Are you tired of dealing with a sputtering, sluggish lawn mower? Is your lawn mower’s gas tank a murky mess of old gasoline and grime? Cleaning your lawn mower’s gas tank might seem daunting, but it’s a surprisingly simple and effective way to breathe new life into your trusty machine. This comprehensive guide will walk you through the steps of cleaning a metal gas tank, from removing it from the mower to getting rid of stubborn residue. By the end, you’ll be able to tackle this task with confidence and get your mower running smoothly again.
Why Clean Your Lawn Mower Gas Tank?
Cleaning your lawn mower’s gas tank is essential for several reasons. Firstly, old gasoline can leave behind varnish and gum that clogs fuel lines and carburetor jets, leading to a decrease in performance. Secondly, water can accumulate in the tank, causing rust and corrosion. This can eventually lead to leaks and even damage to the entire fuel system. Finally, a clean tank ensures that the fuel mixture is consistently delivered to the engine, resulting in smoother operation and better performance.
Getting Started: Preparation and Safety
Before embarking on the cleaning process, ensure you have the necessary tools and materials, and prioritize safety:
1. Gather your Supplies:
- Safety Glasses: Protect your eyes from splashes and fumes.
- Gloves: Protect your hands from the chemicals.
- Work Area: Choose a well-ventilated area, preferably outdoors.
- Tools:
- Screwdriver (for removing the tank)
- Wrench (for removing the tank)
- Rags
- Funnel
- Container for draining fuel
- Cleaning Supplies:
- Gasoline or mineral spirits
- Non-toxic cleaning solution (optional)
- Compressed air (optional)
2. Safety First:
- Turn off the mower and disconnect the spark plug. This ensures the engine cannot start accidentally.
- Allow the engine to cool down completely. A hot engine can cause burns.
- Work in a well-ventilated area. Gasoline fumes are flammable and harmful.
- Keep children and pets away from the work area.
3. Drain the Tank:
- Find the fuel valve or petcock. It’s usually located at the bottom of the gas tank.
- Place a suitable container under the valve.
- Open the valve and allow the gasoline to drain completely.
- Dispose of the drained fuel properly. Do not pour it down the drain, as it can contaminate water sources.
Cleaning Your Metal Gas Tank: The Steps
Once the fuel has been drained and the tank is empty, you can begin the cleaning process:
1. Remove the Gas Tank:
- Locate the tank. It’s usually positioned near the engine.
- Identify the mounting points. There might be screws, bolts, or clamps holding the tank in place.
- Carefully remove the tank. Take your time to avoid damaging any parts.
2. Thorough Cleaning Inside and Out:
- Rinse the tank. Flush out the tank with gasoline or mineral spirits. Swirl the solution around the tank to dislodge any debris or sediment.
- Scrubbing and removing debris. If you encounter stubborn buildup, use a non-abrasive cleaning cloth or a soft brush to scrub the inside of the tank.
- Rinse again. Repeat the rinsing process with gasoline or mineral spirits until the inside of the tank is clean.
- Dry the tank. Use a clean cloth to dry the inside and outside of the tank thoroughly. Allow the tank to air dry completely.
3. Dealing with Rust:
- Examine the tank. If you find rust, you’ll need to address it.
- Remove loose rust. Use a wire brush, sandpaper, or a rust remover to remove loose rust particles.
- Coat the tank. Apply a rust-preventive coating to protect the tank from further corrosion. You can use a commercially available rust-inhibiting paint, or a simple solution of vinegar and baking soda.
4. Using Compressed Air (Optional):
- Remove stubborn sediment. If you have access to compressed air, use it to blow out any remaining debris. Be careful not to damage the tank with excessive pressure.
- Drying. Use the air to ensure the tank is completely dry before reassembling.
Final Touches and Reassembly:
1. Reinstall the Tank:
- Ensure it’s clean and dry. Check the inside and outside of the tank for any remaining debris or moisture.
- Reattach the tank. Carefully return the tank to its original position and secure it using the mounting points.
2. Final Inspection and Testing:
- Visually inspect the tank. Make sure there are no leaks or damage.
- Test the fuel system. Reconnect the spark plug and fuel lines. Fill the tank with fresh gasoline and start the engine to check for proper fuel flow.
3. Maintenance Tips:
- Regular Cleaning. Clean your lawn mower gas tank every 6-12 months to prevent the buildup of debris and residue.
- Use Fresh Gasoline. Old gasoline can degrade and cause engine problems. Use fresh gasoline and store it in a sealed container to prevent evaporation.
- Proper Storage. During the off-season, drain the gas tank completely and run the engine for a few minutes to burn off any remaining fuel.
