Overview
- For drains in bathrooms and kitchens, experts advise pouring about a cup of white vinegar, letting it sit 15–30 minutes (some guides suggest 5 minutes), scrubbing, and flushing with hot water.
- Recommended frequencies are once a week for high‑use kitchens and baths, every 15 days for low‑use laundry areas, and up to twice weekly in very humid spots.
- Shower curtains should be sprayed fully with white vinegar, left to act 15–30 minutes, lightly scrubbed if stained, and rinsed, with upkeep suggested weekly or every 10 days.
- A broom‑care soak commonly cited is 1 liter hot water, 1 cup white vinegar, and 2 tablespoons coarse salt, followed by a rinse and sun‑dry; clean monthly, or every 15 days with pets or heavy traffic.
- Coverage cites studies in the Journal of Food Protection and the International Journal of Environmental Health Research showing acetic acid reduces bacteria such as E. coli and Salmonella, and it stresses not to mix vinegar with bleach due to toxic fumes.
