Water Bottle Descaler
A vinegar and rice scrub that removes mineral film and odor from reusable water bottles
30 min beginner Yields 1 treatment
Ingredients
- 1/2 cup White vinegar
- 1 cup Warm water
- 2 tbsp Uncooked rice (acts as a gentle abrasive)
- 1 tbsp Baking soda
- 1 Bottle brush
Steps
- Rinse the bottle with warm water and pour out any remaining liquid.
- Add 1 tablespoon baking soda and 1/2 cup vinegar. Let fizz 30 seconds.
- Add 2 tablespoons uncooked rice and 1 cup warm water.
- Cap securely and shake vigorously for 30-45 seconds.
- Let sit 15-20 minutes.
- Shake again for 15 seconds.
- Pour out and scrub remaining residue with a bottle brush, especially the bottom and cap threads.
- Rinse at least 3 times. Air dry upside down with cap off.
Why It Works
Vinegar dissolves mineral scale. Baking soda neutralizes odor from organic compounds. Rice grains act as a physical abrasive that reaches curved bottoms and narrow necks a brush cannot.
Tips
- Soak the cap separately in vinegar water for 15 minutes. Scrub the seal groove with a toothbrush.
- Do not use on insulated bottles with dents or cracks — liquid trapped in the void causes mold.
- For extreme odor from milk or smoothies, fill with baking soda and warm water overnight before the vinegar treatment.
