Fertan Concentrated Rust Remover – 1L

If you have a petrol tank with rust inside this is what you need!

Before sealing any petrol tank with Flowliner Tank Sealer, we always like to de rust and make the inside of the tank like brand new with the Fertan Rust Remover. We recommend using the whole bottle in a tank filled to the top with boiling water which we leave for around 8 hours.

Once you have drained the Fertan out of your tank (pour it in a bucket so you can continue to use the solution to de rust nuts, bolts etc), it is very important to dry the inside of your tank thoroughly with a hair dryer or a hot air gun, this will stop the bare metal from flash rusting.

FeDOX Rust Remover (Concentrated) is specially developed for de-rusting of steel parts and inner tank surfaces.

FeDOX can be diluted in water, with a maximum dilution ratio of 1:10. The parts to be derusted are then immersed in the solution.
The solution can be heated up to 65°C for faster derusting.
The duration of derusting varies depending on the thickness of the parts.
Flash rust is removed within 15-45 minutes while a thicker layer of rust takes up to 12-24 hours of time.
Post derusting the components should be washed with water and coated thereafter immediately with any kind of waxes (ex. Protewax) or primers (ex. FERPOX Epoxy Primer or MM30 Multi Metal Coating).
