How do I remove corrosion from a battery compartment in an air pump?

This is a fairly open battery compartment fitting 4 D batteries with room to spare. In two small spots there is some heavy corrosion. What can I do to remove this corrosion? Please answer SOON, i need the air pump tonight!!!
I have tried scraping and it won’t come out all the way

scrape it out, then burnish the contacts with a nail file.
Spray the contacts with a silicon lube to help prevent more corrosion.
