Step 1

You will first need to open the drainage valve so that you can drain the fuel oil tank of any excess oil. Before you do begin draining the oil tank, you should get a large container to catch all the oil and fluid which is coming from the tank.

Step 2

You should then spray the inside of the tank with a water hose, you should let the water drain out. You should continue spraying the inside of the tank until the water is completely clear.

Step 3

You should then replace the drainage cap on the fuel tank. Once you have replaced the cap you should then open the main filler. You will then have to fill the tank with a cleaning solution and water mix; this is the main part of the oil tank cleaning.

Step 4

If you then place the air hose into the main filler and keep pushing the air hose into the tank until it hits the bottom. You should leave the air pump on overnight, this way the cleaning solution can thoroughly clean the entire tank.

Step 5

Once the cleaning solution has been left overnight, you should then drain it out.

Step 6

It is important that you then dry the tank, to do this you should pour in the correct amount of denatured alcohol into the tank. You should try and cover as much of the surface as possible with the denatured alcohol as this will absorb the water.

Step 7

You should then use the air hose to blow air into the tank which will then dry it out.
