I don't think the greying effect which really isn't there at the moment was due to a bleaching effect.
I tissue still has sores on them, I suppose I'm trying to see if they are canker sores are not. If they are do you still use mms?
I'm not sure what you mean by mms is a chemical and the lime juice is an acid, the lime juice I used is supposed to activate the solution I bought(not sure if that is what creates mms), I was just following the protocol given.
