Step 1. Disconnect the tank

Before doing anything, you should take the trouble to disconnect the tank from the motorcycle or any other machine. If you don't, you won't be able to access or clean the room safely. It is therefore important that you can disconnect the tank and unscrew the screws or bolts that hold it in place.

  • Be aware that you need to remove the spark plug and fuel line when dealing with lawn mowers or similar attachments.
  • For motorcycles, remove the fuel cap, the drain valve and any hoses that may be attached to it.

  • Take a smooth-sided clamp and attach it to the fuel line near the carburetor.
  • Separate the carburetor and fuel line.
  • Put the fuel line over a bucket and remove the clamp.
  • Allow the contents of the line to drain into the bucket.

  • Keep in mind that you will not be able to clean the tank properly if you do not drain the remaining fuel. In addition, you need to make sure that there is no fuel left in the tank.

It is important that you can take the time to carefully examine the tank for any issues that could compromise its integrity. For example, rust, defects or the like can pose potential accident hazards or damage the engine.

  • You should pay special attention to wear, defects in the material of the tank or rust spots.
  • Take the trouble to examine the fuel filter to make sure it is clean. If not, then it should be replaced.

After removing the tank, you must then completely empty it of any fuel that may still remain in it. The extent of this process may depend on the condition and type of the tank, or the amount of fuel left in it. To empty your vehicle's tank there are a number of things you can do.

  • Use a suction device to be able to transfer the fuel to a storage container.

You may need to degrease your fuel tank if you notice that there is still the smell of gasoline coming out after emptying it. Be aware that you will get better results by degreasing the tank.

  • You can use a degreaser like Marine Clean.
  • Make an effort to mix hot water with dish soap.
  • Leave the soap and water solution or degreaser in the tank for up to 24 hours.
  • If the soap solution or the degreaser does not give the desired result after the 24 hour period, then consider degreasing your vehicle's tank again for a longer period.

Step 5. Clean the pressure tank

You will need to take a pressure washer and spray the inside of the tank after removing it from the car. This action will allow you to remove debris, dirt and small flakes of rust and rinse the fuel deposit.

  • It is recommended that you use a regular garden hose and a spray bottle or pressure washer to clean the inside of the tank.
  • You may need to orient the sprayer at different angles to be able to remove any light rust and other build-up of deposits that may be inside the tank.

Step 6. Use a cleaning solution

If there is a significant amount of rust or dirt inside the tank, be aware that you will need to use commercial solutions to remove it. These solutions work by chemically breaking down rust. This will allow you to easily rinse and remove the debris that is inside your tank after using them.

  • Choose quality acid solutions that will dissolve rust in a tank.
  • Keep in mind that cleaning solutions should only be applied to tanks that have not been used for a long time.

Step 7. Rinse the tank

After using the cleaning solution or even a degreaser (like a mild soap), you should rinse the tank several times so that the soap or foam residue is completely removed. Be aware that you risk damaging your vehicle's engine if you do not remove all chemical residue from the tank.

  • Remember that you must empty the tank and refill it to be able to remove the other debris that remained there after removing the accumulations of rust and deposit.
  • Take the trouble to rinse the tank until there are no more foams or bubbles in the water. You may be required to do this 2-3 times.
