When I found OCF, I was having tremendous mucous problems and asked about mucositis only to find out that it had nothing to do with mucous, and instead meant mouth sores.   You can do a search here on OCF for mucositis for the threads, but basically most people used a baking soda rinse.  I used seltzer water which while it burned, worked on both the mucous and the mucositis.  Here is a link to the OCF main page on mucositis 
OCF Mucositis This has detailed information and info on drugs, rinses, etc that I hope will help you.
