Bleach baths (for eczema)
What are bleach baths?
Bleach baths are a simple and effective home treatment for many skin problems. They are especially helpful for eczema (atopic dermatitis) and itchy skin, but they can also speed healing of cuts, sores, open wounds, and superficial skin infections. A bleach bath helps calm irritation, reduce bacteria or yeast on the skin, and promote faster healing.
The active ingredient in bleach is sodium hypochlorite, a disinfectant that kills bacteria, yeast, and viruses. When added to warm bath water in the right amount, it turns the tub into a diluted, chlorinated bath—similar to a swimming pool.
Important: You MUST use household bleach that contains sodium hypochlorite. Do not use “chlorine-free” bleach, which is usually made with hydrogen peroxide and is not effective for bleach baths. Only a small amount of bleach should ever be added to a bathtub (see recipe below).

Recipe for Baby Bathtub
Add: 1 capful of bleach to warm water
Steps for making and taking bleach baths:
Prepare the recipe (see instructions above).
Soak in warm (not hot) water from the neck down for 10–20 minutes.
For infants or small children, you can use a smaller tub or basin.
Rinse off with fresh water if needed.
Pat the skin dry gently with a clean towel (do not rub).
Apply a thick moisturizer such as CeraVe cream or Vaseline to the entire body—especially on eczema patches or areas of broken skin.
Are bleach baths safe for my kids?
Yes. When diluted correctly, bleach baths are as safe as swimming in a chlorinated pool. You’re not bathing in straight bleach—you’re soaking in water with a very small amount added.
It’s also fine to dip a soft washcloth in the bathwater and gently wipe areas like the face if your child has eczema or dry skin there. Most children (and adults) find bleach baths soothing and helpful for reducing irritation.
How often do I do bleach baths?
Most people do bleach baths 2 times per week. If your skin improves and you find them soothing, they can be done daily.
The most important step is what you do after: always apply a generous layer of moisturizer (like CeraVe cream or Vaseline) right after the bath to lock in hydration and keep your skin barrier strong.
What if bleach baths are not helping?
Most people notice improvement, especially with eczema, but sometimes bleach baths aren’t enough on their own. Check my Eczema page for more options. If your skin still isn’t improving, see a board-certified dermatologist in your area. If you are in or near Utah, see one of my excellent colleagues at the University of Utah or me virtually with Honeydew.
