Will spraying clean evap into the cabin air filter slot help

Customer Question

Will spraying clean evap into the cabin air filter slot help to clean the evaporator core?

The spray-clean will only clean the "outside" of the evaporator. This spray is used for smell caused by condensation that does not drain properly and sits and turns moldy/musty. It is for smell only. It will not help the circulation of the refrigerant and make the system colder. When the evaporator is clogged, this is internal. No spray can cure that.
