Rusty Motorcycle Gas Tank
If you’re a motorcycle owner, you know that rust can be a real pain when it comes to your bike’s gas tank. Not only can it cause clogs and engine damage, but it also just looks plain ugly. Luckily, there are some great products and methods out there to help you get your tank looking like new again.
One of the best products is Evapo-Rust. This product is non-toxic and safe to use, making it a great choice for those who are concerned about the environment and their health. It’s easy to apply and works quickly to remove rust from the tank.
Another method for cleaning a rusty motorcycle gas tank is using a combination of vinegar and baking soda. It’s an affordable and easy-to-find solution that can effectively remove rust from the inside of the tank. Simply mix equal parts of white vinegar and baking soda to create a paste and apply it to the rusted area. Let it sit for a few hours or overnight, and then rinse it out with warm water.
When it comes to prevention, there are a few things you can do to keep your tank from rusting in the first place. One is to keep it full of fuel as much as possible, which will help prevent moisture from building up inside the tank. You can also use a fuel stabilizer to keep the fuel from going bad and causing rust.
Best Methods to Solve Rusty Motorcycle and Comparison Table
Method 1: Evapo-Rust Evapo-Rust is a rust remover that’s safe and easy to use. You simply pour it into your tank, let it sit for a few hours, and then rinse it out. This product is non-toxic and environmentally friendly, so it’s a great choice for those who are concerned about using harsh chemicals. However, it can be a bit expensive and may not work as well on heavily rusted tanks.
Method 2: Electrolysis Electrolysis is a method for removing rust that involves using a battery charger and some simple materials to create a chemical reaction. This method is effective and relatively inexpensive, but it can be time-consuming and requires some basic knowledge of chemistry.
Method 3: Coating Coating involves using a special product to create a barrier between the metal and the fuel. This method is effective at preventing rust from forming, but it can be expensive and may require professional installation.
Method 4: Replacement If your tank is severely rusted and damaged, you may need to replace it altogether. While this is the most expensive option, it’s also the most effective at ensuring your motorcycle is running safely and smoothly.

Step-by-Step Instruction on How to Clean Rusty Motorcycle Gas Tank
- Safety first – put on safety goggles and gloves to protect your eyes and skin from rust and chemicals.
- Drain the tank completely of fuel, remove the fuel lines and petcock. This can be done by disconnecting the lines and letting any remaining fuel drain out.
- Determine the severity of the rust in the tank. Light rust can often be removed using rust remover, while severe rust may require the electrolysis method.
- For rust remover, pour the recommended amount of product into the tank, swish it around, and let it sit for the recommended amount of time. Be sure to follow the instructions provided with the product carefully.
- For electrolysis, mix a solution of water and baking soda and fill the tank. Connect the negative lead of a battery charger to the tank, and the positive lead to a sacrificial piece of metal (such as a steel rod) that’s also in the tank. Turn on the charger and let the electrolysis process run for several hours.
- Once the rust has been removed, rinse out the tank with a hose or clean water until the water runs clear. Be sure to rinse out any remaining rust remover or electrolysis solution.
- Dry the tank thoroughly with clean rags or towels.
- To prevent future rust, consider using a fuel stabilizer and/or coating the tank with a rust-preventative product. If coating, follow the instructions provided with the product carefully.
- Reinstall the fuel lines and petcock, and fill the tank with fresh fuel.
Remember to always read and follow the instructions provided with any product or method to ensure safety and effectiveness. With these steps, you should be able to successfully clean your rusty motorcycle gas tank and get back on the road with confidence.

FAQ
Can I clean the tank while it is still on the motorcycle?
It is possible to clean the tank while it’s still on the motorcycle, but it can be more difficult and time-consuming to do so. Removing the tank from the motorcycle will make the cleaning process easier and safer.
What is the best rust remover to use on a motorcycle gas tank?
The best rust remover will depend on the severity of the rust and your personal preferences. There are many rust remover products available on the market, and each one has its own set of instructions and safety precautions. Always choose a reputable brand and follow the instructions carefully to ensure safety and effectiveness.
Can I coat the tank with paint to prevent rust?
While paint can provide some protection against rust, it is not a permanent solution. Over time, paint can crack and chip, which can expose the metal underneath to moisture and cause rust to form. To provide long-lasting protection against rust, consider using a specialized rust-preventative product designed specifically for metal tanks.
How often should I clean my motorcycle gas tank?
The frequency of cleaning your gas tank will depend on how often you use your motorcycle and the conditions in which it is stored. If you use your motorcycle frequently, it is recommended to clean the tank at least once a year. If your motorcycle is stored for long periods of time or in a damp environment, it may be necessary to clean the tank more often to prevent rust from forming.
Can I reuse the fuel that was in the tank before cleaning it?
No, it is not recommended to reuse the fuel that was in the tank before cleaning it. The fuel may have been contaminated with rust particles and other debris, which can damage your engine. It is recommended to dispose of the old fuel properly and fill the tank with fresh, clean fuel after cleaning it.
