how to clean outside of black plastic fuel tanks

Cleaning the outside of a black plastic fuel tank is a simple process, but it requires caution to avoid damaging the tank. It is important to note that the use of certain chemicals, such as acetone, lacquer thinner, and muriatic acid, should be avoided as they can damage the plastic. Instead, a mixture of laundry detergent and water can be applied, followed by a gentle rinse. Alternatively, a high-pressure washer can be used to loosen sediment, and a safe grease remover can be applied afterward. For dried ethanol, a degreaser like WD40 or a non-chlorinated brake cleaner can be used.

Use a pressure washer

Using a pressure washer is an effective way to clean the outside of a black plastic fuel tank. It is a powerful tool that can remove dirt, grime, and debris from the tank's exterior surface. Here are some steps and guidelines to help you through the process:

Firstly, ensure you have the right equipment. A pressure washer with adjustable settings is ideal, as it allows you to control the water pressure and prevent potential damage to the plastic tank. Choose a model with a variety of nozzle options, as this will enable you to select the best spray pattern for your specific cleaning needs.

Before starting the pressure washer, carefully read the instructions provided by the manufacturer. Understand the safety precautions and proper usage guidelines. Pressure washers can be dangerous if not handled correctly, so take the necessary steps to protect yourself, such as wearing protective gear like goggles and gloves.

When you're ready to begin, start by adjusting the pressure washer to a suitable setting. It's generally recommended to start with a lower pressure setting and gradually increase as needed. Test the pressure on a small, inconspicuous area of the fuel tank to ensure it won't damage the plastic.

Once you've determined the appropriate pressure, begin washing the exterior of the tank. Use slow and steady movements, maintaining a consistent distance from the surface to ensure even cleaning. Pay close attention to any nooks and crannies, as well as areas with stubborn dirt or stains. You may need to adjust the nozzle or pressure setting to focus on particularly dirty spots.

After you've thoroughly washed the tank, it's important to rinse it with fresh water to remove any residual cleaning chemicals or soap. Ensure that all surfaces are rinsed, and there are no remaining traces of cleaning agents. Finally, allow the tank to air dry completely before refilling it with fuel or putting it back into use.

Using a pressure washer is a convenient and effective method for cleaning the outside of a black plastic fuel tank. By following these steps and safety guidelines, you can ensure a thorough cleaning process that will leave your fuel tank looking refreshed and well-maintained.

Steam cleaning

Firstly, ensure you have the necessary safety equipment. This includes eye protection, a face mask to reduce inhalation of fumes, and a fire extinguisher. It is also important to work in a well-ventilated area, so open doors and windows if working indoors.

Next, remove the fuel from the tank. This can be done by draining the fuel through a drain cock, if the tank has one, or by removing a gas line or syphoning the fuel. It is important to dispose of the old fuel responsibly, following environmental regulations. Contact your city waste management for advice on proper disposal.

Once the tank is empty, inspect it for any holes or damage. If there are any holes, they should be patched before continuing. Then, remove the gas tank, leaving all valves and caps in position. This will make reinstallation easier later on.

Now, the tank is ready for steam cleaning. You can either take the tank to a radiator or engine shop that offers steam cleaning services, or you can use a wallpaper steamer if you have one available. Ensure that you are able to access all areas of the tank by turning it and using the steamer through the inspection hatch.

After steam cleaning, you may wish to use a parts cleaner, such as Berryman B-12 Chemtool Fuel System Cleaner, to address any remaining sediment or buildup, especially on the bottom of the tank. You can also use a detergent-based fuel additive to ensure that your fuel system remains clean.

Finally, before reinstalling the tank, ensure that it is completely dry and that all valves, caps, and hoses are securely fitted. Check for any gas leaks, as even a slight leak can cause environmental damage or a fire.

Vinegar

To clean the outside of a black plastic fuel tank with vinegar, first, drain and rinse the tank. Then, fill the tank with vinegar and let it sit for 24 hours. If there is heavy rust buildup, you can add a handful of Sheetrock screws to the vinegar to help scrape away the rust. You can also add a little salt to the vinegar to improve and speed up the cleaning process.

After 24 hours, drain the vinegar and rinse the tank with clean water. To neutralize the vinegar and stop the cleaning process, add baking soda to the tank. Use one cup of baking soda for every two cups of vinegar used. Shake the tank to ensure the baking soda reaches all the areas treated with vinegar. Then, rinse the tank again with clean water. Repeat this rinsing process at least three times or until the water runs clear.

Finally, leave the tank to dry completely before reusing it. You can place it in the sun to speed up the drying process.

Degreaser

There are a few different types of degreasers that can be used. One option is to use a product called "Super Clean", which is a degreaser that comes in a large purple jug and can be purchased online. Another option is to use WD40, which also makes a degreaser that is suitable for cleaning fuel tanks. Additionally, some people have suggested using a product called "Industrial Purple" sold by Zep at Home Depot, or a non-chlorinated brake cleaner.

It is important to note that some people have expressed concerns about using chemical agents to clean plastic fuel tanks, as they may damage the plastic. Therefore, it is recommended to proceed with caution and test the degreaser on a small area first before applying it to the entire tank.

Additionally, it is worth mentioning that some people have had success cleaning their fuel tanks by using mechanical methods such as adding nuts, washers, or gravel to the tank and shaking it to remove the residue. However, these methods may not be as effective as using a degreaser and may require more effort and time.

Soapy water

Cleaning the outside of a black plastic fuel tank with soapy water is a straightforward process. First, remove the fuel tank and pour out any remaining fuel into a separate container. It is important to ensure that the fuel is disposed of safely and appropriately. Once the tank is empty, create a mixture of soap and water, and use a cloth or sponge to gently scrub the exterior of the tank. Rinse the tank with clean water to remove any remaining soap residue.

For more intensive cleaning, a detergent or laundry mixture can be used. Create a solution of boiling water and detergent or laundry detergent, following the instructions on the product for correct measurements. Place the fuel tank in the solution and roll it around to ensure all parts of the exterior are covered. Then, remove the tank from the solution and rinse it with clean water.

It is important to note that some sources recommend against using certain chemicals, such as acetone, lacquer thinner, and carb cleaner, as they can damage plastic tanks. Instead, natural alternatives such as lemon juice or vinegar can be used to clean the tank without causing damage. Additionally, gravel or nuts and washers can be placed inside the tank and shaken to help remove stubborn residue.

After cleaning the outside of the fuel tank, it is important to ensure that the tank is thoroughly dried before refilling it with fuel. This can be achieved by placing the tank in a well-ventilated area or using a portable vacuum to speed up the drying process.
