Makeup Artists How to disinfect their brushes MAC counter or any other section of cosmetics?

I asked the girl what solution was made of it and could not tell me. What are ways to disinfect these tools if the tools to share with others?

Well …. MAC uses MAC brush cleaner. Other makeup counters could use their brush cleaner. Any accountant who sells brushes sells more paintbrush clean. I brush cleaner from MAC and I just saw the box and does not say what is in it.
