How often should you deep clean car interior?

The interior of your car should be thoroughly cleaned once a month, but you should also do everything in your power to clean surface dust and remove garbage from the vehicle regularly. Garbage can make your car smell bad and it's harder to get rid of odors. Some people recommend cleaning the interior of the car at least twice a year (deep cleaning). Others do it more often, once a month or a week, or every other day.

Newman suggests following the steps below approximately once a month, or as needed. If you have school pickups, shared rides and sports practices on the horizon, you may want to increase it to twice a month.
