Diesel Fuel Tank Maintenance

Using Jewelers' Rouge to Keep a Fuel Tank Polished

  • Use a 6-8" diameter muslin wheel
  • The higher speed on the wheel the better (10,000 RPM is good)
  • Be generous with the jewelers' rouge
  • Use the exterior edge of the wheel
  • Buff an area no larger than the size of your hand at one time.
  • Get it looking perfect, then move on.
  • There will be black goop on the surface of the tank. Remove this with acetone, lacquer thinner, or baking soda and a rag.

Removing Bacteria from Fuel Tanks

  1. Remove fuel tank and drain off fuel
  2. Partially fill tank with high concentrations of simple green (high-alkaline solution) or the chemical: Sodium Tripolyphosphate
  3. Agitate for 30 to 60 minutes
  4. Rinse well with water
  5. Rinse well with a mild bleach solution to neutralize the alkalinity
  6. Rinse well with water

Note: Fuel can be treated with a biocide treatment to prevent future contamination.
