RXSOL BTC ZYME
Biological Toilet Cleaner for Marine Sanitary & Sewage Treatment Systems
RXSOL BTC ZYME is a biologically active liquid cleaner designed for use in marine toilets, sanitary systems, sewage lines and sewage-treatment systems. It combines specialized bacterial activity with biodegradable, low-foaming cleaning agents and anti-foam components to support effective cleaning while maintaining biological activity within the sewage system.
The biological action helps break down organic deposits, grease, fats, starch, faecal matter, paper residues, proteins and other biodegradable waste materials that can accumulate in sanitary pipework and toilet systems.
RXSOL BTC ZYME is particularly suitable where conventional aggressive toilet cleaners may interfere with the natural biological activity required for effective sewage treatment.
RXSOL Zyme BTC is a unique biological active liquid formulation containing specialized bacterial strains, biodegradable low foaming chemical cleaners and anti foam agents.
How it works
RXSOL Zyme is specifically formulated to replace aggressive, toxic toilet cleaners that can disable the sewage treatment plant by killing the naturally occurring bacteria that are essential to its operation. Conventional toilet cleaners may also cause foaming in the vacuum inductor which destroys the vacuum in the sanitary flushing system. RXSOL Zyme BTC effectively cleans the toilets and doses millions of selected safe bacteria into the sanitary system. These powerful specialized bacteria colonies the organic waste lining the pipe system and remove the organic deposit. On draining to the sewage treatment plant, the bacteria will enhance the biological activity, reducing solids and odors. Grease, fats, starch and other organic compounds are digested by Rxsol Zyme BTC. The degradation of paper, protein, waste product residuals and other odorous materials is also enhanced. RXSOL Zyme BTC cleans more thoroughly and deeply compared to conventional cleaning products. The use of cleaning products containing hazardous chemicals such as acids, caustics, bleaches, disinfectants, etc., can be reduced.

Directions for Use and Dose Rates
Use RXSOL Zyme BTC daily as a normal toilet cleaner. Lift up seat, open the bottle and direct nozzle downwards. Squeeze and direct the jet to adequately cover the surface of the toilet bowl. After some minutes scrub vigorously with a toilet brush and flush with water. For removal of water scale, uric acid and rust stains, use RXSOL Zyme Toilet Descaler. See product data sheet. For heavy soil pipes dose RXSOL Zyme DPC to initiate the cleaning process and continue with RXSOL Zyme BTC. See also product data sheet for RXSOL Zyme DPC. The use of toilet cleaners containing toxic ingredients as acids, disinfectants, bleaches, etc., will have a detrimental effect on the biological activity and should not be used with RXSOL Zyme BTC.
How RXSOL BTC ZYME Works
RXSOL BTC ZYME introduces selected beneficial bacterial activity into the sanitary system. These microorganisms can act on organic deposits accumulated inside toilet and sanitary pipework.
The biological action helps break down:
-
Faecal matter
-
Grease and fats
-
Starch
-
Organic waste
-
Paper residues
-
Protein residues
-
Other biodegradable deposits
As organic material is degraded, the treatment can help reduce the accumulation of solids and unpleasant odours within the sanitary system.
The biological activity also supports the downstream sewage-treatment process by contributing to the biodegradation of organic matter. (Wilhelmsen)
Marine Applications
RXSOL BTC ZYME is intended for suitable marine sanitary and sewage applications, including:
Shipboard Toilets
For routine cleaning and maintenance of marine toilet bowls and sanitary fixtures.
Sanitary Pipe Systems
Helps manage organic deposits that accumulate within sanitary pipework.
Sewage Treatment Systems
Suitable for vessels where maintaining biological activity in the sewage-treatment system is important.
Accommodation Areas
Can be used for toilets, sinks, showers and related sanitary areas where biodegradable biological cleaning is required.

Typical Toilet Cleaning Procedure
For routine toilet cleaning:
-
Open or lift the toilet seat.
-
Apply RXSOL BTC ZYME onto the internal toilet-bowl surface.
-
Ensure adequate coverage of the contaminated surface.
-
Allow a short contact period.
-
Scrub the bowl thoroughly using a toilet brush.
-
Flush with water.
The reference manufacturer's instructions specify daily use as a normal toilet cleaner, with application directly to the toilet bowl followed by scrubbing and flushing.
Important: Descaling & Rust Removal
RXSOL BTC ZYME is primarily intended for biological cleaning and organic-waste degradation.
For deposits such as:
-
Water scale
-
Uric acid scale
-
Rust stains
-
Hard mineral deposits
a dedicated toilet descaler or appropriate scale-removal product should be used rather than relying on BTC ZYME alone. The reference product instructions likewise distinguish descaling from the biological toilet-cleaning function.
Heavy Soil in Sanitary Pipes
Where sanitary pipes contain heavy organic contamination or significant soil deposits, an initial treatment using an appropriate heavy-duty biological pipe-cleaning product may be required before continuing with routine BTC ZYME treatment.
Chemicals to Avoid
To preserve biological activity, avoid using BTC ZYME together with aggressive toilet cleaners containing:
-
Strong acids
-
Bleaches
-
Disinfectants
-
Strong caustic cleaners
-
Other chemicals that can kill or inhibit beneficial bacteria
NOTE: specifically warns that toxic acid, disinfectant and bleach-based toilet cleaners can have a detrimental effect on the biological activity of Gamazyme BTC.
Key Benefits
Biological Cleaning Action
Specialized bacterial strains help digest biodegradable organic deposits rather than simply masking or chemically dissolving them.
Helps Control Odours
By degrading organic materials responsible for unpleasant sanitary-system odours, the product can support better odour control.
Low-Foaming
The formulation is designed with low-foaming cleaning characteristics, which is particularly relevant to marine sanitary and vacuum-flushing systems.
Biodegradable Formulation
The reference formulation is described as biodegradable and suitable for marine sanitary and sewage-treatment applications.
Helps Protect Biological Sewage Treatment
Aggressive cleaners containing acids, caustics, bleaches or disinfectants can adversely affect the microorganisms responsible for biological sewage treatment. RXSOL BTC ZYME is intended as a biological alternative for routine sanitary cleaning.
