Keep your boat’s toilet and black water system clean and flowing properly with TRAC Sew Clean, a professional marine sanitation system cleaner specifically formulated to dissolve uric scale and stubborn deposits inside toilets, hoses, pipes and holding tanks.
Unlike conventional sewage treatments that primarily manage waste or odors, Sew Clean is designed to clean the actual black water system. It attacks deposits deep inside the plumbing, helping remove the buildup responsible for blockages, reduced flow, overflows and unpleasant odors.
For yacht and boat owners, this means a thorough internal clean from toilet to holding tank without dismantling the plumbing.
Dissolves Uric Scale Inside the System
Uric scale is a common problem in marine toilet systems. Over time, deposits can accumulate inside hoses and pipes, gradually reducing their internal diameter and restricting flow.
Eventually, this buildup can contribute to:
- Blocked toilet pipes
- Reduced waste flow
- Plumbing overflows
- Persistent unpleasant odors
- Restricted hoses and fittings
- Increased maintenance requirements
TRAC Sew Clean is specifically formulated to attack this uric-scale buildup and dissolve deposits inside the black water system.
It is particularly useful when strong odors, blockages or flow problems indicate that scale may have accumulated inside the system.
Cleans from Toilet to Holding Tank
The biggest challenge with marine sanitation systems is that much of the plumbing is hidden and difficult to access.
Sew Clean solves this problem chemically rather than mechanically.
The product is introduced through the toilet and flushed into the system, allowing it to reach internal hoses, pipes and other areas that would otherwise require dismantling.
This makes it possible to clean from the marine head to the black water tank while minimizing messy and time-consuming disassembly.
No Need to Dismantle the Plumbing
Removing sanitation hoses and pipes is rarely an enjoyable maintenance job.
TRAC developed Sew Clean specifically to provide effective cleaning without removing the piping or creating unnecessary mess.
This offers several practical advantages:
- Less dismantling
- Reduced maintenance time
- Access to difficult internal areas
- Less direct handling of contaminated plumbing
- Thorough cleaning of the complete flow path
For preventive yacht maintenance, this can make regular black-water-system cleaning considerably easier.
Not a Sewage Treatment Product
An important distinction is that Sew Clean is a cleaner, not a sewage treatment chemical.
It should not be considered a replacement for the normal treatment products used in a black water holding tank.
Its job is different: Sew Clean removes the uric scale and accumulated deposits inside the system itself.
TRAC also states that Sew Clean should not be mixed or used simultaneously with other sewage additives. The black water tank should be pumped out and normal sewage treatments replaced after the Sew Clean cleaning procedure has been completed.
How Much Sew Clean Do You Need?
For cleaning marine toilet systems, TRAC provides a simple guideline:
Use 1 Quart of Sew Clean per toilet/head.
Start with the highest head in the system and continue toward the lowest, adding one quart per toilet and flushing each head once.
This means the 1 Gallon (3.78L) container provides four 1-Quart doses, although the actual quantity required for a particular boat depends on the number and configuration of its toilet systems.
Always follow TRAC’s current application instructions for your installation.
6–12 Hour Treatment Time
After Sew Clean has been introduced into the system, TRAC recommends allowing the mixed solution to remain in the plumbing for:
6–12 hours
The manufacturer specifies that the treatment should not exceed 24 hours.
This contact time gives the solution an opportunity to attack and loosen uric-scale deposits inside the plumbing.
After treatment, each toilet/head should be flushed at least 10 times to remove loosened residue from the system.
Cleaning the Black Water Holding Tank
Sew Clean can also be used to clean the black water holding tank itself.
For holding-tank cleaning, TRAC recommends a 4:1 dilution — four parts water to one part Sew Clean.
Where possible, the tank should first be flushed with water a couple of times to remove loose waste. This allows the Sew Clean solution to work more directly on deposits attached to the tank walls.
The amount required depends on the capacity of the holding tank, so the manufacturer’s instructions should be followed when calculating the required volume.
Suitable for VacuFlush Systems
TRAC also provides specific guidance for using Sew Clean with VacuFlush systems.
The VacuFlush system should first be switched off at the breaker. One quart of Sew Clean is then added per head and flushed into the system.
TRAC recommends allowing the solution to remain for 6–12 hours, followed by flushing with fresh water. The holding tank should then be pumped out shortly after the cleaning procedure is completed.
Always refer to the current TRAC instructions and the sanitation-system manufacturer’s requirements before use.
Designed for Common Black Water System Materials
According to TRAC, Sew Clean is formulated for compatibility with the materials commonly found in marine black water systems, including:
- Metals
- Plastics
- Gaskets
- Seals
- Common sanitation-system components
This allows the product to clean internal deposits without requiring aggressive mechanical cleaning of the plumbing.
100% Biodegradable
According to TRAC, Sew Clean is 100% biodegradable.
Disposal must still be carried out in accordance with applicable local environmental and waste-disposal regulations, particularly because regulations for black water and sanitation waste vary depending on geographical location.
Preventive Maintenance for Marine Toilets
You don’t have to wait until a toilet becomes completely blocked before cleaning the system.
TRAC recommends cleaning a marine black water system approximately every 6–12 months as a general preventive-maintenance guideline.
Regular cleaning is particularly important for toilet systems that use salt water for flushing, where uric scale and salt/calcium buildup can become a greater concern.
Signs that your system may need cleaning include:
- Strong odors from the marine heads
- Slow or restricted flow
- Frequent blockages
- Toilet plumbing backing up
- Suspected scale inside hoses
- Reduced internal diameter of sanitation pipes
Preventive cleaning can help tackle these deposits before they develop into more serious plumbing problems.

Clean the Black Water System Without Taking It Apart
Marine toilet problems are often caused by what you can’t see. Uric scale can gradually build up inside sanitation hoses and pipes until flow becomes restricted, odors become stronger or a blockage develops.
TRAC Sew Clean is designed specifically to reach those hidden deposits.
Instead of dismantling the sanitation plumbing, Sew Clean passes through the existing system and works directly on uric-scale buildup from the toilet toward the holding tank.
This makes it an excellent choice both for addressing existing scale-related problems and for preventive maintenance of marine toilet and black water systems.
Choose TRAC Sew Clean Toilet System Descaler 1 Gallon from Cavo Yachting to keep your boat’s sanitation system cleaner, reduce problematic buildup and maintain better flow from head to holding tank.
