Diesel fuel is a popular choice for degreasing engines and mechanical parts due to its effectiveness in cutting through heavy grease and carbon deposits. However, it leaves behind an oily residue, requiring additional solvents for removal. While diesel is inexpensive and easily accessible, concerns have been raised about its negative environmental and health impacts, with some regulatory bodies discouraging its use as a solvent due to safety risks and potential fines. As a result, safer alternatives, such as mineral spirits, are recommended to avoid the hazards associated with diesel.

What You'll Learn
Pros and cons of using diesel fuel as a degreaser
Pros of using diesel fuel as a degreaser
Diesel fuel is a good degreaser for cutting through thick grease and heavy oil deposits. It is also cheap and easily accessible. It is better for use on aluminium than some other degreasers. It can also prevent corrosion for a short period of time.
Cons of using diesel fuel as a degreaser
Diesel fuel is a combustible chemical with a low flashpoint, meaning it poses an explosive danger. It is defined as a Hazardous Chemical according to OSHA standards. It also poses several physical, health, and environmental dangers to individuals, communities, and wildlife. It leaves an oily residue that requires another solvent to clean off. This can be a problem if you are using it on bike chains, as the chain will rust quickly if you don't remove the residue and allow it to air dry. The smell of diesel fuel is also unpleasant.
There are several alternative degreasers available, including mineral spirits, kerosene, terpenes, and citrus-based products.

Safety concerns
While diesel fuel can act as a degreaser, there are several safety concerns associated with its use.
Flammability and Fire Hazards
One of the primary safety concerns with using diesel fuel as a degreaser is its flammability. Diesel fuel is a combustible chemical with a low flashpoint, which means it can easily ignite when exposed to an open flame or spark. This poses a significant risk, especially when using diesel fuel in closed spaces or near potential sources of ignition.
Health Risks
Prolonged exposure to diesel fumes can be harmful to human health. Inhaling the fumes can cause respiratory issues and other health problems. Additionally, diesel fuel can cause skin irritation, and its strong odour can be unpleasant and lingering.
Environmental Impact
Diesel fuel also has a negative environmental impact. Improper disposal of diesel fuel can lead to soil and water contamination. Many areas have strict regulations regarding the disposal of diesel fuel due to its hazardous nature.
Alternative Recommendations
It is generally recommended to use cleaning products specifically designed for degreasing tasks, as they are safer, more environmentally friendly, and often more effective. Commercial degreasers are formulated to tackle grime, oils, and greases on a variety of surfaces and may contain surfactants that enhance their cleaning performance.
Additionally, some users have suggested using alternative solvents like kerosene, which is less odorous, or mineral spirits, which are safer alternatives.

Environmental impact
Diesel fuel is refined from crude oil and produces many harmful emissions when burned. Diesel-fueled vehicles are a major source of harmful pollutants, such as ground-level ozone, which damages crops, trees, and other vegetation, and particulate matter. Diesel engines are also one of the largest contributors to environmental pollution problems worldwide.
To address the environmental impact of diesel fuel, the U.S. Environmental Protection Agency (EPA) has established standards for the sulfur content of diesel fuel and emissions from new diesel engines. These standards have led to the production of Ultra-Low-Sulfur Diesel (ULSD) fuel, which helps to reduce emissions in older engines. However, diesel fuel use still contributes to air pollution, as it will take a long time to replace older diesel engines with newer, cleaner ones.
The Diesel Emissions Reduction Act Program was created to promote diesel emission reductions and authorize appropriations for technologies that reduce emissions from existing diesel engines. The program provides funding for projects that implement control strategies and involve national, state, and local partners to reduce diesel emissions.
In addition to the environmental impact of diesel fuel use, there are also concerns about the use of diesel as a solvent or degreaser. Using diesel as a solvent can pose explosive dangers and negative health consequences. Improperly disposing of the byproduct produced by using diesel as a solvent can also contaminate nearby bodies of water and groundwater. Safer alternative agents and solvents, such as mineral spirits, are recommended instead of risking the hazards of using diesel as a degreaser.
Overall, the environmental impact of diesel fuel is significant, and efforts are being made to reduce diesel emissions and promote cleaner alternatives to protect human health and the environment.

Alternatives to diesel fuel
While diesel fuel is a good degreaser, it has several drawbacks, including safety and environmental concerns. Here are some alternatives to diesel fuel for degreasing:
- Kerosene: Kerosene is a cheaper alternative to diesel fuel and is less odorous. It is also less flammable than diesel fuel and can be purchased as deodorized kerosene from hardware and home stores. Kerosene is also known as #1 diesel fuel, while regular pump diesel is #2. It is important to note that kerosene is still a petroleum product and may have similar environmental concerns as diesel fuel.
- Mineral spirits: Also known as naphtha, white gas, and other names, mineral spirits have similar properties to diesel but with lower boiling points and volatility. They are a good alternative if you want a product that evaporates more easily than diesel.
- Commercially available degreasers: These are formulated to effectively remove grease and grime without leaving an oily residue. They provide a safer and more eco-friendly alternative to diesel fuel.
- Water-based cleaners: These cleaners use surfactants and emulsifiers to suspend oil and grease in the cleaning solution, allowing for easier removal. They are safer for the environment and can be a good alternative to diesel fuel.
- Biodegradable degreasers: These are safer and more environmentally friendly alternatives to traditional solvents. They are highly effective at removing oil and grease and are easier to dispose of responsibly.
- Other methods: Depending on the specific application, other methods such as parts washers, ultrasonic cleaning, or mechanical cleaning with brushes and hot water can be effective alternatives to diesel fuel.
When choosing an alternative to diesel fuel, it is important to consider factors such as the type of material being cleaned, the extent of the grease or grime, safety considerations, environmental impact, and the availability and cost of the cleaning method.

Removing diesel residue
While diesel fuel can be used as a degreaser, it is not recommended due to the health, safety, and environmental risks associated with its use. Diesel fuel is a combustible, hazardous chemical with a low flashpoint, which means it can easily ignite and cause fires or explosions. Its use can result in serious safety risks and fines for violations.
Additionally, diesel fuel can leave behind an oily residue that requires another solvent, such as acetone or kerosene, to remove. This residue can interfere with lubrication and may need to be scrubbed off, adding extra steps to the cleaning process.
Instead of using diesel fuel, there are safer alternative agents and solvents available, such as mineral spirits, that can effectively remove grease without the same level of risk. Commercial degreasers, such as Chante Clair, Citra-Solv, or Blakes degreaser, are also available and can be safer options. These products often come in handy spray bottles, making application easy and controlled.
If you choose to use diesel fuel as a degreaser, it is important to exercise extreme caution due to its hazardous nature. Always follow safety protocols, including using proper personal protective equipment and ensuring adequate ventilation to mitigate potential health risks. Additionally, be mindful of the proper disposal of any byproducts to avoid contaminating nearby water sources and groundwater.
