That "white build up " is thermal transfer grease and is supposed to be there. It helps to cool the module while still alowing an elecrical connection. If you dont put some on the module and plate you will be replacing the module soon.
Dont use lithium graese, get the proper grease from the parts store or a Radio Shack, either should have it. It usually comes in a little syringe type applicator.
