If you will not be eating the ears of corn within about 3 or 4 days, you might consider freezing the ears of corn to help retain its freshness. Before freezing, shuck the husks and remove the silky strings. Rinse the ears under cool running water.
Blanch the corn on the cob in boiling water for about 4 minutes followed by placing them into an ice bath to stop the cooking action. Place the ears in a single layer in a food quality Ziploc-type bag and put them into the freezer until needed.
