A sputtering lawn mower can be a real buzzkill, especially when you’re trying to maintain a pristine lawn. One common culprit for these engine woes is a dirty gas tank. While it’s easy to think “just replace it,” a well-maintained plastic gas tank can serve you well for many seasons. This comprehensive guide will walk you through the process of cleaning your plastic lawn mower gas tank, ensuring a smooth-running engine and a satisfying mow.
In a nutshell, cleaning a plastic gas tank involves a thorough removal of debris and residue, followed by a meticulous rinsing and drying procedure. This process requires careful handling to avoid damaging the tank’s delicate plastic. Read on to learn how to do it right, and get your lawn mower back in action!
Getting Started: Preparation is Key
Before diving into the cleaning process, it’s crucial to gather the necessary tools and prepare your workspace. Here’s what you’ll need:
- Safety Glasses: Protect your eyes from potential splashes.
- Gloves: Prevent skin irritation from gasoline fumes and residues.
- Old Towels: Protect your work area from spills.
- A Well-Ventilated Area: Avoid working in enclosed spaces due to the volatile nature of gasoline.
- A Drain Pan or Container: To catch any spilled gasoline.
- A Cleaning Solution: We’ll discuss suitable options later in this guide.
- Clean Water: For rinsing the tank.
- A Funnel: To help pour in the cleaning solution.
- A Brush: To loosen stubborn debris.
Now that you have your tools ready, it’s time to prepare the tank for cleaning. This involves:
- Disconnecting the Fuel Lines: Carefully detach the fuel lines from the tank, using appropriate tools if necessary.
- Emptying the Tank: Remove any remaining gasoline, either by draining it into a suitable container or by siphoning it out.
- Inspecting for Damage: Check for any cracks or leaks in the tank. If you find any, it’s best to replace the tank rather than attempting to repair it.
Cleaning Strategies: Choosing the Right Approach
Now that your tank is empty and ready for cleaning, you need to select a cleaning solution. There are several effective options available:
1. Using a Gas Tank Cleaner
Specifically designed for cleaning gas tanks, these products effectively remove residue and varnish buildup. They are generally safe for plastic tanks, but always refer to the product instructions for compatibility.
- Pros: Highly effective, readily available.
- Cons: Can be expensive, some may require specific ratios with gasoline.
2. Employing a DIY Solution
For a more budget-friendly approach, you can create your own cleaning solution using household ingredients. Here are some effective options:
A. Vinegar & Baking Soda
- Mix: 1 cup of vinegar with 1/2 cup of baking soda.
- Pros: Environmentally friendly, readily available.
- Cons: Not as effective as commercial cleaners for stubborn buildup.
B. Diesel Fuel
- Use: Pure diesel fuel can be effective for cleaning out old gas tank residue.
- Pros: Easy to find, often cheaper than specialized cleaners.
- Cons: Can be harsh on plastic, use with caution and rinse thoroughly.
C. Isopropyl Alcohol
- Mix: A solution of isopropyl alcohol and water (around 50/50).
- Pros: Effective for dissolving gum and varnish, relatively safe for plastic.
- Cons: Not as effective for stubborn dirt or debris.
Choosing the Right Approach for You
The ideal cleaning method depends on the condition of your tank and your personal preference. If you have stubborn buildup, using a specialized gas tank cleaner is often the most effective option. However, if you have a less dirty tank or prefer a more environmentally friendly approach, DIY solutions can be a good choice.
The Cleaning Process: Step-by-Step Guide
Once you’ve chosen your cleaning solution, it’s time to get down to business. This step-by-step guide will help you clean your plastic gas tank effectively:
- Pour the Cleaning Solution: Using a funnel, carefully pour your chosen cleaning solution into the tank. Ensure it fully coats the inner surface.
- Agitate the Tank: Swirl the tank gently to distribute the cleaning solution and loosen any debris. If you have a brush, use it to scrub stubborn areas.
- Let it Sit: Allow the cleaning solution to sit in the tank for at least 30 minutes to an hour. This allows the solution to break down stubborn residue.
- Empty the Tank: Drain the cleaning solution into your drain pan or container.
- Rinse Thoroughly: Flush the tank with clean water several times to remove any remaining cleaning solution and debris. Make sure no residual cleaner is left behind.
Drying the Tank: A Critical Step
A properly dried tank is essential for preventing corrosion and ensuring a smooth engine start. Here’s how to ensure your tank is completely dry:
- Air Dry: Allow the tank to air dry completely. This can take several hours or even overnight, depending on the temperature and humidity.
- Assisted Drying: You can speed up the drying process by using a hairdryer on a low heat setting. Avoid using a blow torch or high heat, as this can damage the plastic.
- Compressed Air: For a thorough drying, consider using compressed air to blow out any remaining moisture.
The Final Touches: Reassembly and Prevention
Once your tank is completely dry, it’s time to reassemble it and prepare for its next use.
- Reinstall the Fuel Lines: Carefully reconnect the fuel lines to the tank.
- Inspect for Leaks: Before putting fuel back into the tank, check for any leaks by giving the lines a slight squeeze.
- Fill with Fresh Fuel: Fill the tank with fresh, clean gasoline.
- Prevent Future Buildup: Consider adding a fuel stabilizer to your tank to prevent the formation of varnish and gum deposits over time.
Conclusion: A Clean Tank, A Smooth Mow

FAQ
Q1: Why do I need to clean my lawnmower gas tank?
A: Cleaning your lawnmower gas tank is essential for maintaining its optimal performance and extending its lifespan. Over time, fuel can degrade and leave behind sediment, varnish, and rust, which can clog fuel lines, restrict fuel flow, and ultimately damage the engine. A clean gas tank ensures a smooth fuel supply, preventing engine sputtering, stalling, and potential breakdowns.
Q2: What are the potential hazards of cleaning a gas tank?
A: Cleaning a gas tank involves working with flammable substances, so safety precautions are crucial. Always work in a well-ventilated area away from any open flames or sparks. Wear protective gear like gloves, eye protection, and appropriate clothing to prevent spills and skin contact. Dispose of any fuel or cleaning solutions responsibly, following local regulations.
Q3: What cleaning supplies do I need?
A: You’ll need a few essential supplies for cleaning your gas tank. These include a suitable cleaning solution, such as a dedicated gas tank cleaner or a mixture of white vinegar and water. A funnel, a siphon pump, rags, and a container to collect the fuel are also necessary. Ensure you have a safe and well-ventilated area to work in, and wear appropriate safety gear.
Q4: How do I safely remove the fuel from the tank?
A: It’s crucial to safely remove the fuel from the tank before cleaning it. First, ensure the engine is cool and the ignition is off. Then, using a siphon pump or a turkey baster, carefully remove the fuel and store it in a designated container. Never discard fuel directly into the environment; dispose of it responsibly at a designated collection point.
Q5: How do I clean the inside of the gas tank?
A: After emptying the tank, pour in your chosen cleaning solution and allow it to sit for several hours. You can gently shake or rotate the tank to ensure the solution reaches all areas. Once the cleaning time is complete, drain the solution and rinse the tank thoroughly with water. Allow the tank to dry completely before reassembling it.
Q6: How do I prevent future buildup in my gas tank?
A: You can minimize the buildup of sediment and varnish in your gas tank by using fuel stabilizers and avoiding leaving fuel in the tank for extended periods. It’s also crucial to use fresh, high-quality fuel. If you anticipate storing your lawnmower for a longer time, run the engine until it’s empty and then add a fuel stabilizer before storing it.
Q7: What should I do if I can’t clean the gas tank myself?
A: If you’re unsure about cleaning your gas tank yourself or have a particularly stubborn case of buildup, it’s best to seek professional assistance. A qualified mechanic can safely clean the tank and ensure it’s in optimal condition. This is particularly recommended if you notice any significant performance issues or suspect a problem with your fuel system.
