Corrosion behind Draft Inducer Fan Housing?

Hello,

HVAC is a 30 year old Carrier Plus 90.

I'm trying to figure out what this Corrosion is behind the Draft Inducer Motor and fan where the vents on the HVAC are.

Is this where the CO vents out from the Natural Gas Heat Exchanger?

Should these vents be cleaned of this Corrosion (comes off easily), would be a PITA to take off that additional inducer housing since it's sealed with RTV.

I've already replaced the Circuit Board with a new one and have a new Inducer Motor ready to be installed.

Thanks for any suggestions
