Old plastic toolboxes can develop a putrid odour, often described as resembling vomit, due to the breakdown of the plastic and the release of butyric acid, a chemical also produced by the anaerobic fermentation that occurs in the human gut. This process can be accelerated by certain conditions, such as prolonged exposure to moisture or specific chemicals. Various methods have been suggested to alleviate this issue, including coating the toolbox's interior with a sealing agent, such as shellac, or using odour-absorbing materials like cat litter.

Plastic toolboxes can smell like vomit due to the breakdown of acetate
One of the chemicals produced during the degradation of acetate is butyric acid, which is also found in vomit. Butyric acid has a very potent and unpleasant odour, which can be challenging to eliminate. Some people have suggested sealing the affected tools or tool handles with a coating, such as shellac, clear lacquer, or polyurethane, to contain the odour. Others have recommended drilling small holes in the toolbox to allow the gas to escape.
The smell of vomit from degrading acetate is not limited to toolboxes and has also been observed in other plastic products, such as fishing tackle boxes and pinball replacement plastics. In some cases, the odour may be strong enough to cause nausea. While sealing or coating the plastic can help contain the smell, it may not always be effective, and replacing the affected items with non-plastic alternatives may be the best solution.
Additionally, the breakdown of acetate in plastic toolboxes can be influenced by the storage conditions. For example, storing a toolbox in a damp, cold garage may accelerate the degradation process, leading to a more pronounced odour. Prolonged exposure to certain chemicals or lubricants used on tools can also contribute to the development of unpleasant smells.
To prevent or mitigate the smell of vomit from plastic toolboxes, it is essential to consider the materials used in the tools and the storage conditions. Choosing tools with alternative handle materials, such as wood, or opting for toolboxes made from different materials, can help avoid the issue of degrading acetate. Proper ventilation and regular cleaning of the toolbox and its contents may also help reduce the buildup of unpleasant odours.

The smell can be caused by lubricants and sprays reacting with plastic
Plastic toolboxes can develop a foul odour over time due to various factors, and one possible cause is the reaction between lubricants and sprays with the plastic material. This occurs when lubricants and sprays used to prevent rust on tools come into contact with the plastic surfaces of the toolbox, resulting in the creation of an unpleasant smell.
The smell can be attributed to the chemical interaction between the lubricants, sprays, and the plastic composition. Certain chemicals present in these substances can react with each other, leading to the formation of odorous compounds. The type of plastic used in the toolbox construction may also play a role in the development of the odour. Different types of plastics have varying chemical structures and properties, which can influence their reaction with the lubricants and sprays.
Additionally, the age and condition of the plastic toolbox can be a contributing factor. Older plastic toolboxes may have undergone degradation or breakdown of the plastic material over time, making them more susceptible to reacting with the chemicals in the lubricants and sprays. Environmental factors, such as temperature and humidity, can also affect the rate and severity of the reaction, impacting the intensity of the odour.
Furthermore, the type and quality of lubricants and sprays used can vary, and some may contain stronger or more reactive chemicals than others. This variation can result in different levels of odour development when they come into contact with the plastic surfaces. In some cases, the reaction may be accelerated or more pronounced if the lubricants or sprays are not properly applied or if excessive amounts are used.
To mitigate this issue, it is essential to choose lubricants and sprays that are suitable for use with plastic tools and toolboxes. Reading product labels and instructions carefully can help identify products that are less likely to react with plastic materials. Additionally, proper ventilation and storage conditions can help minimise the intensity of the odour by allowing any gases or odours to dissipate instead of becoming trapped within the toolbox.

The odour can be locked in by food stains
Plastic tool boxes can start to smell due to the breakdown of certain plastics and adhesives over time. This can be accelerated by specific conditions, such as storing the toolbox in a damp, cold environment.
Food stains can also contribute to the odour in plastic tool boxes. Plastic is a porous material, which means it can absorb and lock in food smells, especially if the box is not cleaned or dried properly. Food residue, moisture, and scratches on the plastic surface create an ideal environment for bacteria, mould, or mildew, leading to musty odours. Oily foods can further exacerbate this issue by seeping into the plastic and trapping food particles, intensifying stains and odours.
To prevent food odours from becoming locked in, it is essential to clean and dry plastic tool boxes thoroughly after each use. Using a non-abrasive sponge or brush can help avoid scratches that can trap food particles and odours. Completely drying the toolbox before storing it is crucial to prevent moisture buildup, which can lead to unpleasant smells.
If your plastic toolbox already has a locked-in odour due to food stains, there are a few solutions you can try. One method is to wash the box with soap and water, then fill it with warm water and add baking soda, letting it soak for several hours or overnight before rinsing. Alternatively, you can create a baking soda paste, apply it to the interior, wait for some time, and then rinse. Exposing the toolbox to direct sunlight for one to two days can also help eliminate odours by breaking down the compounds causing the smell.

The toolbox's storage location may be a factor
Additionally, the type of plastic used in the toolbox's construction may be more susceptible to absorbing and retaining odours from its surroundings. Some plastics are known to break down over time and under specific conditions, releasing unpleasant odours.
Furthermore, the presence of certain lubricants and sprays used to prevent rust on tools can mix with the plastic of the toolbox, creating a persistent odour. This is supported by a user's comment on a forum who noted that after cleaning their toolbox, the odour returned, likely due to the interaction between the cleaning products and the plastic.
To mitigate these issues, it is recommended to store toolboxes in dry and well-ventilated areas, away from potential sources of odours. Additionally, when cleaning toolboxes, it is advisable to use mild, odourless, or natural cleaning agents to avoid potential chemical reactions with the plastic that could create unpleasant smells.

The smell can be mitigated with coatings or counteracting fragrances
The smell of old plastic toolboxes can be mitigated with coatings or counteracting fragrances. One user suggested using a spray epoxy, but noted that it would react with acetone. Another user recommended a product called "Plastic-Dip," which is a latex-based product that forms a rubberized handle on the tool. If you have a latex allergy, however, you should try something else.
Another user suggested coating the toolbox handles with shellac, a natural sealer, and found that it eliminated the odour. Other users recommended using a clear coating, such as clear acrylic, clear lacquer, or polyurethane, to seal in the odour. One user suggested using masking tape and MINIWAX fast-drying polyurethane gloss to lock in the odour.
In terms of counteracting fragrances, one user suggested adding a counteracting fragrance to plastic screwdriver handles, although they did not specify what type of fragrance to use. Another user recommended placing the toolbox in direct sunlight for one to two days, as sunlight can naturally eliminate odours by breaking down the compounds that cause them.
Other methods for removing odours from plastic containers include using baking soda, lemon juice, vinegar, or activated charcoal. These methods typically involve filling the container with warm water and the chosen substance, allowing it to soak for several hours or overnight, and then rinsing thoroughly with clean water. These methods can also be adapted for use with tools by placing them in a container with the chosen substance.
