What You'll Learn
Use a pressure washer with diesel fuel or kerosene
Using a pressure washer with diesel fuel or kerosene is an effective way to clean out a 300-gallon fuel tank. This method is particularly useful if your tank is made of steel and has a lot of sludge and rust pieces at the bottom.
First, ensure you have the right equipment: a pressure washer, 5 gallons of diesel fuel or kerosene, and a drain at the bottom of your tank. If your tank does not have a drain, you can tilt it to one side to allow the contents to flow out more easily.
Next, prepare your pressure washer by feeding it with the diesel fuel or kerosene. It is important to note that diesel and water do not mix well, so avoid using water in this step. Once your pressure washer is ready, insert the nozzle through the fill hole at the top of the tank and begin spraying. Make sure to wear protective gear during this process, including gloves and eye protection.
As you spray, pay close attention to the bottom of the tank, where most of the sludge and rust buildup is likely to be. You may need to adjust the angle and position of the tank to ensure that all areas are thoroughly cleaned. Continue spraying until you are satisfied that the interior of the tank is free of debris.
Finally, once you have finished pressure washing, allow the tank to dry completely before refilling it with fuel. This step is crucial, as any remaining moisture can lead to rust formation, especially in steel tanks.
By following these steps and utilizing a pressure washer with diesel fuel or kerosene, you can effectively clean out your 300-gallon fuel tank, removing sludge and rust while also preparing it for future use.

Employ a degreaser and a high-powered water sprayer
To clean out a 300-gallon fuel tank using a degreaser and a high-powered water sprayer, there are several steps to follow. Firstly, it is important to identify the type of tank you have. If it is a steel tank, you will need to be cautious of rust issues. Inspect the tank for any signs of peeling paint or rust. If your tank is made of plastic, ensure that it is BPA-free and UV light-resistant, especially if you intend to store water in it for an extended period.
Next, choose an appropriate degreaser for the job. For a heavy-duty degreasing job, you can opt for an industrial purple cleaner like ZEP, which can be purchased from hardware stores. Remember to wear gloves and a mask during the cleaning process as the purple cleaner is an acid, although it is considered safe for the ground. Alternatively, for a more affordable option, you can use a liquid brake cleaner, which can be sprayed inside the tank using a compressed air nozzle with a pickup hose.
Once you have selected your degreaser, it's time to apply it to the tank. Pour the degreaser into the tank, ensuring that you follow the recommended quantities and safety instructions provided by the manufacturer. Allow the degreaser to sit for a while, and then drain it out. Repeat this process until the degreaser comes out the same way it went in, indicating that the tank is sufficiently clean.
After degreasing, you can use a high-powered water sprayer to rinse the tank. If your tank has small access holes, consider using a pressure washer with a steerable spray tip to effectively clean through the openings. You can also fill the tank with water and slosh it around to ensure that all surfaces are rinsed. Remember to drain the tank completely after rinsing.
Finally, to ensure that your tank is ready for use, it is recommended to perform a final flush with a liquid brake cleaner or kerosene. Any residual cleaner will evaporate quickly, leaving your tank dry and clean.

Steam clean the tank and let it dry
Steam cleaning is an effective method for cleaning a 300-gallon fuel tank. It is a process that has been used routinely by some and can be an ideal way to remove residue and sanitise the tank.
To begin the steam cleaning process, you will first need to remove the tank's bungs or plugs. This will give you access to the interior of the tank, allowing you to insert the steam cleaning wand. If your tank has only two small holes at the top, as is common in some fuel tanks, you may need to cut a larger access hole to fit the wand.
Once the tank is prepared, you can start the steam cleaning. Direct the steam through the openings or the access hole, thoroughly cleaning the interior surfaces. The steam's high temperature and moisture will help loosen and dissolve any built-up residue, sludge, or grime inside the tank. This process may take some time, depending on the level of soiling and the number of openings available for the steam wand.
After steam cleaning, the tank will need to be dried thoroughly. Water vapour will condense on the interior surfaces and accumulate at the bottom of the tank. Ensure that you give the tank sufficient time to dry before reuse.
It is important to note that steam cleaning may not be suitable for all fuel tanks, especially those made of steel, as moisture can cause rust. If you choose to steam clean a steel tank, ensure that you dry it promptly and consider using rust prevention methods, such as kerosene or industrial purple cleaner, to mitigate rust formation. Additionally, be cautious when handling the hot components of the steam cleaner to avoid burns or injuries.

Use a rag and stick, then roll with clean fuel and dump
If you're looking to clean out a 300-gallon fuel tank, there are several methods you can use, depending on the type of residue and the material of your tank.
One method is to use a rag and a stick, which can be effective for wiping away residue. You can attach the rag to the end of the stick and use it to scrub the inside of the tank. This method is especially useful if you're dealing with a thick layer of sludge or rust, as it allows you to physically remove the residue without the need for chemicals.
After scrubbing with the rag and stick, the next step is to roll the tank with clean fuel. This process helps to further loosen and remove any remaining residue. First, pour a small amount of clean fuel into the tank, just enough to cover the bottom. Then, roll the tank around so that the fuel washes over the interior surfaces. You can do this by hand or, if the tank is large and heavy, you might need to use a tractor or similar machinery to help you manoeuvre it. Once you've rolled the tank to your satisfaction, dump out the fuel and observe the results.
If there is still residue remaining, you can repeat the process of scrubbing with a rag and stick, rolling with clean fuel, and dumping. It may take several iterations to fully clean the tank, especially if there is a large amount of sludge or rust present.
It's important to note that this method assumes your fuel tank has small holes or openings at the top through which you can insert the rag and stick. If your tank is completely enclosed, you may need to consider other methods, such as using a pressure washer or steam cleaner, which can be fed through the existing openings. Additionally, always use proper safety equipment when working with chemicals and fuels, and dispose of any waste responsibly.

Chains and brushes to knock loose debris
Chains and brushes can be used to knock loose debris from a 300-gallon fuel tank. This method is similar to the tools and techniques chimney sweeps use to clean chimneys. A small chain, about a foot long, can be attached to the end of a rod and clamped to a battery drill to create a flail that can be used to dislodge debris from inside the tank.
This method can be particularly effective when combined with other cleaning techniques. For example, one person shared that they used kerosene and log chains inside their diesel tank, rolling it around with a front loader tractor to clean sediment and knock off rust. They reported that this method worked, as the tank was still in use years later.
Another individual suggested that if the tank is stationary, you could leave the dislodged debris to sit at the bottom and simply raise the pickup line. Alternatively, you could cut a section out of the top of the tank to access and remove the debris.
Before using chains and brushes, it is important to consider the size and placement of the holes or openings in your tank. If there are only small holes at the top, it may be challenging to effectively use chains and brushes to reach all areas of the tank's interior.
Additionally, be cautious when dealing with rust inside the fuel tank. While some suggest using water to clean the tank, others advise against it, stating that water can cause rust before the tank has a chance to dry. Instead, consider using diesel fuel or kerosene in combination with a pressure washer to spray and clean the interior of the tank.
