items to treat if you'd like. This will save you money on Oxiclean.

    Do I have to use boiling water to remove yellow stains in baby clothing.

    For this method, yes. The OxiClean and boiling water work together to lift the protein enzymes out of the clothing. This won't happen if you soak in cold water. The item of baby clothing is already stained; you have nothing to lose if it doesn't, so go ahead and try it!
