How do you remove trash from a lawn mower gas tank?

To remove trash from a lawn mower gas tank, first ensure the mower is turned off and cooled down. Use a siphon pump or a turkey baster to carefully extract the fuel, then inspect the tank for debris. If accessible, use a soft cloth or a small brush to clean out any residue. Finally, refill the tank with fresh fuel and check for any remaining contaminants before restarting the mower.
