Aluminium fuel tanks are widely used across industries due to their lightweight, durable, and corrosion-resistant nature. However, to maintain their properties, these tanks require regular cleaning and maintenance. Cleaning methods vary depending on whether you are cleaning the inside of the tank or the outside, and the type of residue you are trying to remove. For instance, to clean the inside of an aluminium fuel tank, you can use products like Gumout, Pyroil, Holley, or CRC to dissolve varnish and gummy residues. Alternatively, you can use fresh gasoline, such as E-85 or E-10 gas, as the ethanol acts as a solvent. For the outside of the tank, you can use commercial products like Aluma-Brite, Eagle Mag Wheel Cleaner, or Heavy Metal polishing compounds. It is important to note that some of these products are acids and require careful handling and proper disposal of the wash.

Spray-on products like Aluma-Brite can be used to clean aluminum fuel tanks
Aluminium fuel tanks are widely used across industries due to their lightweight, durable, and corrosion-resistant nature. However, they require regular cleaning and maintenance to sustain their properties.
Spray-on products like Aluma-Brite can be used to clean aluminium fuel tanks. Aluma-Brite is a mild acid that can be sprayed on and rinsed off quickly to avoid streaking. It is important to note that there is a small window between the aluminium being cleaned and it burning white, so timing is crucial. It is also recommended to wear gloves and a mask when using this product.
Other spray-on products that can be used include Eagle 1 A to Z Wheel Cleaner, which is strong enough to loosen caked-on sludge without damaging the metal. This can be sprayed into the tank, followed by a small amount of water, and left to soak before draining and repeating if necessary.
For the interior of aluminium fuel tanks, an acid wash or fuel tank cleaner can be used. This involves filling the tank with water and adding a cup of muriatic acid, repeating the process until the wash becomes clear. It is important to properly dispose of the contents after cleaning. Additionally, a metal chain can be put inside the tank and rolled to loosen and remove rust from the surfaces, which can then be rinsed out with water.
Before installing a cleaned aluminium fuel tank back into a vehicle or boat, it is crucial to ensure it is completely dry for at least 24 hours to avoid any potential issues.

Acid wash or fuel tank cleaner can be used to remove rust from aluminum fuel tanks
Several methods can be used to remove rust from aluminum fuel tanks, including acid wash and fuel tank cleaners.
One popular method is to use muriatic acid, a type of hydrochloric acid. Muriatic acid is a potent substance that can effectively remove rust from fuel tanks. However, it requires careful handling due to its strength and potential health risks. To use muriatic acid, seal all openings of the fuel tank except for the fuel fill. Wear gloves, a cartridge-type charcoal respirator, and other appropriate personal protective equipment (PPE). Pour in enough muriatic acid to slosh around and then tip and roll the tank to ensure the acid covers all interior surfaces. Check the progress periodically through the filler, and add more acid if needed. Once the desired level of derusting is achieved, neutralize the acid with a base like baking soda and flush the tank with warm water. After derusting, apply a product like Red Kote to prevent flash rusting.
Another method for removing rust is to use a commercial fuel tank cleaner, such as Chevron Techron (PEA), Berryman, SeaFoam, Gumout, or Evapo-Rust. These products are designed to dissolve varnish, gummy residues, and rust inside fuel tanks. Follow the instructions on the product labels for proper usage. Some products may require mixing with gasoline or water and can be used in combination with a carb/FI cleaner for added detergency.
Alternative methods for removing rust from fuel tanks include using apple cider vinegar and clean round stones, shaking the tank with nuts or bolts, or using ammoniated citric acid or ammonium citrate. These methods may be less potent than acid wash or commercial fuel tank cleaners but can still effectively remove rust with proper techniques.

Varnish and gummy residues can be dissolved using liquids like Gumout, Pyroil, and Holley
Liquids such as Gumout, Pyroil, and Holley can be used to dissolve varnish and gummy residues from aluminum fuel tanks. These products are designed to remove varnish, sludge, and carbon deposits.
Gumout, for example, can be used to clean any metal parts without compatibility issues, although it should be kept away from plastic or painted surfaces. It is recommended to use Gumout 2-Cycle Oil at the treat rate suggested by the engine manufacturer, mixing it with gasoline before starting the engine.
Pyroil is another option that can be used to clean carburetors, chokes, PCV valves, and throttle linkages. It dries without leaving any residue and is safe for oxygen sensors and catalytic converters.
Holley users have reported success in cleaning their carburetors with mineral spirits, light brushing, compressed air, and brake cleaner. Some have also recommended using a Holley Rebuild Kit for a more comprehensive cleaning.
It is important to note that some cleaning solutions may strip the color from your aluminum fuel tank, so it is recommended to test a small area first or follow the specific instructions provided by the manufacturer. Additionally, some sources suggest using aluminum brightener, an acidic cleaner that foams up and can be rinsed off, but it will also remove any polish.

Gasoline can be used to clean aluminum fuel tanks, especially E85 gasoline
To clean the inside of an aluminum fuel tank, you can use a solvent such as gas or denatured alcohol. First, slosh the solvent around inside the tank, then let it dry completely. If there is any residue left, it should be baked-on dust that can be easily removed with a nylon brush. You can also use ice cubes, salt, and toilet bowl cleaner to scrub the tank clean. Just be sure to rinse well afterward.
There are also commercial products available that can be mixed with gasoline to clean the inside of aluminum fuel tanks. These include Gumout, Pyroil, Holley, and CRC. These products can help dissolve any varnish or gummy residues in the tank. After using one of these products, you may want to use a carb/FI cleaner in the first few tanks to add extra detergency and dissolve any remaining residues.
Another option for cleaning the inside of an aluminum fuel tank is to use an acid-based product like aluminum brightener. This will remove any grime and polish the surface, but it will turn the aluminum white. Be careful not to use muriatic acid, as this will turn the aluminum black.
It is important to note that some sources advise against using gas to clean an aluminum fuel tank. One person shared their experience of cleaning their aluminum tank, only to find that it developed small spots that seeped gas. They ended up having to get a new bottom welded in. Therefore, it is recommended that after cleaning, you pressure test the tank with air (about 3 PSI) and spray soapy water all around it to check for leaks.

A metal chain can be put inside the tank and rolled to loosen and remove rust
Aluminium fuel tanks are popular due to their lightweight and durable nature. They are also resistant to corrosion. However, they do require regular cleaning and maintenance to sustain their properties.
To clean an aluminium fuel tank, the first step is to remove it from the car or boat. Then, you can wash it out with water to remove any excess fuel. You can use a garden hose or any other tool to rinse it thoroughly.
Even though aluminium fuel tanks are corrosion-resistant, the inside of the tank can still rust over time. To remove the rust, a metal chain can be put inside the tank and rolled around to loosen and remove the rust from the surfaces. The tank should be rinsed with water during this process to wash away the loosened rust.
After removing the rust, you can wash the tank with an acid wash or a dedicated fuel tank cleaner. If using a cleaner, you may want to leave the solution in the tank overnight before rinsing and drying it the next day. It is important to wear protective gear when handling these cleaning agents.
There are also various products available to dissolve any residue or varnish inside the tank, such as Gumout, Pyroil, Holley, or CRC. These can be mixed with gasoline and swished around to clean the tank. Regular gasoline can also be used, as the ethanol acts as a solvent. The tank should be shaken vigorously to ensure all surfaces are cleaned.
