Drain the tank
Before you begin to drain the tank, it is important to disconnect the tank from the quad or other machinery. You won't be able to access it or clean it safely if you don't. Unstrap the tank and unscrew any screws or bolts that secure it. Make sure you are not directly below the tank when disconnecting it.
Now, you can begin to drain the tank. Use a suction device to transfer the gasoline into a storage container. If there is some liquid that you still can't remove, turn the tank upside down and let it drain into a container. You may find that sludge or other debris will come out with the remaining gasoline. It is important to dispose of the gasoline appropriately. If you don't, you may contaminate the groundwater in your community. Store gasoline in approved containers and contact your local waste disposal service to find out where you can dispose of your gasoline.
If the fuel is old or rancid, dispose of it safely. If not, preserve it in a gas can or an appropriate fuel container. If the tank has cracks or small holes, seal them using rubber or vinyl vacuum caps.
If you are cleaning the tank because of incidental dirt entering during the fueling process, ensure the fuel container and the tank on your quad remain clean and free of dirt or dust.

Clean with detergent and water
To clean a quad fuel tank with detergent and water, you'll first need to drain the tank of any fuel. This can be done by using a suction device to transfer the gasoline into a storage container, or by turning the tank upside down and letting it drain into a container. Once the tank is empty, you'll need to mix a solution of hot water and detergent. This can be regular dish detergent, or a specialised degreaser. Pour the solution into the tank and let it sit for at least 24 hours.
After the detergent and water solution has had time to work, you can begin rinsing the tank. Use high-pressure water to rinse the tank, and repeat this process until there are no more bubbles or foam. If possible, use a brush to loosen any remaining debris from the sides of the tank. It is important to ensure that all detergent is rinsed out, as you do not want any soapy water mixing with your fuel.
Once the tank is rinsed, use a lint-free cloth to wipe down the outside and apertures, removing any remaining moisture. Then, leave the tank to dry completely. This may take 24-48 hours. It is important that the tank is completely dry before refilling it with fuel, as any water left in the tank can damage your engine or fuel system.
