Step-by-Step Guide for Cleaning the Gas Tank
Step 1: Safety First
Make sure the mower is turned off and cooled down. Disconnect the spark plug wire to prevent accidental starting. Wear gloves and safety glasses for protection during cleaning.
Step 2: Drain the Old Fuel
Remove the fuel cap and carefully pour the remaining fuel into a suitable container. Using a siphon or a pump can make this process easier. Properly dispose of the old fuel according to local regulations.
Step 3: Remove the Gas Tank
Locate the screws or bolts holding the tank in place. Use screwdrivers or pliers to detach the tank carefully. Take note of how the tank is attached for reassembly.

Step 5: Clean Inside the Tank
Mix a cleaning solution using equal parts vinegar and water or buy a commercial gas tank cleaner. Pour the mixture into the tank and swirl gently. Let it sit for about 30 minutes to loosen gunk.
Step 6: Scrub the Interior
Use a soft brush or old toothbrush to gently scrub the inside walls. Focus on areas with stubborn residue. Avoid scratching the tank surface as it can cause leaks.
