Cleaning Hacks: How To Keep Your Bottle Clean
Adventures are better with a clean Hydro Flask! Whether you're summiting mountains or conquering Monday meetings, these three simple cleaning methods will keep your favorite hydration companion performing at its best. From quick rinses to deep cleaning solutions, we've got you covered for bottles, tumblers, and more—so you can focus on staying hydrated and enjoying what matters most.

Method 1: Dishwasher-Friendly Convenience
Let your dishwasher do the work! Most Hydro Flask bottles and tumblers are dishwasher safe—just look for products without the trademark symbol next to the logo (Trail Series bottles excluded). For best results:
- Separate all components: place straws, caps and lids on the top rack
- Skip cleansers containing bleach or chlorine to preserve your bottle's integrity
- Run a normal cycle and enjoy that fresh-out-of-the-box clean feeling
Method 2: The Classic Hand Wash
Sometimes the personal touch makes all the difference. Hand washing is perfect for products like our mugs (which aren't dishwasher safe) and lets you reach those hard-to-clean spots. Our recommended approach:
- Use warm, soapy water and a bottle brush for a thorough clean
- Try our purpose-built Clean and Bright Bundle for professional-grade results
- Air dry completely using our specially designed Bottle Drying Rack with dedicated space for straws and accessories
Method 3: The Deep Clean Refresh
Coffee stains? Lingering smoothie residue? Sometimes your favorite bottle deserves extra attention. Our simple DIY solution works wonders on stubborn stains:
- Mix ½ cup hydrogen peroxide with 2 tablespoons baking soda
- For tough residue, let the mixture sit for 30 minutes
- Finish with soap and warm water for a like-new shine
Why Regular Cleaning Matters
Keeping your Hydro Flask clean doesn't just enhance your drinking experience—it extends the life of your bottle and ensures maximum performance. Whether you're an everyday cleaner or an occasional deep-cleaner, these methods help maintain your bottle's temperature retention properties and fresh taste with every sip.
