Fuel polishing and tank cleaning
Not all Cleaning Systems are the same.

Modern day diesel has undergone significant changes to meet stricter environmental regulations, these changes have introduced new challenges for fuel maintenance and way we deal with these issues.

Clean Fuel Marine has adapted our equipment to these changes and the way we clean your tank and fuel.

Many fuel polishing systems remove much of the water build up in the bottom of your tank and diesel bug itself, but leaves water saturated in your fuel and other contamination behind in the bottom of your Fuel tank.

We're on T.V

Last year channel 4 approached us about being on series 2 of Narrow Escapes.
We cleaned the Angry Boaters fuel and tank in preparation for Gloucester pilots to take him and his boat down the river severn.

We’re on Episode 24 on Season 2 It’s available on line

Jason was very helpful and did an excellent job even surviving a thunderstorm. It was a job that definitely needed doing, badly, but he stuck at it and now we are good to go! Highly recommended. Thanks Jason & co

Clean Fuel Marine did a great job of cleaning the diesel and tank on my 55ft Narrowboat "Reality." Communication was easy and clear, they turned up on time, had all the right equipment and did a very careful and thorough job with very clear explanations of what they were doing. I wouldn't hesitate to use Jason and Joe again, a very pleasant experience.

Clear explanation of the process over the phone and once agreed was very quick to attend the boat and complete the process. Spent time at the boat helping with a couple of other minor issues. Jason and Joe were polite and courteous. Excellent job all around.

Father & Son, plus tea and biscuits plus 3 hours of solid work! Both carried out the work with no complains except when I was late with the tea and biscuits, dad only. The tank was a 300ltr fuel tank at the back of the Narrow Boat. All equipment used was in good condition and all debris was taken away and I was left with a sample bottle of the fuel cleaned as well as a certificate to confirm that the tank had been cleaned.
