Sup guys. I know this may be a dumb question. But how did you guys clean up the inside of the plenum?

Remove the plenum and get you a can of brake cleaner. Make sure you remove the sensor located on the bottom of the plenum before you get started. Brake cleaner will clean it right up. Make sure you wear some eye protection. You might want to go ahead and get an upper intake gasket kit. The gaskets will very likely come apart when you remove the plenum.
