How to Treat Stains on Cloth Diapers: A Parent’s Guide to Keeping Your Diapers Bright

Posted on by sacred7senses

Cloth diapers are a wonderful eco-friendly and budget-conscious choice, but let’s face it—stains happen. Whether it’s from newborn poo, baby food blowouts, or overnight use, those lingering marks can be frustrating. The good news? Most stains are treatable and won’t affect the diaper’s performance. Here’s how to safely and effectively treat stains on cloth diapers, and even prevent them from happening in the first place.

Why Do Cloth Diapers Stain?

Cloth diapers are made from absorbent fabrics that naturally hold onto moisture—and sometimes, color. Here are the most common causes of staining:

  • Breastfed baby poop: Bright yellow and seedy, this type of poop is notorious for leaving behind stains.

  • Solid food transitions: Foods like blueberries, carrots, and sweet potatoes can change the color of stool.

  • Hard water: Mineral buildup can make it harder to remove waste.

  • Detergent build-up or ineffective washing routines.

Stain Treatment Options

1. Sun Bleaching (Nature’s Magic Eraser)

Sunshine is one of the best tools in your cloth diapering arsenal. Even on cloudy days, the UV rays help break down stains and whiten fabric.

How to do it:

  • Wash your diapers as usual.

  • Lay the damp, clean diapers flat in direct sunlight.

  • Leave them out for a few hours.

  • If needed, spritz with lemon juice before sunning for stubborn stains (optional, test first).

💡 Tip: Avoid sunning colors or PUL (the waterproof layer) for too long to prevent fading or damage.

2. Oxi Soak

Oxi-based cleaners (like OxiClean Baby or Free & Clear versions) help lift stains without harsh bleach.

How to use:

  • Dissolve 1 scoop of Oxi in a tub or bucket of warm water.

  • Soak stained inserts (not covers with PUL) for up to 6 hours.

  • Rinse thoroughly, then wash as normal.

⚠️ Avoid soaking overnight or using hot water on bamboo/hemp blends—over time, it can weaken natural fibers.

3. Hydrogen Peroxide Paste (Spot Treatment)

Hydrogen peroxide (3%) mixed with a bit of baking soda can help lift stubborn stains.

How to use:

  • Mix into a paste and apply directly to the stain.

  • Let sit for 30 minutes.

  • Wash as usual.

🚫 Don’t use this method frequently on natural fibers—it’s better for occasional use.

4. Laundry Sanitizers (Optional Add-Ins)

Products like Lysol Laundry Sanitizer or diluted bleach (properly measured) can help disinfect and reduce set-in stains.

For bleach sanitizing:

  • Use ¼ cup of bleach in a large load.

  • Wash on hot, rinse well.

⚠️ Don’t overuse bleach—it can break down elastic and fabric over time.

How to Prevent Diaper Stains

Prevention is key. Here’s how to minimize staining from the start:

  • Rinse solids promptly. Knock solids into the toilet or use a diaper sprayer.

  • Cold rinse before your wash cycle. Helps prevent poop proteins from setting.

  • Wash every 2–3 days. Letting diapers sit longer gives stains more time to set.

  • Use a strong detergent. Tide Powder is often recommended for cloth diapers because of its effective formula.

  • Avoid fabric softeners and dryer sheets. These coat fibers and trap stains.

Are Stains Harmful?

Nope! Stains may look unsightly, but they don’t affect the performance of your cloth diapers. They’re purely cosmetic. As long as your diapers are washed properly and don’t smell or repel, you’re good to go.

Final Thoughts

Stains are a normal part of the cloth diapering journey. With some sunlight, a good wash routine, and an occasional soak, you can keep your stash looking and performing its best. Don’t stress over every mark—your baby certainly won’t mind!
