How to Clean Hydro Flask

What You'll Need

• Soap-Man Lemon Glow Dish Soap
• Bottle brush
• Baking soda
• White vinegar
• Hot water

Step-by-Step Instructions

1. 1

   Disassemble

   Remove the lid and any silicone parts. Hydro Flask lids have multiple parts that need separate cleaning.

2. 2

   Wash with hot soapy water

   Fill the flask with hot water and dish soap. Scrub thoroughly with a bottle brush, reaching all the way to the bottom.

3. 3

   Clean the lid

   Wash all lid parts with soapy water. Use a small brush to clean inside the gasket groove and any threaded areas.

4. 4

   Deep clean if smelly

   Fill with hot water, 2 tablespoons baking soda, and 1 cup white vinegar. Let fizz for 30 minutes, then rinse.

5. 5

   Air dry upside down

   Air dry upside down on a drying rack with the lid off so all moisture evaporates.

Pro Tips

• TIPUse a long-handled bottle brush to reach the bottom of tall Hydro Flasks.
• TIPClean the lid weekly -- this is where mold typically grows undetected.

Common Mistakes to Avoid

• XPutting Hydro Flasks in the dishwasher, which damages the vacuum insulation and voids the warranty.
