Rust or impurities in the fuel can cause damage to the fuel tank, therefore it should not be left untreated.

If your vehicle has been idle for an extended period, gasoline tank cleaning should be undertaken, before you start using it.

Gasoline is used as a fuel for internal combustion engines.

Density of gasoline is between 0.67 to 0.77. It is common to see, that the fuel tank rust from inside, necessitating fuel filters to be changed often.

However, once the cleaning process has been done, the fuel filter will not have to be changed as often.

Gasoline floats on water, therefore gasoline tank cleaning cannot be undertaken with water alone.

Some cleanser in the form of an acid or detergent will have to be added to the water.

A fuel tank is generally made of steel with tin or lead coating on it.

When this comes in contact with oxygenated fuels, they rust and clog the fuel system, which hampers the performance of the vehicle.

Therefore, fuel tank cleaning is then required.

Gasoline Tank Cleaning Procedure

Often for tank cleaning, different acids can be used.

One of the most commonly used acid is the muriatic acid, also known as hydrochloric acid.

Other than hydrochloric acid, phosphoric acid is also often used for tank cleaning purposes.

However, when either of the acid is used one has to take immense amount of care, while undertaking the cleaning procedure.

The other ingredients, which can be used for tank cleaning include vinegar, acetone, detergent, hot water, etc.

It is recommended, that the tank cleaning procedure be undertaken in open air, as the fumes may be hazardous.

With all the primary precautions in place, let's start with the tank cleaning procedure.

Flush out the Contents:

Empty the tank of all its contents.

This is necessary, as without emptying the tank, you will not be able to remove the tank.

Make sure you drain out gasoline from all the components, like rubber hoses, petcock, etc., as well.

Clean the Tank:

Use "fresh" gasoline and clean the tank thoroughly. It is important to use fresh gasoline, as there are chances that the drained out fuel may contain sludge and other impurities.

This is a part of the pre-cleaning process. You can also shake the tank vigorously with gasoline in it.

This will help in dislodging the particles from the farthest corners of the tank.

Then, empty the tank in a separate container.

Cleaning Process:

Just a tip, the cleaning process should be an exhaustive process, so that there are no impurities left in the tank after the cleaning process.

There are different ways which can be used for the actual cleaning process.


The procedures are listed below.

Acetone:

You will need about 2 to 3 quarts of acetone for the process. Close all the holes of the tank using drywall screws.

Pour about 1 quart of acetone into the tank and shake the tank aggressively.

Stop for a small bit and check if the rust is indeed coming out and resume the shaking process.

Empty the acetone out into a sludge bucket and repeat the process.

Vinegar:

Vinegar contains acetic acid, which helps in dissolving the rust from inside the tank. Pour vinegar into the empty tank till its brim.

Close the tank and keep it overnight.

The next morning pour out some quantity of vinegar from the tank and shake the tank vigorously.

Then empty out the contents from the tank. Then pour a little baking soda into the tank and keep it aside for half an hour.

Use water to rinse the tank.

Detergent:

The other method to clean the fuel tank is to use laundry detergent combined with hot boiling water.

Leave the mixture in the tank for an hour or two.

Then pour the mixture out and wash the tank with hot water again.

If you are of the opinion, that the tank is not clean as per your expectations, then you can repeat the process.

Acid:

Muriatic acid or phosphoric acid can be used for the same. Like any other acid, care should be taken while handling muriatic or phosphoric acid as well.

When using muriatic acid, remember to use thick rubber hand-gloves and glasses to protect your eyes from the acid fumes.

Pour hot water in the tank, till it is half full. Add approximately half a gallon of acid to the water.

Then add in the remaining hot water in the tank.

Close the gas tank with a cap, but make sure you do not use the tank cap. Do not disturb the tank for about 2 to 21/2 hours.

Let the entire mixture settle in the tank. Dispose off the mixture from the tank carefully.

Clean with Water:

Now clean the tank with water thoroughly. You can use a hand pump to spray water in the tank.

The pressure of the hand pump will reach to every nook and corner of the tank, thus cleaning it in the process. There can be several rounds of cleaning with water.

Dry the Tank:

The next step is to dry the tank well. You can make use of a hair dryer for the same.

It indeed is a lot of work, but if you leave the tank to dry on its own, it will take longer. There is another advantage of using the hair dryer to dry the tank.

The warm air from the hair dryer will reach well inside the tank in all nooks and corners of the tank.

This is an important step, as gasoline will be filled in the tank soon after the drying process is over.

Gasoline Rinsing:

After you have dried the tank, rinse the tank well with gasoline. It is important, that you make use of fresh gasoline for the same.

It is best not to use the drained gasoline, as it may contain impurities, which may settle inside the tank again. This is the last step in the gasoline tank cleaning procedure.

Fill Gasoline in the Tank:

Attach all the components, which you have removed in the first step. Keep a small quantity of gasoline ready, so that the vehicle reaches the gasoline pump station.

Now, do not waste any time and refill the tank back with gasoline.

It is important to refill immediately, as the tank can start rusting again.

Just a word of caution, wearing protective gear while undertaking the tank cleaning process is important. Make sure no part of the skin is exposed.

Similarly, eye protection gear is also necessary.

Keeping baking soda handy during the cleaning process is recommended, as muriatic acid or phosphoric acid can be neutralized with baking soda.

People have started cleaning their vehicle's fuel tanks as they want to adapt their vehicles to the new mixed biofuel that has hit the market.

Many a time, it is also good to perform gasoline tank cleaning to clean any sludge lodged in the tank, so that the vehicle gives better performance.
