A hydration reservoir is one of the most convenient tools for staying energised on adventures, but only if it's clean. Over time, water can leave a chalky build-up, sugary drink mixes can create sticky residue, and warm storage can invite mould and bacteria. A proper clean keeps your hydration system tasting fresh and working at its best.
Here's your complete, Gregory-approved cleaning method.
1. Gather Your Cleaning Gear
You'll need:
- Warm (not boiling) water
- Mild dish soap
- Gregory reservoir cleaning kit (includes large reservoir brush + small hose brush)
- A clean, ventilated drying space
Products Used
- Reservoir Cleaning Kit
- 3D Hydro Reservoir 3
2. Cleaning the Reservoir
- Fill the reservoir about one-third full with warm water.
- Add a drop of mild dish soap.
- Seal the lid and shake vigorously for 20-30 seconds to loosen dirt.
- Use the large brush from your cleaning kit to scrub all corners, including the bottom seam, top edges, and inside the lid.
- Rinse 5-6 times with fresh water to ensure all soap is gone.
- Hang the reservoir with the lid open until completely dry. You can use the integrated QuickDry hanger for this.
3. Cleaning the Hose
- Disconnect the hose using the quick disconnect button.
- Feed the small hose brush from the cleaning kit through, scrubbing back and forth to loosen buildup.
- Rinse thoroughly until the water runs clear.
- Let the hose dry for 24 hours before reconnecting.
4. Common Mistakes to Avoid
- Using boiling water: This could damage the reservoir material. Stick to warm water.
- Sealing before dry: Trapped moisture can grow mould.
- Harsh chemicals: Avoid bleach or abrasives, they can weaken materials.
5. How Often Should You Clean It?
- After every trip if you've used electrolyte or flavoured mixes.
- Once every 2-4 weeks for plain water use, depending on frequency.
- Immediately if you notice discolouration, odour, or residue.
Keeping your Gregory hydration pack clean isn't just about taste, it's about ensuring your gear stays ready for the miles ahead. A little attention after each trip means your next sip will always be as fresh as the first.
FAQ
Q: How do you clean a hydration pack quickly after a trip?
A: Rinse with warm water, shake, and hang to dry. A deep clean isn't always needed after plain water use.
Q: Can I store it in the freezer?
A: It is possible, but we don't recommend it. Proper drying and storing in a cool, ventilated space is a better way to keep it fresh between uses.
