Let me share with you how I keep my car interior clean. Begin from top down, so that particles that are dislodged and fall during cleaning can be picked up later when you vacuum the seats and carpets. Remove the floor mats and vacuum and clean them separately.
Use the dusting brush to vacuum plastic, hard vinyl, and metal parts such as vanity mirror and dashboard components. Use the floor brush when vacuuming the carpet. Move the seats forward and backwards to reach areas under the seat. To avoid this problem entirely, make it known that no one can eat in your vehicle.
When it comes to beverages, only allow drinks that can be resealed when passengers aren’t drinking. For parents, if on a road trip, leave time to pull over and eat meals at highway rest stops rather than eating in the car to save time.
I have always wondered why did I not buy a car that had a built in vacuum?
