- Enzymes: These biological catalysts break down waste and organic materials, making it easier to clean the tank and preventing clogs.
- Live Bacteria: These beneficial microorganisms digest waste and help to maintain a healthy balance in the tank, reducing odors and buildup over time.
- Surfactants: These compounds lower the surface tension of liquids, allowing for better penetration and cleaning action, which helps to remove stubborn residues.
- Citric Acid: This natural acid is effective in breaking down mineral deposits and providing a fresh scent, while also helping to neutralize odors.
