3. Ingredients
For a complete list of ingredients, please refer to the product packaging.
4. Setup & Operating Instructions
- Preparation: Apply the product when the drain will not be used for a minimum of 6 hours. This allows the enzymes and bacteria sufficient time to work effectively.
- Mixing: Mix one scoop (approximately one tablespoon) of the granular concentrate into 12 ounces of warm water. Stir until dissolved.
- Application: Carefully pour the mixed solution directly into the affected drain.
- Activation Time: Allow the product to remain in the drain for at least 6 hours. For best results, an overnight application is recommended.
- Flushing: After the activation period (minimum 6 hours), run warm water down the drain for 30 seconds to flush the line.
For optimal results and to address stubborn clogs, repeat this application process for four consecutive days. The product includes a convenient scoop for accurate measurement.
5. Maintenance
To prevent future clogs and maintain clear drains, repeat the application process monthly or as needed. Regular use helps to continuously break down organic buildup before it can cause significant blockages.
6. Troubleshooting
- Slow Drains Persist: If drains remain slow after the initial application, ensure the product was left undisturbed for the recommended 6-8 hours. Repeat the 4-day application cycle.
- Severe Clogs: For completely blocked drains, mechanical removal of the primary obstruction (e.g., using a snake) may be necessary before applying the K-67 cleaner for residual buildup.
- Insufficient Water: Ensure 12 ounces of warm water are used for mixing to properly activate the granular concentrate.
