LA 20 is an innovative biological toilet cleaner designed for the effective cleaning and maintenance of toilets and black water systems aboard ships and offshore installations. This product features a specially formulated, moderately acidic, bio-based cleaning chemistry that incorporates both scale prevention and removal technologies.
Ideal for use on en-suites, toilets, sinks, and tiles, LA 20 significantly reduces the buildup of both inorganic and organic scale in wastewater systems while helping to control unpleasant odors.
The active ingredient in LA 20 employs a dual-action antibacterial mechanism and complies with EN1276 standards. It also demonstrates effectiveness against various common viruses, passing the EN14476 test at the recommended usage concentrations.
With LA 20, you can achieve cleaning and sanitizing in one step while simultaneously preventing scale accumulation and reducing inorganic buildup. This eco-friendly toilet cleaner is safe for use and does not harm the beneficial bacteria in sewage treatment systems.
LA 20 is compatible with both vacuum and gravity-fed toilet systems and urinals. Simply apply a small amount of the cleaner around the toilet bowl or urinal surface, allow it to sit for a short period, and then rinse with water.
LA 20 is the preferred choice for biological toilet cleaner by leading OEMs, including G&O Bioreactors.

Overview of ARC 360
ARC 360 is a versatile advanced safe descaling solution designed for various applications on board. This innovative formulation acts as an acid replacement for both manual and cleaning-in-place (CIP) descaling operations, effectively addressing scale buildup in numerous types of equipment, including vacuum toilet pipework, plate heat exchangers, evaporators, coolers, and fresh water generators.
Powerful Degreasing Capability
One of the standout features of ARC 360 is its potent degreasing ability. Unlike other descalers that require a separate degreasing step, ARC 360 can tackle oil and grease contamination simultaneously, streamlining the cleaning process and saving time.

Microclean Plus is a highly effective, water-dilutable cleaner and degreaser designed for use on a wide range of non-porous surfaces found on ships and offshore structures.
It is particularly suited for engine rooms, ancillary equipment rooms, and is highly effective as a machine parts and filter cleaner, as well as a deck cleaner.
This advanced product features a micro-emulsion formulation that blends bio-based surfactants with natural plant extracts. This combination results in a cleaner that not only provides excellent detergency but also has a pseudo-solvent action, making it highly water-dilutable.
Microclean Plus is fully biodegradable, environmentally friendly, and non-corrosive to the skin. It also does not require a UN number classification.
Additionally, its formulation actively reduces the re-deposition of oils during cleaning. Once diluted or left in water (such as bilge or wastewater), the emulsion breaks down, allowing oils to separate cleanly without leaving behind an emulsion layer. This makes it an ideal choice for engine rooms, filters, separators, decks, and fuel oil heaters.
Importantly, Microclean Plus is safe for use in bilge and water tanks, as it does not contain or disrupt any microorganisms in these systems.
GNC Marine offers Microclean Plus in concentrated packaging, which can be easily diluted for use in existing or new cleaning systems.
