โ Hydration Myths Busted: Your Top Questions Answered
Does stainless steel really keep water colder than plastic?
2025 thermal studies confirm stainless steel’s superiority. The CamelBak Eddy Stainless maintains ice for 34 hours vs plastic’s 9 hours in controlled conditions.
Is the bite valve hygienic?
The 2025 Eddy model features an antimicrobial valve tested to reduce bacterial growth by 76% compared to standard designs. Weekly cleaning is still recommended.
Can I put carbonated drinks in it?
Yes, but with caution. The stainless construction handles pressure well, but the valve system works best with still liquids. For sparkling water, open slowly.
How does it compare to glass bottles?
While glass avoids metallic taste completely, our 2025 drop tests show stainless surviving 15ft falls vs glass breaking at 2ft. Stainless also insulates better.
๐ง Maximizing Your CamelBak Eddy Stainless: Care & Usage Guide
Step 1: Initial Cleaning
Before first use, disassemble completely (bottle, cap, valve) and wash with warm soapy water. Use a bottle brush for the interior.
Step 2: Daily Maintenance
Rinse after each use. Every 3 days, soak the valve in vinegar solution (1:3 vinegar:water) for 15 minutes to prevent mineral buildup.
Step 3: Deep Cleaning
Weekly, use baking soda paste on stubborn stains. For odors, soak with lemon juice and coarse salt overnight.
Step 4: Storage
Store with cap open to air dry completely. Avoid leaving liquids in bottle for more than 48 hours to prevent bacterial growth.
