What is the difference between fuel filtration and fuel polishing? Fuel filtration (as the one that is fitted on your boat and engine) uses filters that remove free water (the water that accumulates at the bottom of the tank) and particle contamination (rust, dirt etc) to a certain size usually 30 micron for conventional diesel engines. HPCR diesel engines (High Pressure Common Rail) require higher levels of filtration usually 2 micron. Fuel polishing removes what fuel conventional fuel filtering is not usually capable of (emulsified water and microbial contamination, diesel bug). We use our own technology to efficiently clean all the contamination from your diesel fuel.

We have developed the most innovative 7 STAGES diesel fuel polishing service in the industry designed to leave your tanks free of water, debris and microbial contamination (also known as algae, diesel bug or diesel fungus). No other technology available today comes even close. We guarantee to remove all the debris, water and microbial contamination. leaving your diesel tank to as new condition in just a few hours.

STAGE 1: Ultrasonic or Vacupower dislocation of sludge from the bottom and walls of the tank. (Good access to all baffled sections needed for best results) 

STAGE 2: Sludge separation and cyclone filtration 25 micron.

STAGE 3: Centrifugal free water separation (water accumulated at the bottom of the tank usually has an acid PH of around 5.5 that will increase the corrosion rate of metal tanks).

STAGE 4: 10 micron particulate filtration.

STAGE 5: Emulsified water separation 10 micron (fuels can contain up to 15% water in emulsified state).

STAGE 6: Ultrafine 5 micron (optional 2, 1 and 0.5 micron for common rail engines) particulate filtration.

STAGE 7:  UV with proprietary wave lenght modulation and ultrasonic cell disruption exposure for effective kill of 100% microbial contamination.


With the tank and diesel decontaminated you can keep it clean by using diesel biocides and additives that work better when the sludge is not present.

IMPORTANT: We recommend that after every diesel tank cleaning/diesel fuel polishing procedure you replace primary and secondary filters on your boat to ensure a 100% clean fuel system.
