Fuel polishing for stored fuels

Typically, this contamination consists of particulate matter, free-standing water and sludge.

What is fuel polishing?

Fuel polishing is a mechanical cleaning process used to remove harmful chemicals or bacteria in the fuel.


Fuel is removed from the tank, passed through specialist equipment and then filtered back through resulting in clean fuel.
