Hi there FecalOdor,
Surfer27 here. I did come across something on the Internet, that may help you, with your problems!! It's a product, called: Pure Ayre Odor Eliminator. Apparently, as I have looked on the website, it's suppose to help clear any odors a person may come into contact with. It's also got a separate page, for those who may have TMAU also. It's also suppose to help suppress any tmau odors a person may have. I just wanted to pass this information onto you, as I have been going through exactly what you are going through. The website, is at: http://www.pureayre.com.
Check out all the information on this page, so you have an idea, as to what this odor eliminator spray eliminates. Hope that this helps. Take care. God bless.
