It is later during the 20th century when it started being considered for eczema.  Bleach is harsh at full concentration but when diluted it can be used as a strong arsenal to treat both children and adults to control the symptoms, reduce eczema flare-ups as well as in fighting off bacteria encouraging eczema. Here is more on the use of bleach bath for eczema, whether it is safe and how to prepare a bleach bath for eczema.

It depends on the amount of water you want to use. For a ½ full tub of water use ¼ cup of bleach.

I personally cringed at the sound of intentionally adding bleach to bathwater. When you think of how harsh it has to be to strip of tough stains, putting it in the same sentence with delicate eczema skin doesn’t sound right. But I finally understand the reasoning behind this. Other than get rid of stains, at dilute concentrations, it effectively kills bacteria a common cause of itching in eczema. Bacteria will easily enter the broken skin and cause irritation which will in turn cause itching.

  1. Bleach baths for treating eczema can be very affective. The concentrate used is very low 0.005% bleach v water. It’s less than the chlorine level in a swimming pool. When most people ( Like i did ) hear the word BLEACH it scares the life out of you. And the thought of adding this to your already sensitive skin condition seem stupid. However, is is an effective way to control bacteria and reduce infections. I have tried it with myself and both my children.
