Clear-Diesel Fuel & Tank Cleaner

An advanced diesel fuel and tank cleaner.

The Fuel Polishing Formula of Clear-Diesel Fuel & Tank Cleaner removes water and slime, disperses contaminants and stabilizes fuel during long-term storage.





Available in: 16-Ounce, 32-Ounce, 80-Ounce, 1-Gallon, 2.5-Gallon, 55-Gallon Drum


Clear-Diesel Fuel & Tank Cleaner is an advanced diesel fuel and tank cleaning technology. Water has always been a problem in diesel fuel. But today’s cleaner-burning fuels have dramatically reduced sulfur content and are more prone to water separation, contamination and are inherently unstable. This Fuel Polishing Formula removes water and slime, disperses fuel contaminants and stabilizes fuel during long-term storage. It can be used as a vital part of any preventive maintenance program or for immediate clean-up of equipment or fuel storage tanks. Add Clear-Diesel at least quarterly or as needed.

Benefits

  • Disperses diesel fuel contaminants
  • Removes water and slime
  • +Petrofresh provides maximum long-term storage stability – keeps fuel fresh
  • Prevents premature fuel-filter plugging
  • Protects against fuel tank corrosion
  • Effective in conjunction with Bio Kleen Diesel Fuel Biocide to remove residual water and contaminants during microbial contamination clean-ups
  • Effective in all diesel fuels, including Ultra Low Sulfur Diesel (ULSD), biodiesel and biodiesel blends
  • Does not contain alcohol of any kind
  • Safe for use in all diesel engines
  • Will not void engine manufacturer's warranty when used as directed

Clear diesel did an excellent job after having 2 years of problems but its hard to find.

Robert Scott

Truck began hesitating on acceleration and I found low amounts of water in my water separator. I used clear diesel and it cleared up the hesitation and my truck ran great! Awesome product along with your diesel kleen (which I already use).

Ron Strecker

Clear-Diesel is awesome.. Great job keeping water out.. But its hard to find.. Bio Diesel sucks..

Voice of the Customer

I bought the truck in Minnesota in February at an auction from the military. The vehicles sit a lot and it was cold and hard to start. It ran ok but didn’t seem to have good power. I stopped at the first truck stop to fuel up and find some additives for the fuel. Luckily I bought Diesel Kleen. With in a quarter tank it was running smoother and had better power. I drove it all the way home to Washington state. I now use it in my Ford 7.3 and an older diesel army truck. They all run great. Thanks for a great product!
