 Acetic acid is an effective antiseptic when used as a 1% solution, with broad spectrum of activity against streptococci, staphylococci, pseudomonas, enterococci and others.It may be used to treat skin infections caused by pseudomonas strains resistant to typical antibiotics.While diluted acetic acid is used in iontophoresis, no high quality evidence supports this treatment for rotator cuff disease.
