How To Get Rust Out Of Motorcycle Gas Tank

How to Get Rust Out of a Motorcycle Gas Tank

Rust in your motorcycle's gas tank is a common problem that can severely impact performance and even damage your engine. Fortunately, there are several methods to effectively remove rust and restore your tank to its former glory. This guide will walk you through various techniques, from simple cleaning to more involved restoration processes. Remember safety first! Always work in a well-ventilated area and wear appropriate protective gear.

Assessing the Damage: How Much Rust Are We Dealing With?

Before you begin, it's crucial to assess the extent of the rust. A little surface rust is manageable, but heavy pitting requires a more drastic approach.

• Light Surface Rust: This is often just a discoloration and can usually be cleaned with a chemical solution.
• Moderate Rust: You might see some pitting or flaking rust. This will likely require more aggressive cleaning.
• Heavy Rust: Significant pitting and possibly holes in the tank. This might require professional repair or tank replacement.

If you have heavy rust and significant pitting, professional restoration may be the best option. This guide focuses on solutions for light to moderate rust.

Cleaning Methods for Removing Rust from Your Motorcycle Gas Tank

Here are several methods you can try, starting with the simplest:

1. The Simple Rinse and Brush Method (For Light Surface Rust)

This is the most basic approach and only works for minimal surface rust.

• Thoroughly Rinse: Flush the tank with water several times to remove loose rust particles.
• Scrub with a Brush: Use a long-handled brush (a bottle brush works well) to scrub the inside of the tank, removing as much loose rust as possible.
• Rinse Again: Rinse the tank thoroughly once more.
• Dry Completely: Allow the tank to dry completely before proceeding.

2. Using Vinegar (For Light to Moderate Rust)

Vinegar is a mild acid that can effectively dissolve rust.

• Fill the Tank: Fill the tank with white vinegar.
• Let it Soak: Allow the vinegar to soak for at least 24 hours, or longer for heavier rust. The longer it soaks, the better the results. Agitate occasionally by gently swirling the tank.
• Rinse Thoroughly: After soaking, thoroughly rinse the tank with water multiple times until all traces of vinegar are gone.
• Dry Completely: Allow the tank to dry completely.

3. The Nuts and Bolts Method (For Moderate Rust)

This method uses abrasion to remove rust. It's more aggressive than vinegar.

• Add the Abrasives: Place several clean nuts and bolts, along with a small amount of water, in your gas tank.
• Shake it Up: Seal the tank opening and shake vigorously for a considerable length of time to allow the nuts and bolts to scrape off the rust.
• Rinse Thoroughly: Rinse the tank several times until all traces of rust are gone.
• Dry Completely: Allow the tank to dry completely.

4. Using a Commercial Rust Remover (For Moderate Rust)

Several commercial rust removers are available specifically designed for gas tanks. Always follow the manufacturer's instructions carefully. These usually involve rinsing, soaking, and then further rinsing.

Post-Cleaning and Prevention

After cleaning your gas tank, ensure it is thoroughly dry. Consider using a compressed air system to remove any lingering moisture. You can then apply a fuel tank sealant to protect the cleaned surface and prevent future rust formation.

Prevention is key: Keep your gas tank full to minimize air exposure, which contributes to rust formation. Also, use a fuel stabilizer, especially during periods of storage, to prevent water condensation.

Remember to always take safety precautions when working with chemicals and cleaning your motorcycle parts. If you're unsure about any step, it's always best to seek professional help.
