While diesel fuel is not considered to be particularly toxic, it can still be harmful to human health. Short-term exposure can irritate the eyes, nose, throat, and lungs, causing coughing, bronchitis, headaches, lightheadedness, and nausea. Lengthy exposure to diesel exhaust may increase the risk of developing asthma, lung disease, heart disease, and brain and immune system issues. Diesel has been used for decades as a parts cleaner, and some people still use it to remove grease and oil from engines. However, there are now many alternative degreasers available, such as terpenes, citrus-based products, and commercial degreasers, which are safer and more effective.

What You'll Learn
Diesel is an effective degreaser
Diesel has been used for many years as a degreaser, with some forum users recalling their fathers and grandfathers using it to clean car parts. It is also known as No. 2 fuel oil and is a fractional distillate of petroleum fuel oil.
However, diesel can leave a residue that may need to be removed with another solvent like acetone. It can also be expensive to use for this purpose. There are other degreasers available that are more cost-effective and specifically designed for cleaning parts, such as terpenes, citrus-based products, and commercial degreasers.
While diesel is not considered highly toxic, it can still have negative health effects. Short-term exposure can irritate the eyes, nose, throat, and lungs, causing coughing, bronchitis, headaches, lightheadedness, and nausea. Long-term exposure to diesel exhaust may increase the risk of asthma, lung disease, heart disease, and issues with the brain and immune system. Therefore, it is important to take safety precautions when using diesel as a degreaser, such as wearing gloves and a dust mask.

Health and safety concerns
While diesel fuel is not considered particularly toxic, and accidental poisoning is rare, it does pose several health and safety concerns.
Short-term exposure to diesel can irritate the eyes, nose, throat, and lungs, causing coughing, bronchitis, headaches, lightheadedness, and nausea. It is important to avoid long-term skin exposure to diesel, as this can result in eczema (dermatitis). Diesel should never be used to clean the skin and hair, as this practice has been linked to serious kidney damage. In addition, exposure to diesel exhaust over an extended period can increase the risk of developing asthma, various lung diseases, heart disease, and issues with the brain and immune system.
When using diesel as a solvent, it is crucial to take safety precautions. This includes wearing nitrile gloves to prevent skin contact and using fans to mitigate the effects of fumes. However, even with these measures in place, there is still a risk of exposure to harmful fumes.
There are alternative degreasers available that are less harmful to health. These include commercial degreasers, terpenes, and citrus-based products. Additionally, some people have recommended using white spirit, kerosene, or acetone as alternatives to diesel. While these alternatives may be less convenient or more expensive, they can significantly reduce the health risks associated with diesel fuel exposure.
It is also important to properly dispose of diesel fuel and any cleaning solutions containing diesel. Pouring diesel down the drain can contaminate water systems and harm the environment. Instead, absorb the diesel with cat litter and then dispose of it in an appropriate manner.

Alternative degreasers
While diesel fuel can be used to clean greasy car parts, it is not recommended due to potential health and safety hazards. Instead, there are several alternative degreasers that can be used to effectively remove grease and grime. These include:
- Commercial degreasers: There are a variety of commercial degreasers available that can be purchased from motor factors. These degreasers are designed to remove grease and grime from car parts and are similar to diesel in terms of viscosity and smell. They are also water-soluble, making them easier to dispose of compared to diesel.
- Terpenes and citrus-based products: Natural products such as terpenes and citrus-based degreasers are effective alternatives to diesel. Citra-solv, for example, can be used on bicycle chains followed by a water rinse and lubrication.
- Krud Kutter: This degreaser is U.S. EPA Safer Choice certified, ensuring that it is safer for human health and the environment. It effectively removes grease and stubborn residues.
- Easy-Off: This foaming spray degreaser is affordable and suitable for heavier messes. However, it should not be used on delicate materials.
- Sprayway All Purpose Cleaner: This foaming aerosol cleaner clings to soils and effectively dissolves grease.
- WD-40 Specialist Degreaser: This is a popular choice for bicycle degreasers and is available at a reasonable price.
- Simple Green Industrial Cleaner and Degreaser: This is a bestselling degreaser that can be used for a variety of applications, including bicycles.
When using any degreaser, it is important to follow the instructions on the product label and take appropriate safety precautions, such as wearing gloves and ensuring adequate ventilation. Additionally, it is recommended to dispose of the used degreaser and cleaning water responsibly, avoiding drainage systems.

Soaking parts in diesel
To soak parts in diesel, one method is to fill a bucket with diesel fuel and submerge the parts overnight. The parts can then be scrubbed with a brush and rinsed with fresh diesel fuel. This process can effectively remove carbon deposits and leave the parts clean and shiny.
However, there are some concerns about the safety and environmental impact of using diesel as a cleaning agent. Diesel is a petroleum product and can leave an oily residue. It can also be harmful to human health, with potential risks including skin irritation, eye and throat irritation, and respiratory issues such as coughs and bronchitis. Long-term exposure to diesel exhaust may also increase the risk of developing asthma, lung diseases, heart disease, and brain and immune system issues.
In addition, diesel is not environmentally friendly and can cause ecological damage if disposed of improperly. It is important to avoid pouring diesel down the drain or into water bodies, as it can contaminate water sources and harm aquatic life.
There are alternative methods and products available for cleaning greasy parts that are safer and more environmentally friendly. These include commercial degreasers, citrus-based products, and terpenes. Some people also recommend using white spirit, kerosene, or paraffin followed by a water rinse and lube. When using any cleaning products, it is important to follow safety guidelines and wear appropriate protective gear, such as gloves and masks, to minimize the risk of exposure to harmful chemicals.

Rinsing and drying parts
Rinsing Parts:
- After soaking or scrubbing greasy parts in diesel fuel, it is essential to thoroughly rinse the parts with water.
- Use hot water for rinsing, as it will help remove any remaining diesel fuel or grease more effectively than cold water. Boil water if possible to ensure maximum heat.
- For complex parts with nooks and crannies, ensure that you work the hot water into all areas to remove any residual diesel or grease. A stiff brush can help work the water into tight spaces.
- Consider using a power hose or pressure washer for a more effective rinse, especially if dealing with heavily greased or dirty components. This will help dislodge any stubborn grease or fuel residue.
- If you're concerned about the environmental impact or want to avoid water waste, collect the rinse water in a container and dispose of it properly at a hazardous waste facility.
Drying Parts:
- After thoroughly rinsing the parts, it's crucial to dry them completely before proceeding with any further steps, such as painting or reassembly.
- Air drying is an option, but it may take a significant amount of time, especially for parts with intricate shapes that trap moisture.
- To expedite the drying process, consider using a hot air gun or a similar tool to accelerate the evaporation of water from the parts' surfaces and crevices.
- If you're working in a well-ventilated area or outdoors, you can use compressed air to blow-dry the parts. Ensure you wear eye protection when using compressed air to avoid any debris or moisture getting into your eyes.
- For smaller parts, you can also use clean, absorbent cloths or towels to wipe down the surfaces and speed up the drying process.
Remember, it's essential to follow safety precautions when working with diesel fuel and other cleaning agents. Always wear appropriate protective gear, including gloves, eye protection, and respiratory protection, to safeguard your health.
