Our Story Begins . . .

I inherited a 2008 Ford Focus from a lady who was like a grandmother to our family. Hoarding was a problem for her. She filled her vehicle up to the windows with papers, shopping bags, clothing, etc. in every seat. She apparently had spilled milk or something in the front passenger seat. It had been sitting idle for an entire summer with the windows closed and temperatures exceeding 100 degrees. By late fall, when my wife and I opened the door, the stench was so bad it could knock you off your feet. The odor might be described as a dead animal, a skunk, and rotten eggs combined. Dead bugs and flies were found everywhere, including inside the air vents. Our eyes burned. My wife wore gloves and a mask to clear it. Once we removed all the trash and could begin some surface cleaning, the arduous task of removing the stench for good ended up taking about seven months. I used just about every method of cleaning and deodorizing that exists. Local friends and neighbors, church associates, and relatives were amazed, amused, and interested in this roaming lab experiment on wheels.

1. Clear Out the Junk

We inherited the car In November. It had sat idle at least an entire summer, loaded up to the windows with papers, plastic grocery sacks, clothes, uneaten fast food, etc. We opened the front and passenger doors to begin the cleaning. My wife and I nearly filled an apartment dumpster with trash bags full of unusable items. We cleared out the dead bugs. Even after these measures, there was still a terrible stench.

2. Disinfectant and Spray Deodorizer

We used disinfectant sprays like Lysol to clean the dash and seats. The goal was not necessarily to get it completely deodorized, just to make it suitable to drive. My wife wore an N-95 mask because of the stench. We used a generic spray deodorizer similar to Febreze but the odor persisted.

3. Use Vent Clips and Air Fresheners

I hung air fresheners from the rearview mirror and attached Febreze vent clips. These methods offered temporary help, often covering up the odor instead of eliminating it. Once we made more progress with additional cleaning methods, I returned to using vent clips as part of ongoing maintenance to keep the car smelling fresh. Febreze offers a variety of delightful scents. But for now, more odor elimination was needed.

4. Go to a Professional Car Detailer

A professional car detailer cleaned and shampooed every surface, inside and out of the vehicle. He used a spill-proof organic air freshener by California Scents available in Coronado Cherry. A single canister was placed under the seat. This had a light fresh smell but seemed to get a little overpowering over time. You can regulate the amount of scent by opening or closing the air holes as needed. It lasts up to 60 days. It seemed more like a cover-up than an odor eliminator but provided some delightful relief.

5. Use a Car Odor Bomb/Fogger

I deployed the Dakota Odor Bomb. It claims to be a one-time, permanent odor-eliminating fogger. You place it in the middle of the car and depress and lock the canister button in place while it sprays a fog until it completely empties. You are not to disturb the area, keeping the doors closed for at least two hours and then ventilating for 30 minutes. The smell was eliminated for a day or two, but then the odor returned. I was becoming puzzled by the persistence of the smell.

6. Use Ozone to Attack Odors

Oxidizers like ozone attack odors very effectively. Baking soda, peroxides, fresh air, and ozone react with and neutralize odors including skunk smell. Oxygen in the air that you breathe has a chemical formula of O2 while ozone has three oxygen atoms and the chemical formula O3. It is produced in electrical storms. You might smell its fragrance after a spring thunderstorm. The chemical formula reacts with and eliminates strong odors, especially cigarette smoke.

I took the vehicle to a local dry cleaner who placed an ozone machine in it for about 24 hours. While this vehicle had some traces of cigarette smoke, it was the rotten stench odor that needed to be removed. After treatment, the vehicle smelled like ozone, somewhat pungent, and somewhat like the smell after an electrical storm. I could smell a combination of the foul odor and the ozone together for a day or two. After about three days, the odor was still present. I was starting to conclude that the odor was deeply embedded into the seats.

7. Shampoo with Pet Deodorizer

I went to Petsakes and was recommended a product called OdorPro, a non-allergenic, non-toxic, not a perfume cover-up type of shampoo. I used it in conjunction with a small portable carpet shampoo machine called the SpotBot by Bissell. Its brushes are designed to fit over the size of a "pet accident." It automatically applies the soap and scrubs the spot. It has a timer and stops when complete. It works especially well on flat surfaces like the seats and floorboards. I shampooed the carpets, floor mats, and headliner. It smelled fresh for about a day but the odor returned.

8. Use a Syringe with Liquid Deodorizer

I identified that the front passenger seat seemed to have the strongest odor. I filled a 20 mL syringe with OdorPro liquid deodorizer from the pet store and injected it two inches into 10 areas of each seat, front and back. It provided some temporary improvements.

9. Remove Seats, Sprayed, and Wrapped in Plastic

This arduous deodorizing project carried into early spring. On a warm, sunny day, I removed both the passenger seat and driver's seat from the vehicle and placed them in the yard to air out. I sprayed them down with a whole can of Lysol spray deodorizer (about a half can for each seat) and wrapped them in a clear plastic bag in hopes that the deodorizer would penetrate deeply into the seats. After a couple of hours, I removed the plastic and re-installed them into the vehicle. It smelled fresh for about a day, but, you guessed it, the odor returned.

10. Completely Replace the Seats

I finally concluded that the seats needed to be replaced. I searched local salvage yards. I was able to replace the driver and rear bench seats but unfortunately not the passenger seat where I thought the odor originated. When I removed the rear seat, the odor from the bottom transferred to my hands; they reeked. the foam was completely saturated with the odor inside and out. Replacing the seats made a significant difference. Yet I could not find a replacement for the passenger seat, so it remained.

Fresh Air Over Time

In between all of these methods, I put down the windows and opened the trunk for several hours three to five days a week from the month of March through June. I realize not many people can do this during work hours because their car needs to be secured. I was able to keep an eye on my vehicle located outside my office window. Opening the car windows regularly seemed to diminish the last bit of odor in the passenger seat.

Tips and Pointers

We may never know the source of the odor, but it was industrial strength. Each of the methods improved the odor at least to some degree. The most significant measure I took was to replace the seats. I also believe that good old-fashioned fresh air made a significant difference. I would recommend that everyone regularly practice keeping the windows down, especially in cool dry weather. For ongoing maintenance, I might recommend the vent clips by Febreze, especially the ocean scent.

The car was handed down to our oldest daughters. I will never forget the day the oldest one said, “This car actually smells good!” I knew at that point it was mission accomplished.
