Engine room cleaning products for ships and vessels
Biological engine room cleaners and degreasers that remove oil and grease without compromising oily water separators or discharge compliance.
Why engine rooms need OWS-compatible cleaners
Engine room cleaning is critical to safe, efficient ship operation - but traditional marine degreasers and bilge cleaners can create downstream issues.
High-emulsifying surfactants and aggressive solvents can disrupt oily water separation, increase waste retention and place additional strain on onboard treatment systems.
Biotal Marine engine room cleaners are formulated to remove oils, grease and ingrained contamination while supporting system performance. Using eco-benign® chemistry and controlled-emulsion technology, they clean bilges, machinery and engine room surfaces without creating stable emulsions that interfere with oily water separators (OWS).
By working with onboard systems rather than against them, these cleaners help maintain efficient OWS separation, reduce oily waste volumes and support compliance with MARPOL Annex I discharge requirements.
Designed for OWS performance and MARPOL compliance
The problem
Traditional cleaners can fail OWS
Many marine degreasers and bilge cleaners form stable emulsions that pass straight through oily water separators without breaking. Oil-in-water content rises, alarms trigger, and what should be a routine cleaning job ends up risking compliance with MARPOL Annex I.
The Biotal approach
Cleaning that separates cleanly
Biotal Marine engine room cleaners use controlled-emulsion technology, lifting oil and grease during the clean but allowing rapid separation downstream. The result is effective cleaning of bilges, machinery and engine room surfaces without compromising the OWS that has to process the wastewater.
The result
Cleaner bilges, compliant discharge
Oily water separators continue to function as designed, oil content monitor (OCM) readings stay within limits, and discharge meets MARPOL Annex I requirements. Engine room teams clean confidently, port state inspections pass without findings, and oily waste volumes stay manageable.

Our environmentally responsible formulations are award-winning
Sustainability matters
Not all bacteria are equal
We select specific bacterial strains for each application, focusing on performance and environmental compatibility rather than generic biology.
Fermented & processed in our own facility
Producing our biology in-house gives us full control over quality, consistency and environmental standards at every stage.
Scientifically validated, verified strains
Each strain is researched, tested and proven for its intended use, ensuring reliable performance without unnecessary environmental impact.
Gentle on marine life and underwater environments
Our formulations are designed to minimise toxicity beyond oil reduction alone, helping protect marine life and support healthier underwater ecosystems.
