Diesel Fuel Polishing & Tank Cleaning Services
Protect your fuel. Protect your equipment. Nationwide service for critical facilities.
Diesel Fuel Polishing at Critical Facilities
In mission-critical facilities like hospitals, data centers, and military bases, reliable backup power is essential. Diesel fuel powers emergency generators so that these facilities can continue operating during power outages. But, without proper maintenance, stored diesel fuel can become contaminated, risking system failures when they are needed most.
PFP makes maintaining diesel fuel for essential facilities easy. Our highly-skilled technicians will arrive to your facility with all of the equipment necessary for performing a full-service diesel fuel polishing and tank cleaning job.
Contact us today to learn how PFP’s mobile fuel polishing solutions can save you time, reduce fuel waste, and keep your systems running at peak performance.
Fuel Tank Cleaning Services
Diesel storage tanks are often out of sight and out of mind — until contamination turns into a costly problem. Over time, water, sediment, and other harmful contaminants collect at the bottom of tanks, creating sludge that degrades fuel quality and threatens the reliability of your equipment & backup power systems.
Our professional tank cleaning services tackle this hidden risk head-on. We use proven methods to safely remove all forms of contamination, restoring your tanks to optimal condition. When combined with diesel fuel polishing, you’re guaranteed clean fuel from the tank floor all the way to your equipment.
Meet ASTM D975 fuel specs, protect your equipment, and rest easy knowing your diesel is ready for use — no surprises.
See the Difference. Keep your diesel clean.
The difference is clear — literally. Untreated diesel fuel turns dark and cloudy when loaded with contaminants that can shut down your equipment and backup power systems.
Our before & after samples demonstrate just how much you stand to gain from routine fuel maintenance services. Clean, polished fuel doesn’t just look better – it protects your equipment and keeps you compliant.
One call keeps your diesel fuel clean, your tanks protected, and your mind at peace.

FAQ’s
What is diesel fuel polishing and why is it necessary?
Diesel fuel polishing is a filtration process that removes water, particulate contamination, microbial growth, and degradation byproducts from stored diesel fuel. Over time, stored fuel naturally absorbs moisture and supports microbial growth, which can lead to clogged filters, injector damage, corrosion, and equipment failure. Polishing restores fuel quality and helps ensure reliable engine and generator operation.
How often should diesel fuel storage tanks be cleaned or polished?
The required frequency depends on storage conditions, fuel turnover, and environmental exposure. Many facilities schedule fuel polishing annually or semi-annually, while backup generator tanks may require more frequent service due to long storage periods. Regular testing and inspection help determine when polishing or tank cleaning is necessary to prevent operational issues.
What contaminants are removed during diesel fuel polishing?
Fuel polishing removes free and emulsified water, sediment, rust, microbial contamination (diesel bugs), and oxidation byproducts. These contaminants can cause fuel instability, filter plugging, reduced combustion efficiency, and premature wear of engines and fuel system components if left untreated.
Can diesel fuel polishing be performed without shutting down equipment?
In many cases, yes. Fuel polishing can often be performed while tanks remain in service, depending on system design and operational requirements. PFP evaluates each application to determine the safest and least disruptive approach, minimizing downtime while maintaining fuel system integrity.
What is involved in diesel fuel tank cleaning services?
Tank cleaning goes beyond filtration by removing sludge, biological growth, and debris that settle on tank bottoms and internal surfaces. The process may include fuel transfer, internal cleaning, waste removal, and proper disposal of contaminated materials. Tank cleaning is typically recommended when heavy contamination is present or during major maintenance events.
Why is fuel polishing important for emergency generators and backup power systems?
Emergency generators often rely on stored diesel fuel that may sit unused for extended periods. Contaminated fuel is a leading cause of generator failure during outages. Regular fuel polishing and tank cleaning help ensure backup power systems start reliably when needed, protecting critical operations such as data centers, hospitals, and industrial facilities.
