5. Clean Your Car
Go ahead, drop the napkins and rubber packs under your seat. Release the receipts from your last business-related drive in the glove box. A few days after your trip, when new fast-food wrappers join the old rubber wrappers.
When the glove box starts to become crowded with hotel vouchers and local maps when dog hair sticks to your luggage and gear, during the journey, take time every few days to clean your car of unwanted debris.
