Is your lawn mower sputtering and coughing, refusing to start smoothly? Perhaps you’re struggling with inconsistent performance, even after filling up with fresh fuel. The culprit might be a dirty gas tank, a common issue that can plague even the most well-maintained lawnmowers. This article will guide you through the process of cleaning your gas tank, from understanding the reasons behind the grime to the steps involved in restoring it to pristine condition. We’ll cover everything from identifying the signs of a dirty tank to the essential tools and techniques, empowering you to tackle this maintenance task with confidence.
Overview
A dirty gas tank can lead to several problems, including:
- Fuel starvation: Sediment and debris can clog fuel lines and restrict fuel flow, leading to inconsistent engine performance.
- Engine sputtering: Contaminated fuel can lead to misfires and uneven engine operation.
- Difficult starting: A dirty gas tank can make it challenging to get your lawnmower started.
- Premature wear: Contaminated fuel can contribute to wear and tear on engine components.
Fortunately, cleaning your gas tank is a relatively simple process that can significantly improve your lawnmower’s performance and longevity.
Why Does Your Gas Tank Get Dirty?
Understanding the Sources of Contamination
While it might seem counterintuitive, even high-quality gasoline can harbor contaminants that accumulate over time. These contaminants can originate from several sources:
- Condensation: Moisture can condense inside the gas tank, particularly in humid environments, leading to the formation of rust and sediment.
- Fuel Additives: Some fuel additives can break down or separate over time, leaving behind residues in the tank.
- Ethanol: Ethanol, a common component of gasoline, can absorb moisture, contributing to the formation of sediment and rust.
- Dirt and Debris: Dust, dirt, and other particles can enter the gas tank through the filler neck, especially when refueling in dusty environments.
Recognizing the Signs of a Dirty Tank
Here are some key indicators that your lawnmower’s gas tank might be in need of a cleaning:
- Difficult starting: If your lawnmower struggles to start or requires multiple attempts, a dirty tank could be the culprit.
- Sputtering and coughing: An engine that sputters or coughs intermittently, particularly under load, often points to fuel delivery issues related to a dirty tank.
- Loss of power: If your lawnmower seems to lack power or struggles to maintain speed, a clogged fuel system may be hindering fuel flow.
- Uneven engine operation: A dirty tank can contribute to uneven engine operation, resulting in rough idling or inconsistent performance.
If you observe any of these symptoms, it’s advisable to check and clean your gas tank.
Gather Your Supplies
Before embarking on the cleaning process, gather the necessary tools and materials:
- Safety Glasses: Always protect your eyes when working with gasoline and cleaning agents.

- Bucket: Use a bucket to hold the cleaning solution and rinse water.
- Shop Towels: Have plenty of shop towels on hand for cleaning and drying.
- Funnel: A funnel will help you safely pour the cleaning solution and rinse water.
- Phillips Screwdriver: You may need a screwdriver to remove screws holding the gas tank in place.
- Wrench: A wrench is necessary for loosening and tightening bolts.
- Gasoline-Resistant Container: Use a gasoline-resistant container to store the contaminated cleaning solution.
