What You'll Learn
Removing rust with sheet rock screws, nuts and bolts, or rust remover acids
To clean a motorcycle fuel tank, you'll first need to remove the tank from the bike. Before you start, it's important to inspect the tank to determine the severity of the corrosion. If there are any cracks or small holes, seal them with rubber or vinyl vacuum caps.
If you're using rust remover acids, you'll need to take safety precautions due to the stronger fumes. Wear protective equipment and be mindful of safe acid disposal practices. The safest acid to use is white vinegar (acetic acid), which is inexpensive, non-toxic, and widely available. While it takes longer to remove rust, it is the least likely to damage the tank's metal. Other options include phosphoric acid or muriatic acid diluted with water, but these are stronger and can damage the metal if left inside the tank for too long.
To use vinegar, simply seal the filler with the cap, fill the tank with vinegar, and add water to the top. Let it sit for a couple of hours, then drain the tank and refill with clean water and baking soda to neutralize the acid. Drain and rinse well, then let it dry.
For a more aggressive approach, some people use sheet rock screws, nuts and bolts, or other abrasives like gravel or BBs. These items are placed inside the tank along with the chosen acid to help dislodge any rust particles. The acid makes the rust water-soluble, while the nuts and bolts knock off the bigger bits. After the acid treatment, rinse the tank with water and denatured alcohol to prevent new rust formation. Repeat this process until the metal looks clean.
It's important to note that when using nuts and bolts, the tank should be shaken and left in different positions to ensure all areas are cleaned. Additionally, the shape of the nuts and bolts can affect the ease of removal, so be cautious to avoid getting them stuck in the tank.
By following these steps and choosing the appropriate method for your situation, you can effectively remove rust from your motorcycle fuel tank.

Using electrolysis to convert rust to black iron oxide
To clean a rusty motorcycle fuel tank, one method that can be used is electrolysis. This process involves using a battery charger, washing soda, and a wire. The tank is filled with water, and the wire anode is inserted before turning on the current. This method is effective in removing rust from the tank and smaller individual pieces. It is important to note that electrolysis produces hydrogen gas, so it should be performed in a well-ventilated area, preferably outside. Additionally, the process leaves behind a black oxide residue that needs to be thoroughly cleaned off for any subsequent coating to adhere well.
The electrolysis method requires a direct line of sight to work effectively, with a clear path from the electrode to the affected area. It is important to ensure that there is no touching between the electrode and the affected area, as it will result in a short circuit. One user who employed this method reported that the coating of their tank came off, but they were able to recoat it successfully.
Another user shared their experience using a combination of phosphoric acid and electrolysis to clean their motorcycle fuel tank. They first cleaned the tank with water and sand, then flushed the sand out before cleaning with phosphoric acid. This user found that both methods were messy but not difficult. Phosphoric acid is available at paint stores and effectively cleans and prevents rust from reappearing.
While electrolysis can be an effective method for removing rust from a motorcycle fuel tank, it is important to consider the potential challenges, such as the production of hydrogen gas and the need for thorough cleaning of the black oxide residue. Additionally, the electrolysis method requires a direct line of sight and can cause issues with the tank's coating. Alternative methods, such as using phosphoric acid or plain white vinegar, can also be explored for cleaning and preventing rust in motorcycle fuel tanks.

Cleaning with vinegar
Cleaning a motorcycle fuel tank with vinegar is a safe, cost-efficient, and effective method. It is a good way to avoid the added expenses of replacing the tank altogether.
Firstly, it is important to note that strong acids can damage your bike and possibly cause serious injury. That is why white vinegar is recommended because it is strong enough to remove rust while remaining safe for your bike and your health. When working with chemicals and fuels, ventilation is essential. It is better to be safe and move outdoors.
Before cleaning, empty the fuel tank of any remaining fuel. Remove the petcock and block the hole. Try to wash out as much residue and debris as possible by rotating the gas tank. Next, fill the tank with vinegar and cover the tank hole with tape. Leave the fuel filler open and ensure that the tank is elevated above the basin, so the paint is never put in harm's way. The vinegar should be left for 24 to 48 hours, with occasional shaking of the tank. After this, the vinegar can be drained, and the tank can be rinsed with water. If there is still rust in the tank, the process can be repeated.
It is important to note that the vinegar method may not work for all tanks. Some users have reported success with this method, while others have experienced flash rust. Additionally, the vinegar method is time-consuming compared to other methods, such as using rust remover chemicals or acids. However, it is a safe and cost-effective option for cleaning a motorcycle fuel tank.

Sealing with Caswell
The Caswell Epoxy Gas Tank Sealer is a phenol novolac epoxy, a new breed of chemical-resistant material that can withstand permanent immersion in many harsh solvents, fuels, and oils, including ethanol-based fuels. This epoxy has much better bond strength than single-component products, with strengths of up to 3000 PSI. Its higher strength reduces the need for a clinically clean surface as it bonds better to a rough, rusty surface.
To use the Caswell Epoxy Gas Tank Sealer, first, plug the outlet ports with putty or Play-Doh. Then, mix the required amount of the sealer in a separate plastic container. One unit should treat two small motorcycle tanks or one large one; if treating only one small tank, divide parts A and B in half. Mix the two parts together thoroughly for at least 2 minutes, scraping around the sides to ensure all resin is blended.
After mixing, pour the sealer into the tank and seal the filler hole with plastic wrap and an elastic band. Swill the tank around in every direction for several minutes to obtain a good layer of sealer on all surfaces. Remove the filler cap and plastic wrap seal, and pour out any excess. Allow the tank to drain upside down for a few minutes. If your tank has a built-in fuel filter, blow air into the fuel line port for about 10 minutes.
Finally, place the tank in a warm 70-90-degree Fahrenheit place and allow it to cure overnight. For alcohol fuels, allow 3-5 days at room temperature or 24 hours at 120 degrees Fahrenheit.
