In addition to antibiotics, whirlpool therapy can be used to treat erythrodermic flares of MF/SS because it reduces bacterial colonization and debrides excess scale. 5 It also decreases inflammation and promotes wound cleansing. 6 Moreover, a pilot study showed that whirlpool therapy followed by a quick rinse eradicated more than four times as many bacteria compared with whirlpool therapy alone. 7 In our protocol, the 0.25% acetic acid rinse further decreases the skin bacterial load and reduces skin pH, which inhibits S. aureus colonization.
