How do you deep clean a Hydro Flask?

Answered by James Kissner

To deep clean a Hydro Flask, distilled white vinegar is the perfect solution. It’s a natural cleaner that effectively removes stains and discoloration. Here’s a step-by-step guide on how to deep clean your Hydro Flask using vinegar:

1. Gather your supplies: You’ll need distilled white vinegar, warm water, a bottle brush or sponge, and a soft cloth or paper towel.

2. Empty the bottle: Pour out any remaining liquid from your Hydro Flask and remove the cap and any accessories.

3. Prepare the vinegar solution: Fill the bottle about halfway with distilled white vinegar. Depending on the size of your bottle, you may need more or less vinegar.

4. Swish the vinegar around: Close the cap tightly and gently shake the bottle to ensure the vinegar covers the entire interior. Swish the vinegar around, making sure it reaches all corners and crevices.

5. Let it sit: Leave the vinegar solution inside the bottle for about five minutes. This allows the vinegar to penetrate and break down any stains or discoloration.

6. Scrub the bottle: Use a bottle brush or sponge to scrub the interior of the bottle. Pay extra attention to areas with stubborn stains or residue. The bristles of the brush or the sponge will help loosen and remove any grime.

7. Rinse thoroughly: Empty the vinegar solution from the bottle and rinse it with warm water. Make sure to rinse thoroughly to remove any remaining vinegar residue.

8. Repeat if necessary: If there are still visible stains or discoloration, repeat the process of filling the bottle with vinegar, swishing it around, and letting it sit for five minutes. Scrub again and rinse thoroughly.

9. Dry and inspect: After rinsing, use a soft cloth or paper towel to dry the bottle. Inspect it carefully to ensure all stains and discoloration have been removed. If needed, repeat the cleaning process until the bottle is completely clean.

Remember, regular cleaning and maintenance can help prevent the buildup of stains and discoloration in your Hydro Flask. It’s a good practice to clean it after each use, especially if you’ve used it for beverages like coffee or tea that can leave stubborn stains.
