Scientists say that diluting bleach may be the key to reducing flare-ups and rashes caused by chronic eczema.

Pediatric patients were given baths with a small amount of bleach, which researchers at Feinberg School of Medicine said minimized the red, dry flaky skin commonly associated with the dermatological disorder.

The baths were given twice a week for three months, and the scientists said the five to 10 minute baths were effective enough that they stopped the study to administer the treatment to those on placebo.

"This study shows that simple household bleach, which we think decreases the staphylococcus on the skin, can help these children," said Dr Amy Paller.

Staph infections, which are present in more than two-thirds of eczema sufferers, are a concern because of anti-biotic resistant strains such as MRSA, and the researchers said they adapted a hospital sanitation technique to come up with the treatment.

Roughly 15 million Americans suffer from eczema, including up to one out of every five children, according to the National Institutes of Health.
