I believe it's the carbonated water that cuts the salt and grease. I used to drink a lot of soda and switched to carbonated water so I understand what you mean by lubricant. My wife has a similar autoimmune problem. She also drinks 4-5 diet cokes a day. I wonder if there is a connection. There are flora in your mouth too.
