Cleaning the inside of a gas tank is not as difficult as it may seem. There are a few things that you will need to get the job done.

First, you will need to gather some supplies. You will need a funnel, a clean rag, and some type of cleaning solution.

We would recommend using either white vinegar or baking soda mixed with water. Once you have your supplies, begin by attaching the funnel to the opening of the gas tank.

Pour your chosen cleaning solution into the tank until it is about half full. Then, take the clean rag and stuff it into the tank, so it is saturated with the solution.

Use your hand to swish the rag around the tank’s inside, ensuring all surfaces are covered. Let the solution sit inside the gas tank for at least an hour before draining it out.

Once you have drained all the solutions, rinse the tank with fresh water a few times to remove any residual cleaner. Allow the gas tank to dry completely before adding fresh gasoline.

Will Seafoam Clean a Gas Tank?

If you’re looking to clean your gas tank, you may wonder if seafoam is a good option. While it’s true that seafoam can help to clean and lubricate your engine, there are better choices for cleaning a gas tank. There are a few reasons why:

  • Seafoam is designed for use in an engine, not a gas tank. Using it in a gas tank could damage or even break the fuel pump.
  • It contains chemicals that could potentially corrode the inside of your gas tank. Over time, this could lead to leaks or other problems.
  • If any seafoam gets into your fuel lines, it could clog up your fuel filter or cause other issues further down the line.


So, you now know how to clean a gas tank without removing it. Cleaning a gas tank without removing it can be done safely and effectively with the right supplies and processes.

By following the proper steps and using the right cleaning materials, you can ensure that your gas tank is free of contaminants and ready to use. With this knowledge, you can now confidently keep your gas tank clean without taking it out.
