My vet also recommended using any type of clear alcohol, such as vodka or gin. It doesn't seem to burn like Stridex and worked great on my cat. I just purchased one of the tiny airplane size bottles of vodka and used it with cotton balls.
I was cat sitting and my friends cat had some acne. Her vet gave me some
?pledjets that were basically stridex type pads.. Can't remember what the ingredients were but I wouldn't be surprised it it was the same thing.
