Suggested Time: Bedtime • Weekly • 5 mins
Flush kitchen sink drains with hot water and dish soap every Sunday night to prevent odor and clogs.
Precautions & Patch Test Guidance
If your kitchen drainage pipes are made of lightweight thin PVC or flexible plastic hoses, use very hot tap water (60-65°C) instead of rolling boiling water to avoid warping joints.
For any topical preparation, always conduct a 24-hour inner-arm skin patch test first. Informational traditional wisdom only—not medical advice. Read full Health Disclaimer .
