The internet is rife with suggestions, from using a pressure washer or garden hose to spraying it out with water and compressed air.

Using gravel to clean the tank
To clean a black plastic fuel tank, one method that can be employed involves the use of gravel. This method is particularly useful for removing stubborn dirt, rust, and debris from the tank. Here is a step-by-step guide on how to effectively clean your black plastic fuel tank using gravel:
First, remove the fuel tank from your vehicle or equipment and find a suitable location to hang it securely. You can use a rope to hang the tank from a sturdy structure like a tree or a swing. Ensure that the tank is securely fastened to prevent any accidents.
Next, prepare the gravel. It is recommended to use aquarium gravel as it comes in various sizes and can effectively reach all corners of the tank. Place a handful of gravel into the fuel tank, ensuring it is dry and free of any dust or debris.
Once the gravel is inside the tank, vigorously shake the tank back and forth. The gravel will act as an abrasive agent, scraping away any dirt, rust, or debris that may be stuck inside. You may need to shake the tank for several minutes to ensure that all the contaminants are loosened.
After shaking, carefully remove the gravel from the tank. You can do this by tilting the tank and pouring out the gravel, or by using a small magnet if the gravel is magnetic. It is important to ensure that all the gravel is removed to avoid any residual debris remaining in the tank.
Finally, rinse the fuel tank thoroughly with water. You can use a water hose to flush out any remaining gravel dust and loosened contaminants. Ensure that you direct the water into all corners of the tank and rinse until the water runs clear.
Using gravel to clean a black plastic fuel tank is an effective method that can be repeated if necessary. It is important to avoid using chemicals or solvents on plastic fuel tanks, as these can cause damage. Instead, a simple combination of gravel and water can safely and effectively restore your fuel tank to a like-new condition.

Using vinegar to clean the tank
Vinegar can be used to clean a plastic fuel tank. It is an acid that can help to remove rust from the tank.
First, remove the gas tank and empty it. Then, fill the tank with vinegar and leave it to soak for 24 hours. After this, the vinegar should be neutralised with baking soda and rinsed out with water. This process may need to be repeated several times, depending on the level of rust in the tank.
Apple cider vinegar is recommended due to its higher acidity. However, it is important to note that vinegar can be damaging to rubber, so it should be avoided if there are any rubber fuel lines or fittings in the tank.
Some people recommend adding a handful of Sheetrock screws or gravel to the vinegar to help loosen and remove rust and debris from the tank. This can be done by shaking the tank or attaching it to a cement mixer or bike wheel and turning it.
After cleaning with vinegar, it is important to dry the tank thoroughly with an air hose and then coat the inside of the tank with oil or fuel to prevent rusting.

Using degreaser to clean the tank
It is important to clean your fuel tank from time to time to prolong the life of your fuel filter and engine. Before you begin, ensure that you are working in a well-ventilated area, with no sources of flame or spark nearby. Keep a fire extinguisher handy. Wear protective clothing, including a face mask and eye protection, and ensure the tank is empty of fuel.
Using a degreaser is an effective way to clean your fuel tank. First, drain all the fuel from the tank using an approved container or a fuel caddy. Some gas tanks have a drain cock, allowing the fuel to be drained neatly. If not, you can drain the fuel by removing a gas line or by syphoning it. Once the tank is empty, carefully remove the gas tank, but leave all valves and caps in position. This will make the reinstallation process much simpler later on.
Next, you will want to use a degreaser such as 'Super Clean' or WD40's degreaser. These products can be purchased in large quantities, so you will have plenty to use for multiple cleaning sessions. Ensure the degreaser is dispersed over the entire inside surface of the tank by shaking or swirling it. The majority of the buildup will be on the bottom, so focus most of your attention there. It may take a few soaking sessions to get the bottom completely clean, depending on the amount of buildup.
After the degreasing step, you may want to follow up with additional cleaning steps, such as rinsing the tank with clean water and mild detergent, or using a parts cleaner like Berryman B-12 Chemtool Fuel System Cleaner. Remember to dry the tank completely with compressed air and inspect it for any damage before reinstalling.

Removing the tank and cleaning it
Removing and cleaning a fuel tank can be a daunting and labor-intensive task. It is important to take safety precautions, as fuel is highly combustible and can be dangerous. Here are some detailed steps to guide you through the process of removing and cleaning your black plastic fuel tank:
Removing the Tank:
- De-clutter your work area to prevent accidents and ensure a smooth process.
- Ensure proper ventilation by opening doors and windows, and consider setting up a fan to maintain a fresh airflow.
- Have a fire extinguisher readily available and eliminate any sources of flame or sparks in the vicinity.
- Wear protective gear, including a face mask to minimize fuel fume inhalation and eye protection to safeguard against any potential splashes or debris.
- If your vehicle has a drain cock, you can neatly drain the fuel by opening it. Otherwise, you may need to drain the fuel by removing a gas line or using a siphoning method.
- Carefully remove the gas tank, keeping all valves and caps in position to simplify the reinstallation process later.
Cleaning the Tank:
- Once the tank is removed, thoroughly inspect it for any signs of sediment, rust, or holes. Patch any holes before proceeding.
- Use a reliable parts cleaner, such as Berryman B-12 Chemtool Fuel System Cleaner, to address the interior of the tank. Swirl or shake the tank to ensure the product reaches all surfaces, paying extra attention to the bottom, where most buildup occurs.
- Consider using gravel or a small chain to dislodge any stubborn dirt or rust. You can also use aquarium gravel, which is effective at reaching corners and tight spaces.
- Rinse the tank thoroughly. If you have access to a high-pressure washer, this can be an effective way to ensure a thorough clean. Alternatively, you can hang the tank from a rope and use a water hose to rinse it out.
- Finally, before reinstalling the tank, ensure that all valves, caps, and hoses are securely fitted to prevent gas leaks.
Remember to always prioritize safety and follow specific guidelines for your vehicle or equipment when removing and cleaning your fuel tank.

Using soap and water to clean the tank
To clean a black plastic fuel tank using soap and water, first, pour out all the gas and remove any large residue. Put on some old clothes and take the tank to a car wash. Wash out the tank with soapy water. You can use regular dish soap or a specialised cleaner such as Pinesol. Pour out the soapy water and check inside for any residue. Repeat the process if necessary.
Then, take the tank home and put it somewhere it can drain without damaging your grass. Put a hose inside the tank and let it run for a while. Drain all the water from the tank. If you have a portable vacuum with a hose, you can use it to dry the tank further.
Alternatively, you can use the shake method. First, seal the tank. Then, put in some soap, hot water, and a handful of small objects such as nuts, bolts, or gravel. Shake the tank vigorously, then remove the contents and wash out with a hose.
You can also use a pressure washer with hot, soapy water. Afterward, use a vacuum cleaner on blow or some methyl hydrate to dry the tank.
