Can I Use a Black Tank Cleaner in my Grey Holding Tank Too?
Can You Use a Black Tank Cleaner in an RV Grey Tank?
Quick Answer: Some RV owners use black tank cleaners in their grey tanks to help clean sensors, but these products are not specifically formulated for grey water buildup. For grease, food particles, and organic sludge in grey tanks, a dedicated grey tank treatment is recommended.
Is It Safe to Use Black Tank Cleaner in a Grey Tank?
Black tank cleaners are formulated primarily to break down waste and toilet paper. While they were not specifically designed for grey water systems, some RV owners report success using them to address sensor buildup inside grey tanks.
If used for this purpose, allow the solution to remain in the tank for at least 12–24 hours, or longer if needed, to help break down residue.
How Do You Apply a Black Tank Cleaner to a Grey Tank?
- Dissolve one packet in a plastic cup using room-temperature tap water.
- Stir gently until fully dissolved.
- Pour the solution down a sink drain connected to the grey tank.
- Fill the grey tank to near full capacity for best coverage.
- Allow 12–24 hours of soak time before dumping.
A fuller tank allows the treatment to contact sensors and tank walls more effectively.
What Causes Grey Tank Odors and Buildup?
- Grease from dishwashing
- Food particles
- Soap residue
- Organic sludge
- Buildup on tank walls and sensors
Unlike black tanks, grey tanks accumulate fats, oils, and soaps that require targeted formulas for optimal breakdown.
What Is the Best Treatment for RV Grey Tanks?
For regular grey tank sanitation and odor control, use a product specifically formulated for grey water systems. Elemonate is designed to break down grease, food particles, and organic sludge while freshening the tank.
Using a treatment formulated for grey tanks ensures more effective buildup removal and odor management.
When Should You Deep Clean a Grey Tank?
- Sensors are reading inaccurately
- Persistent odors are present
- Drainage seems slow
- Tank hasn’t been cleaned in months
