We thank you for your question. There is only very limited research on the topic of use of acetic acid at the exit site for a PD catheter exit-site infection (ESI) with Pseudomonas. The most recent recommendation from authors of the ISPD guidelines on this topic is:
 
“Acetic acid (vinegar) has been used as a wound antiseptic and has been recommended for treatment of Pseudomonas wounds infections. However, the experience of acetic acid for the treatment of ESI in PD patients is limited.” (1, page 147).
 
Out of interest, one of the members of our small ISPD Nurse Committee has used this strategy with success, the others have not used it.
