How To Clean Rust From A Motorcycle Gas Tank

How to Clean Rust from a Motorcycle Gas Tank

So, you've got a motorcycle gas tank with rust. Don't despair! While it might seem like a daunting task, cleaning rust from a motorcycle gas tank is achievable with the right approach. This guide will walk you through several methods, from simple solutions for light rust to more intensive techniques for heavier corrosion. Remember, safety is paramount – always work in a well-ventilated area and wear appropriate safety gear.

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

Before you begin, it's crucial to determine the extent of the rust. This will dictate the best cleaning method.

Light Surface Rust:

This is the easiest to deal with. You'll likely see a reddish-brown discoloration on the tank's interior, but the metal itself is largely unaffected.

Moderate Rust:

Here, the rust is more substantial and may have started to pit the metal. You might see flaking or loose rust particles.

Heavy Rust:

This is the most serious case. Significant pitting and corrosion are present, and the tank may have holes or significant structural damage. In severe cases, tank replacement might be necessary.

Cleaning Methods for Different Rust Levels

The best method depends on the severity of the rust:

Method 1: For Light Surface Rust - The Simple Vinegar Soak

This is a gentle and effective method for light surface rust.

• What you'll need: White vinegar, plastic container large enough to hold the gas tank, rubber gloves, safety glasses.
• The process: Fill the container with enough white vinegar to completely submerge the gas tank. Allow it to soak for 24-48 hours, or even longer for stubborn rust. Periodically check and gently swirl the tank. Once the rust loosens, remove the tank and rinse thoroughly with water. Scrub with a soft brush if needed.

Method 2: For Moderate Rust - The More Aggressive Approach

For moderate rust, a more aggressive approach is needed.

• What you'll need: A commercial rust remover (follow manufacturer instructions carefully), a stiff brush (plastic or nylon is recommended to avoid scratching), plenty of water, rubber gloves, safety glasses.
• The process: Follow the instructions on your chosen rust remover. Often, this involves applying the remover, allowing it to dwell, then scrubbing with a brush. Rinse thoroughly with water after each application. Repeat as necessary until the rust is removed.

Method 3: For Heavy Rust - Professional Help or Replacement

Heavy rust requires professional help or, more likely, tank replacement. Attempting to repair a heavily rusted tank is often more trouble than it's worth and might compromise the tank's integrity.

Post-Cleaning Steps: Preparing Your Tank for Use

Regardless of the cleaning method, several post-cleaning steps are crucial:

• Thorough rinsing: Make absolutely sure all traces of the cleaning solution are removed. Any residue can contaminate your fuel.
• Drying: Dry the tank completely. You can air dry it or use compressed air.
• Inspection: Carefully inspect the tank for any remaining rust or damage.
• Sealing (Optional): For added protection, consider applying a fuel tank sealant to prevent future rust. This is particularly useful if you live in a humid climate.
