Bleach Baths for Eczema

Bleach baths can help some children (and adults!) with moderate to severe eczema by lowering skin bacteria and reducing infections that trigger flares.

Bleach Bath Recipe 🛁

(for unscented household bleach, 4–6% sodium hypochlorite)

  • Use regular, unscented household bleach only.
  • Do not use concentrated, “splash‑less,” thickened, or scented bleach.

Steps & Measurements 📋

  1. Fill the tub with lukewarm (not hot) water.
    • Full standard bathtub (about 40 gallons/150 L): add 1/2 cup (120 mL) bleach.
    • Half‑full tub: add 1/4 cup (60 mL) bleach.
    • Baby tub or small basin: add 1 teaspoon (5 mL) bleach per 1 gallon (3.8 L) of water.
  2. Swirl the water to mix well.
  3. Have your child soak from the neck down (or just the affected areas) for 5–10 minutes. Do not submerge the head or face. Close supervision at all times.
  4. Pat dry (don’t rub). Then moisturize the whole body generously within 3 minutes. (if prescribed apply medicated creams to inflamed areas first)
  5. Repeat 2–3 times per week, or as directed by your clinician.

Important Tips

If you’re unsure whether this is right for your child, check with your health care provider first.

  • Never apply undiluted bleach to skin.
  • Do not dunk the head or face.
  • Avoid mixing bleach with soaps, bath oils, or other cleaners.
  • Good ventilation helps.
  • If the skin stings or gets very irritated, end the bath, rinse, moisturize, and discuss with your clinician.
  • Lukewarm baths are best; hot water can worsen itching and dryness.
  • Moisturize at least twice daily and always after bathing; use soap‑free, fragrance‑free products.
  • Bleach may lighten fabrics; use old towels for drying.

When to Seek Medical Attention 🩺

Contact your healthcare provider if you see:

  • Signs of infection (yellow crust, pus, rapidly worsening redness)
