Fabric Seats, Carpets, and Floor Mats

Steam cleaning is ideal for deeply embedded smells.

Hard Surfaces (Dashboard, Console, Doors)

• Wipe down with an all-purpose automotive cleaner or degreaser
  
• Nicotine can form a yellowish film especially on plastic and vinyl
  

Replace the Cabin Air Filter

• A new cabin filter helps freshen airflow through the HVAC system
  

🔧 Pro Tip: If your vehicle was exposed to heavy smoke over time, replacing the cabin filter is non-negotiable.

Natural Remedies

• Baking Soda: Sprinkle on carpets and seats, let sit overnight, then vacuum

• Activated Charcoal: Highly effective in absorbing airborne smoke molecules
  

Commercial Odor Eliminators

• Use sprays like Ozium, Meguiar’s Whole Car Air Refresher, or Chemical Guys Odor Eliminator
  
• Spray into air vents and onto fabrics for deep penetration
  

Use an Ozone Generator (with Caution)

Step 4: Clean the HVAC System Thoroughly

Spray Odor Neutralizer Into Air Vents

• With the AC running in recirculate mode, spray a cleaner into the outside air intake (typically under the hood near the windshield)
  

Use an Interior Fogger or Vent Cleaner

• These are designed to circulate through the ducts
  
• They sanitize and neutralize odors where sprays can’t reach
  

Replace the Cabin Filter (if not already done)

This is often where lingering smoke odor hides even after cleaning the rest of the car.

Step 5: Air Out the Vehicle Completely

Open Doors and Windows

• Let the car breathe for several hours post-cleaning
  
• Choose a sunny day and park in a well-ventilated area
  

Use Fans to Circulate Fresh Air

Repeat cleaning steps if odor persists some smoke odors require multiple treatments.
