Ensure all parts are dry before assembly to prevent moisture buildup.
3. Operating Instructions

4. Maintenance
- Dishwasher Safe: The YETI Rambler 20 oz Travel Mug and its Stronghold Lid are dishwasher safe. Place them on the top rack for best results.
- Hand Washing: For thorough cleaning, especially for the lid, hand wash with warm, soapy water.
- Lid Disassembly for Cleaning: The magnetic slider on the Stronghold Lid can be easily removed for deep cleaning. Simply push the slider forward until it detaches from the lid. Wash all components separately. Reattach the slider by aligning it and pushing it back into place until it clicks.

Regular cleaning prevents residue buildup and ensures optimal performance.
5. Troubleshooting
- Beverage Not Staying Hot/Cold: Ensure the Stronghold Lid is twisted on tightly and the magnetic slider is fully closed. Check for any debris or damage to the lid's gasket that might compromise the seal.
- Lid Leaking: Verify that the lid is correctly aligned and securely twisted onto the mug. Confirm the magnetic slider is in the fully closed position. Inspect the lid's gasket and slider mechanism for any wear or damage.
- Difficulty Opening/Closing Slider: Clean the magnetic slider and its track thoroughly to remove any sticky residue. Ensure the slider is properly reassembled after cleaning.
