Another point that's being over looked and its a major, the removal of the blower and cleaning of it.
If that's not being done, then complete cleaning is really lacking a major component. A dirty blower will just continue to spread contaminants. Not even a good air washing will remove the years of build crud off the fan blades.
Check into NADCA standards, they will recommend removal and cleaning as part of the "Source Removal System".
