Cleaning Rust From Fuel Tank


Cleaning rust from fuel tanks is a very easy process with Rusted Solutions Soak. The Soak will not damage good paint, is odourless and does not leave a residue behind which will end up in your fuel system.The method varies slightly due to the type of tank being cleaned and also depends on whether the tank can be turned/rotated during the process. The Soak will not damage good metal but it is possible for the rust to have penetrated through the tank already and when the rust is removed the tank can leak so always have something to catch the soak in case this occurs. Dont forget to keep the soak as it will have plenty of rust removing life left in it after the tank is clean


Remove the tank/preparation

Remove any sender units, pickups and stopcocks etc and bung the holes. Give the tank a good flush with degreaser and a pressure washer. This next step is a good one to make the product last longer but is optional. For heavy rust where possible place some large screws in the tank with the degreaser and shake it to assist with dislodging some of the rust and old oil etc (make sure to count the screws before popping them in 🙂 ) Remove the degreaser and save it, flush with water then onto the next step.

Full the tank with "Soak"

The amount of “Soak” required will depend on the size of the tank and whether you can rotate it during the process. Pop in the Soak and let it sit for an hour. Tip the Soak into a bucket or container then flush the lose rust out with water. Rotate the tank (if not full) and repeat as required. Of course being able to just fill it makes the process a lot easier and the product is re-usable so it will have plenty of life left in it after the tank is clean. In some cases there can be old oil trapped in the layers of rust, if you dont notice a considerable change between flushes go back to step one.

Tank is clean

Once the tank is clean dry it. Depending on the type of tank you can use a heat gun (be careful if paint present), give it a shake with fuel or a 50/50 mix of hot water and Metho. If the tank doesnt have a leak fill it with fuel or if storing it pop in some engine oil and rotate the until the inside is covered (that can be removed with a bit of fuel later). Tank liners seem to draw very different opinions from our customers as to their use in the process. We will leave that part up to you.
