Fuel Polishing & Tank Cleaning

Contaminated diesel is one of the leading causes of engine failure in yachts and motorboats. The problem usually begins when water enters the fuel tank - through condensation, poor-quality fuel, or minor leaks. Once water is present, it creates the perfect environment for diesel bug (Cladosporium Resinae) to grow.

Over time, this contamination can cause:

Sludge buildup in the tank
Blocked fuel filters
Carbon deposits in injectors
Engine failure or power loss
Internal corrosion of the fuel tank

As algae, waxes, and natural fuel residues accumulate, performance drops and the risk of breakdown increases - often at the worst possible moment.
