Key Reasons for Cloth Diaper Stink and Rash

• Improper washing routine:
  • Not using an approved detergent that targets human waste
  • Not using enough detergent, leading to unclean diapers
  • Using too much detergent, leading to residue buildup

• Washing Frequency:
  Not washing diapers frequently enough, or diapers that have been left in a sealed wet bag too long, will be more difficult to clean thoroughly and remove set-in waste and urine - also leading to the breakdown of elastics and waterproof laminate.

• Detergent buildup:

  Using the wrong type of detergent or not following the recommended amount can cause residue buildup.

• Ammonia production:

  When urine sits on a diaper for too long, the urea in it breaks down into ammonia, which can irritate the skin - looks similar to a red or pink sunburn.

• Not properly rinsing diapers:

  If the diapers aren't rinsed thoroughly, detergent residue can remain and irritate the skin. Over time this residue will buildup and cause stink.

The Impact of Too Much Detergent: Buildup Problems

Using excessive detergent might seem like the solution for squeaky-clean diapers, but it can actually lead to residue buildup on the fabric. This buildup can trap bacteria and ammonia, resulting in strong odors and potential skin irritation for your baby.

Signs of Detergent Buildup

• Visible suds or murky water: Perform a "swish test" to look for signs of buildup.
• Repelling issues: Diapers may repel liquid instead of absorbing it.
• Residue feel: A waxy, slimy, or sticky texture when the diapers are wet.
• Rashes: Bright red rashes, especially where the diaper touches the skin.

How to Fix Detergent Buildup

1. Strip the inserts: Use an approved stripping routine tailored for inserts.
2. Strip the diapers: Deep clean your diapers using a stripping method appropriate for the type of cloth diaper (e.g., pocket diapers, all-in-ones, prefolds).
3. Adjust your routine: Reevaluate your wash routine, including the detergent type and amount. Contact us for help creating a custom wash routine.

The Problem of Not Enough Detergent: Unclean Diapers

Under-washing your cloth diapers can leave behind bacteria, oils, and waste, leading to unpleasant odors and hygiene issues. If your diapers are not being cleaned properly, they can cause rashes and stink problems over time.

Signs of Unclean Diapers

• Barnyard smell: A musty, dirty smell that persists even after washing.
• Persistent odors: Smells that worsen with use or when diapers get wet.
• Frequent rashes: Red, irritated skin due to residual bacteria or waste.

How to Fix Unclean Diapers

1. Deep clean: Wash your diapers with the recommended amount of detergent on a hot wash cycle. Strip if necessary.
2. Sanitize if needed: For persistent issues, consider a bleach sanitizing routine. Note: bleach will not clean waste out of diapers or remove residue, bleach is only for disinfecting. 
3. Check your routine: Ensure your wash routine is thorough and includes appropriate detergent and rinse cycles.

How to Tell the Difference Between Buildup and Unclean Diapers

Tips for Preventing Odors, Stink, and Rashes

• Follow a consistent wash routine using the recommended detergent amount and a two wash routine.
• Rinse thoroughly to remove all detergent residue.
• For soft water, use slightly less detergent (e.g. med-large load with Tide: Hard water - "Line 3", Soft water - "Line 1"
• Avoid overloading the machine to allow for effective cleaning.
• Wash cloth diapers at max every 2-3 days.
• Dry properly to prevent mold or mildew growth.
