What You'll Learn
Using a pressure washer
To clean a plastic fuel tank using a pressure washer, you will first need to remove the tank and pull out the fuel pump and any other components. Drain the tank and then use the pressure washer to hose it out. It can be tricky to get the wand of the pressure washer into the tank, so you may need to fill and drain the tank with water a few times to ensure that all the residue is removed. You can also try adding a degreaser, such as Purple Power, to the water to help remove any stubborn residue.
Once you are satisfied that the tank is clean, you will need to dry it thoroughly. You can do this by leaving the tank to air dry, or by using a vacuum cleaner on the 'blow' setting, or with a hose attachment to remove any remaining water. You can also use a solvent, such as methyl hydrate, to speed up the drying process.
It is important to ensure that the tank is completely dry before refilling it with fuel. You can check this by pouring a small amount of fuel into the tank and checking for any residue. If there is still residue in the tank, repeat the process of draining, cleaning, and drying until it is completely clean.

Hot water and soap
Cleaning a plastic fuel tank is a delicate task, as the wrong cleaning methods can damage the plastic. One effective way to clean a plastic fuel tank is by using hot water and soap.
First, drain the tank of any fuel. Next, insert a hose into the fuel tank and begin pouring a stream of clean, hot water into it. While the water is filling the tank, spray a mild detergent or soap inside. If the opening allows, use a brush to loosen debris from the sides of the tank. Stop the stream of water and swish the water around to ensure all debris has been captured. Then, dump the dirty water into a pan, being careful to capture any liquids.
Wipe the tank out with a lint-free washcloth. Dry the tank completely with compressed air. If you don't have access to compressed air, you can let the tank air-dry in the sun for a few days. You can also use a vacuum to help speed up the drying process.
After the tank is dry, inspect it for any rust or physical damage. If any damage is present, the tank must be repaired or replaced. To ensure that any residual moisture is removed, add fuel line antifreeze or water remover to the tank. Let the tank sit for 30 minutes before refilling it with fuel.
Using hot water and soap is a safe and effective way to clean a plastic fuel tank. It is important to thoroughly clean and dry the tank to prevent any fuel pump issues or clogs caused by debris and contaminants.

Pine-sol and water
To clean a plastic fuel tank with Pine-Sol and water, start by removing any remaining fuel from the tank. Next, prepare a mixture of Pine-Sol and water. For a small fuel tank, dilute 1/16 cup (or 1 tablespoon) of Pine-Sol in half a gallon of warm water. For larger tanks, you can adjust the proportions accordingly.
Once you have prepared the mixture, carefully pour it into the fuel tank. Ensure that you have a safe and controlled environment to work in, and consider wearing protective gear such as gloves and eye protection. Completely fill the tank with the Pine-Sol and water solution. If your tank has a large opening, you may want to place the tank in a container that can catch any potential spills or drips.
Let the solution sit in the tank for at least 12 hours, and preferably for a couple of days. The Pine-Sol will work to dissolve any built-up residue or gunk inside the tank. After the soaking period, pour out the Pine-Sol mixture into a suitable container for disposal.
Rinse the tank thoroughly with fresh water to ensure that all traces of the Pine-Sol are removed. You can use a garden hose to rinse the tank and let the water run through for a while. Finally, drain every bit of water from the tank and dry it thoroughly. You can use a portable vacuum to speed up the drying process.

Draining and shaking
First, drain the fuel tank by removing the fuel pump and any other components that may be in the way. You can then begin the process of emptying the tank of its contents. If there is a significant amount of fuel left in the tank, you may need to siphon it out or use a pump to remove it safely. Once the bulk of the fuel has been drained, you can then remove the tank and turn it upside down to allow any remaining fuel to drip out. It is important to ensure that the area where you are working is well-ventilated and that you take the necessary precautions to avoid any potential hazards associated with handling fuel.
Next, you can begin the shaking process. This step will help to dislodge any built-up residue or debris inside the tank. Before shaking, it is recommended to add a small amount of fuel or cleaning solution to the tank. You can then securely replace the cap and shake the tank vigorously. This process may need to be repeated several times until you are satisfied that the tank is clean. After shaking, remove the cap and drain the contents once more.
For a more intensive cleaning, you may need to use a cleaning agent such as Pine Sol or a similar product. In this case, you would follow a similar process by adding a mixture of the cleaning agent and water to the tank, allowing it to sit for several days, and then draining and rinsing the tank thoroughly. It is important to follow the recommended ratios and safety instructions when using any cleaning products.
Finally, after draining and shaking, it is crucial to ensure that the fuel tank is completely dry before refilling it with fuel. You can use compressed air to remove any remaining water droplets or moisture from the tank. Alternatively, you can use a portable vacuum with a hose attached to the exhaust to accelerate the drying process. Leaving the tank in a safe place to air dry for an extended period is also recommended.

Compressed air
First, drain the fuel tank and remove it from the vehicle. It is important to ensure that the tank is completely empty and free of any residual fuel. You can do this by tilting the tank and allowing the fuel to drain out through the bottom valve or by using a siphon pump to remove the fuel.
Next, fill the tank with a cleaning solution. You can use a mixture of mild soap and water, or a specialised fuel tank cleaner. Some people also recommend using a small amount of fuel, such as diesel, to help loosen any built-up debris. Securely replace the cap and shake the tank vigorously to ensure that the solution coats the interior surfaces.
After allowing the cleaning solution to sit for a few minutes, you can begin using compressed air. There are a few ways to do this:
- Using an air compressor: If you have access to an air compressor, you can use it to blow compressed air into the tank through the fuel filler neck. Ensure the tank is well-ventilated and wear protective gear.
- Using an air hose: Alternatively, you can attach an air hose to a compressed air source and feed it into the tank. Again, ensure adequate ventilation and wear protective equipment.
- Using an air-powered vacuum cleaner: Another option is to use an air-powered vacuum cleaner, which can simultaneously blow compressed air and vacuum out any remaining debris and liquids.
When using compressed air, be cautious and avoid pointing the air stream directly at yourself or others. Ensure that the tank is in a well-ventilated area to prevent the buildup of fumes.
Finally, after blowing compressed air through the tank, leave the tank open and allow it to air-dry completely. You can place it in direct sunlight or use a fan to speed up the drying process. Once the tank is thoroughly dry, you can re-install it in your vehicle, ensuring that all connections are secure.
