What You'll Learn
Ventilate the room
Ventilating the room is one of the most important steps to take when dealing with spray paint fumes. The Environmental Protection Agency (EPA) has stated that spray paint contains Volatile Organic Compounds (VOCs) which can be dangerous to human health. Therefore, it is imperative to ensure that the room is well-ventilated to avoid inhaling these toxic chemicals.
To ventilate the room effectively, open all windows and doors to create a constant airflow. This will allow fresh air to circulate and help disperse the spray paint fumes. If it is a particularly windy day, take advantage of the natural wind currents by positioning yourself upwind of the spray paint source, so that the wind blows the fumes away from you and out of the room.
In addition to opening windows and doors, the use of fans can further enhance ventilation. Place several rotating fans around the room, angled towards the open windows, to help extract the fumes and improve air circulation. However, it is important to note that fans should not be switched on until the paint is touch-dry, as per the manufacturer's instructions.
If the room you are painting has an air conditioning system, it is recommended to turn it off while painting and during the drying process. Running the air conditioner while spray painting can recirculate the fumes, spreading them throughout the house. Instead, opt for natural airflow or fans to improve ventilation.
Finally, be mindful of the time of year and the temperature outside when ventilating the room. If you are painting during winter, avoid turning on the heating until the paint is completely dry. Keeping the room cool will help to minimise the presence of fumes.

Use air purifiers
Spray paints are a convenient way to reinvent items or surfaces in your home. However, the chemicals in spray paint can quickly spread throughout the air, compromising indoor air quality and potentially causing health issues. The smell of spray paint can linger for weeks, and while air fresheners, scented candles, or essential oils can mask the odour, they do not eliminate it.
Air purifiers are an effective way to tackle paint odours, especially if ventilation alone isn't sufficient. They are specifically designed to deal with noxious chemicals, allergens, and odours. When choosing an air purifier, look for one with a HEPA filter, which can capture tiny airborne particles, including paint fumes. The HEPA filter uses a fine wave mesh to grab things like dust, dirt, and other particles that are harmful to your health. Additionally, an air purifier with an activated carbon or charcoal layer will help absorb gases and odours.
To use an air purifier to get rid of spray paint smell, position the purifier in the painted room and let it run continuously until the smell subsides. You can also use fans to improve air circulation, directing them towards windows and outdoor areas to speed up the process. It is important to maintain proper ventilation during and after painting, even while using an air purifier.
There are various air purifiers on the market that can effectively remove paint odours and VOCs. The EnviroKlenz Air System, for example, uses a hospital-grade HEPA filter and an effective earth mineral technology air cartridge. This two-stage filtration system can capture, contain, and neutralize noxious and toxic chemicals and odours from the air. Another option is the IP Systems air purifier, which uses an activated carbon base to help gas particles adhere to solid particles, removing them from the air and effectively eliminating odours.
In addition to using an air purifier, choosing the right type of paint can also help minimize odours. Low-VOC volatile organic compound spray paints emit fewer harmful chemicals and reduce the intensity and duration of paint odours. Water-based paints also tend to have lower VOC levels, making them safer to use. Checking the VOC content on the paint label or Safety Data Sheet (SDS) can help you make an informed decision.

Neutralise with onions
Onions contain a chemical that neutralises the chemicals that make the paint smell. All you need to do is chop an onion in half and place it in the room you’re painting. According to Dr. Le, it is likely that the thiols released from onions, rather than the tear-inducing propanethial-S-oxide, are reacting directly with aldehydes, which are the chemicals that cause the paint smell.
Dr. Le recommends using enough onions so that a regular person can smell them in the room before painting. Chop the onions and leave them for 30 to 60 minutes before painting. Make sure there are enough onions so that anyone can smell them in the room. However, it is important to note that chemically sensitive people may have a strong aversion to the smell of onions. Therefore, it is advised that sensitive individuals should not be in the room when the paint is wet.
While there is anecdotal evidence to support the use of onions for reducing paint smell, there is a lack of scientific studies directly examining their effectiveness. The results from surveys and real-life experiments have been mixed, and more research is needed to confirm the efficacy of onions in neutralising paint odours.
In addition to using onions, you can also try other natural odour absorbers such as baking soda, vinegar, or activated charcoal. These substances can be placed in bowls or sprinkled on affected surfaces to help eliminate paint odours. However, it is important to note that while vinegar can help neutralise odours, it does not address the presence of VOCs, which are the toxic chemicals released by paint.

Absorb with baking soda
Spray paint is a convenient way to reinvent items or surfaces in your home. However, the strong chemical composition of spray paint can result in an overpowering smell that lingers long after the item has dried. This is caused by the emission of volatile organic compounds (VOCs) into the air, which can have adverse health effects. To eliminate this issue, one effective method is to use baking soda, a natural odour absorber.
Baking soda, or sodium bicarbonate, is known for its ability to neutralise and absorb strong odours. When dealing with spray paint smell, simply place a bowl filled with baking soda in the affected room. For added convenience, you can also pour the baking soda onto plates and scatter them throughout the space. The baking soda will work its magic by absorbing the paint odour, leaving the room smelling fresh.
If you're concerned about soft furnishings like carpets or sofas that have been exposed to spray paint smell, baking soda can also be of great help. Sprinkle the baking soda generously over the affected areas, ensuring an even coverage. Leave it overnight, or for several hours, to allow the baking soda to absorb the paint odour and any associated chemicals. The next day, simply vacuum up the baking soda, and you'll notice a significant reduction in the spray paint smell.
In addition to its odour-absorbing properties, baking soda is a safe and natural alternative to harsh chemicals. It is non-toxic and gentle, making it ideal for use in your living space. By using baking soda, you can effectively eliminate spray paint smells without resorting to strong, potentially harmful substances.
By following these simple steps and harnessing the power of baking soda, you can effectively minimise the lingering spray paint smell on plastic items or in any enclosed space. Not only will this improve the indoor air quality, but it will also contribute to a healthier environment for you and your loved ones.

Store in cardboard boxes
If you are looking to store freshly spray-painted plastic items in cardboard boxes, it is important to note that the paint smell will be limited if the cardboard boxes are kept shut even when empty. The cardboard will absorb the trace chemicals that evaporate. To further reduce the smell, you can use a mixture of vinegar and water in a spray bottle and spritz it onto the cardboard boxes or wipe down the insides with a cloth soaked in the mixture.
When storing spray-painted items, it is important to consider the temperature and environment. The ideal temperature to store spray paint cans and freshly painted items is between 60 to 80 degrees Fahrenheit. Avoid storing them in freezing temperatures as this will rapidly degrade the paint and may cause the can to burst. Similarly, extreme heat can also cause the can to rupture, so do not store them in direct sunlight or near ignition sources, and keep them below 120 degrees Fahrenheit.
Additionally, it is recommended to keep spray-painted items and the paint cans themselves in a locked cabinet, away from children and flammable materials. A climate-controlled storage unit or a well-ventilated area of your home, such as a main floor storage closet, can be ideal for this purpose.
For long-term storage, it is crucial to properly prepare the spray paint cans to avoid clogging. After each use, turn the can upside down and spray for several seconds to clear the drip tube and nozzle. You can also remove the nozzle and store it in a small container of acetone, replacing it when you are ready to use the paint again.
