Doubt if that will 'clean' out Thomas.
Will need some serious restorative work by the looks of it.
If that is dark colour is 'wet' which is showing a false colour change, would need to see when dry as to how far the stain is.
If you have no training walk away, I am sure there are others on here who will advise, contact Judy Bass who would advise you.
Em Clean would be your first port of call to kill the bacteria and any smell that goes with it.
This may also remove some staining. Then Aniline Cleaner and Aniline Stain Remover followed by colour restoration if needed.
