Study design
Study participants were each given a bottle of 8.25% concentrated Clorox® bleach with a measuring cup marked to 3-oz volume. Participants were instructed to dilute 3 oz of bleach in approximately 40 gallons of water (final concentration 0.005% NaClO in a standard bathtub) and bathe for 5–10 min, 2x/week for a total of 12 weeks. Subjects were evaluated at 3 different time points: baseline (before bleach baths), 6 and 12 weeks after bleach baths.
