How To Clean A Gas Tank On A Lawn Mower

Okay, so your lawn mower's coughing more than your Uncle Jerry after Thanksgiving dinner? Chances are, the poor thing's got a gunked-up gas tank. Let's get that sorted, shall we?
Safety First! (Because Explosions Are Frowned Upon)
Seriously, this is important. We're dealing with gasoline, which, while awesome for starting BBQs, is less awesome when it's going boom where it shouldn't.
Gear Up!
Grab some safety glasses – we don't want any fuel splashing into your peepers. Find some gloves too. Imagine explaining gasoline-soaked hands to your date. Not a great look.
Must Read
Location, Location, Location!
Head outdoors to a well-ventilated area. Think wide open spaces, like your lawn (the one your mower is currently failing to mow). Avoid enclosed garages. No one wants to wake up to a Darwin Award nomination.
The Great Gas Tank Emptying
Now for the fun part, getting rid of that old, yucky fuel. Remember, this stuff is basically liquid bad decisions if handled carelessly.
The Siphon Shuffle
Get yourself a siphon pump. They're cheap, easy to use, and save you from having to do that whole "suck-on-a-hose" thing. Seriously, don't do that.
Insert one end of the siphon into the gas tank and the other into a gasoline-approved container. Think a proper gas can, not your grandma's Tupperware. She'll never forgive you.
Pump away until the tank is drier than a week-old bagel. You're basically giving your mower a much-needed colonic. Pleasant image, right?
Dealing with the Dregs
Even after siphoning, there's usually some sludge hanging around. Think of it as the ghost of lawn mowers past.

Tilt the mower to try and get as much of the remaining fuel out as possible. Have some shop rags handy for the inevitable spills. You're going to need them.
The Big Rinse-Out
Time to evict the remaining crud from its gasoline-soaked apartment.
The Soap Opera (of Fuel Tanks)
Mix up some warm water with a squirt of dish soap. Nothing fancy, Dawn will do just fine. It's the soap that gets the job done, not the brand.
Pour the soapy mixture into the gas tank. Don't be shy; give it a good slosh.
The Shake, Rattle, and Roll
Cap the gas tank (tightly!) and give it a good shake. Think of it as a fuel-tank salsa lesson. Get those particles movin'!
Shake it like you mean it for a minute or two. Now empty the soapy water into a safe container. Again, not grandma's Tupperware.

Rinse and Repeat (If Necessary)
If the water comes out looking like swamp thing just took a bath in it, repeat the soapy water rinse. Keep going until the water runs clear-ish. "ish" is the key word here. Perfection is overrated.
The Drying Game
Moisture is the enemy of engines. Let's banish it.
Air It Out
Leave the gas tank cap off and let it air dry completely. Patience, young grasshopper. This might take a few hours, or even overnight. Think of it as giving your mower's tummy some fresh air.
The Hair Dryer Hack (Optional)
If you're impatient (and who isn't?), you can use a hair dryer on a low setting to speed things up. Just be careful not to melt anything important! Think of it as giving your mower a spa day.
The Finishing Touches
Almost there! Just a few more steps to gasoline-fueled glory.
Inspect and Impress
Give the inside of the gas tank one last look. Make sure it's clean and dry. If you see any lingering debris, fish it out with a clean rag or a pair of tweezers.
The Fuel Filter Fairy
Now's a great time to replace the fuel filter. They're cheap and easy to replace. It's like giving your mower a new pair of lungs (sort of).

Fresh Fuel Fiesta
Fill the gas tank with fresh, clean gasoline. Use the correct octane rating for your mower. Check your owner's manual if you're not sure. Nobody likes a mower with a hangover.
Disposing of the Old Fuel
Don't just dump that old gasoline down the drain! That's bad for the environment and probably illegal. You wouldn't throw a battery in the ocean, would you?
The Responsible Route
Take the old gasoline to a local recycling center or hazardous waste collection site. They'll dispose of it properly. You'll feel good about yourself, and the planet will thank you. High five!
Starting It Up!
Cross your fingers, say a little prayer to the lawn-mower gods, and fire that bad boy up!
Listen for Success
If everything went according to plan, your mower should start up smoothly and run like a champ. You've conquered the gunk and emerged victorious!
If it still coughs and sputters, there might be other issues. But hey, you've already taken a huge step in the right direction. Give yourself a pat on the back!

Preventative Maintenance: Don't Let It Happen Again!
Now that you've gone through all this trouble, let's try to avoid a repeat performance, shall we?
Fuel Stabilizer: Your New Best Friend
Add a fuel stabilizer to your gasoline, especially if you're not going to be using your mower for a while. It's like giving your fuel a bodyguard against gunk and deterioration.
Empty Before Storage
Before storing your mower for the winter, empty the gas tank completely. This prevents the fuel from going stale and gumming up the works. Think of it as putting your mower to bed with an empty tummy.
Regular Tune-Ups: Treat Your Mower Right
Follow the manufacturer's recommendations for regular maintenance, such as changing the oil and spark plugs. A well-maintained mower is a happy mower. And a happy mower means a happy you! Trust me.
Congratulations!
You've successfully cleaned your lawn mower's gas tank. You're basically a lawn-care ninja now. Go forth and conquer that grass!
And remember, a little preventative maintenance goes a long way. Now go enjoy that perfectly manicured lawn (that you earned)!
You are now one step closer to lawn care mastery.
