How To Refresh Your Reusable Water Bottle With Vinegar
TikToker @carolina.mccauley has shared a simple and effective solution to a common problem many reusable water bottle users face: unpleasant odors emanating from their bottles.
To address this, simply pour a cup of vinegar into your water bottle, then top it off with water. You have the option to give it a shake, but it isn't always necessary.
Meanwhile, soak the bottle's lid in a bowl filled with the vinegar-water mixture. Let the bottle and lid sit for 10 minutes, then rinse them thoroughly and set them aside to dry.
You can use a clean towel to dry any reachable areas of the bottle. If the smell persists, you may need to treat your bottle with a tougher solution or purchase a new one.
