You would have known there was a problem the moment you touch the car's door handle. Having spent the day parked outside the city under the intense summer heat, by the time you manage to sit inside the vehicle, you get hit by that familiar smell that cannot be easily ignored. It is not simply the smell of hot air. There is definitely something foul-smelling going on here, and it is not about to dissipate by itself.

Chances are you've done something about it. Sprayed it with some deodorizer bought from a service station, cleaned up the insides thoroughly; but still, here we are, the same problem, same smell in the same car. You see, what you did only addressed the problem on the surface when in truth, the source of the smell is far beyond what those products can do; and it had been fueled daily by the heat outside. 

Ozone treatment will change all that.

Why Toronto's Summer Heat Intensifies Bad Car Odors

Does heat intensify the smell inside your car? Definitely, and the answer lies in basic principles.

Heat causes the molecules that emit an odor to react quickly and move swiftly. As temperatures rise, odor molecules become increasingly mobile and start filling every space inside your vehicle's cabin. On an average summer day in Toronto, a parked car's interior will quickly heat up to about 60 to 70°C when you leave the car. This temperature does not merely heat up a smell. It enhances it.

Throw in the humidity found during Toronto summers, and you get a smell that no longer simply resides in one place. Instead, it penetrates and infuses itself into every surface, from every seat, fabric upholstery, vent system, and interior seam of your vehicle.

The Most Common Sources of Bad Car Smells Toronto Drivers Deal With in Summer

The majority of foul smells within vehicles have a similar background story. Some substance found its way to the interior, there were hot summer months, and now the problem is much greater than its cause. 

Spills of any kind are one of the leading causes of unpleasant odors in cars. While it may seem like spilling a bit of coffee on the upholstery or leaving some take-out containers around won't be a huge deal, it becomes problematic during the summer months when it turns into an odor that will fill up your whole vehicle once you get into it.

Mold develops slowly. The wet umbrella placed on the doormat, the damp sports bag placed on the rear seat, the children entering with their clothes saturated by rain during summer. Water seeps into the carpet padding and seat cushions, and mold starts developing. Sweat resulting from lengthy journeys during rush hour on the Gardiner Expressway and Don Valley Parkway collects in the seat upholstery for the whole season. Cigarette smoke odor and wildfire smoke odor, which has become commonplace in Toronto during the summertime recently, permeates every cushion in the cabin interior.

How a Hot Closed Car Becomes a Breeding Ground for Bacteria and Mold

As soon as you get out of your car after locking it, there begins a battle between your vehicle’s interior and the external factors that you do not even realize.

Spores of bacteria which are produced from food leftovers, sweat and waste of animals begin to multiply rapidly and give off a pungent odor. The smell that you have been noticing since May didn’t magically come from outside and got inside of your car. It started to develop within it, and will continue developing every single hot day.

What Is Ozone Treatment and How Does It Work on Car Odors?

This treatment differs in principle from anything that you have attempted in your life before because the ozone treatment will do what other products could never achieve.

The ozone treatment starts with using an ozone generator designed by professionals. An ozone generator creates ozone, which consists of three oxygen atoms. After placing the machine into your car and letting it run for a certain period of time required by your car's needs, the ozone travels inside your car as a gas. It spreads throughout the cabin entering the ventilation system, passing through seat foam, entering carpet padding and getting to places that no liquid, no spray can ever get to.

Ozone is not masking the odors in any way possible. It is eliminating them at their molecular base. While other treatments were trying to hide odors, ozone is destroying them by means of molecular oxidation process. After this procedure is completed, all ozone will naturally revert to oxygen, leaving behind only neutral scent of fresh air.

Why Car Fresheners and DIY Methods Fall Short and Why Ozone Treatment Wins

Here is the critical issue that will determine why almost all of the above-mentioned solutions will not work. While air fresheners, enzyme sprays, baking soda, and even steam cleaning can be done superficially, ozone cleaning cannot. And that is why.

The simplest solution to a smelly home is to use air fresheners because they are cheap and easy. Their advantage is that they work for up to two days before the smell returns, sometimes stronger. This is because the bacteria or mold causing the odor continued to spread while your nose was being taken care of by the smell of perfume. Baking soda and enzyme sprays work better against odors and should definitely be used in case of minor accidents.

However, when summer heat turns an odor from superficial sources into something that has invaded your seat foam, carpets, and even the ventilation system of your vehicle, the smell gets into places that no air, liquid, and even steam cleaning can penetrate.

Because ozone cleaning uses gas rather than liquid, it works inside out and gets to the source of the odor right away.

How Long Does Ozone Treatment Last in a Car During Toronto's Hot Months?

2-3 months is how long the professional ozone treatment will last when you have an average level of odor present in your vehicle. This is the truth that few businesses want to tell you outright.

When dealing with severe issues such as persistent smoke odors, years of accumulated pet odor or widespread mold throughout the vehicle's vent system, a single treatment may not be enough. Here, a professional detail along with ozone treatment will deliver the most powerful and longest-lasting effect possible as the cleaning process eliminates the largest amount of contaminants before the ozone begins its work.

The best advice for maintaining any treatment throughout the hot Toronto summer is to get rid of all food waste the same day and keep wet things out of the car's interior completely. Moisture and heat are the driving factors behind most problems with odors. Eliminate these and enjoy your treatment longer.

Is Ozone Treatment Safe for Your Car's Interior and Your Family?

High amounts of ozone are not suitable for breathing, and this fact creates a reasonable doubt in many. However, once you know how professional ozone treatment is conducted, you will not have any doubt anymore.

The procedure takes place within an enclosed environment without the presence of anybody inside the vehicle. It means that neither people, children, nor animals get into contact with ozone during treatment. After the treatment is completed, the ventilation system removes ozone, which then turns into regular oxygen. As soon as you get your car keys, your car becomes a perfectly safe and clean place.

There is no trace left by ozone. No toxic gas stays there. Neither does any material become damaged during treatment. The change happens due to the elimination of the bacteria that caused the bad smell.

When Is the Right Time to Book an Ozone Treatment in Toronto?

Now is the time because soon another Toronto summer week will make the task all the more difficult to accomplish.

A foul or musty odor that immediately strikes upon entering the vehicle lets you know that bacteria or mold has settled deep inside the car's cabin. Odors from pets that resist even multiple cleansings tell you the odor source has gone beyond superficial cleaning to settle deep within the vehicle. An odor of smoke that can be detected even weeks after smoking cigarettes tells you it has soaked deep into the interior surfaces of the foam and upholstery. Foul-smelling air being blown from the vents means that mold has managed to penetrate the vehicle's air conditioning system.

All of these scenarios are telling you the same thing. If not now, then you can be sure the situation will become worse and require more labor and effort to clean up. Delaying past August will turn what could have been a single cleanup process into something that requires two visits.

What to Expect From ALPHASHINE's Professional Ozone Treatment Service in Toronto

Unlike any other service, ALPHASHINE does not conduct the same process on all automobiles that arrive. This begins with a proper evaluation of your exact odor case in order to ensure that the approach used will be suited to your specific needs in terms of duration, intensity, and possibly additional advice regarding future prevention.

The ozone generator is applied directly to your vehicle for however long your automobile requires it. Once the process is complete, your car will be entirely ventilated and will leave the premises smelling fresh rather than having its odor temporarily covered.

Drivers in Toronto choose ALPHASHINE due to their lasting results. If you’re tired of purchasing temporary relief with products that only work for a few days until the smell reappears, then do not settle for temporary solutions to a permanent problem. Your vehicle deserves better than to smell as though there is still a problem remaining to be solved. Contact ALPHASHINE now to get your free consultation.

Frequently Asked Questions

  1. Does heat make the odor in cars stronger?

    Absolutely. Heat causes odorous molecules to speed up and makes it easier for bacteria and molds to grow. In Toronto summers, a car can reach a temperature above 60 degrees Celsius in no time, even when parked. This makes it impossible for the smell to be tolerable.

  2. How long does ozone treatment take?

    Ozone treatment takes between an hour and two hours. Your ALPHASHINE professional will provide an accurate estimation depending on the vehicle and odor intensity once scheduled for the service.

  3. How long does a fresh odor last after ozone treatment?

    For moderate odors, it is realistic to expect two to three months. Not putting food waste or anything wet in the car prolongs this period.

  4. Is ozone treatment effective in eliminating odors resulting from smoke?

    Yes, ozone treatment works perfectly for smoke and is the best method for doing so. It reaches every surface of the car interior on a molecular level, places that sprays or cleaners do not get to.

  5. Is ozone treatment safe for children and animals after the treatment?

    Yes. As soon as the ventilation process is completed, the ozone reverts to normal oxygen without leaving anything dangerous behind. It becomes perfectly safe for anyone inside the car.
