TNTech Portable Thermal Flask 便携式恒温杯

To ensure safety and extend the lifespan of your heating flask, please follow the cleaning guidelines below:
1. Clean the Interior Only
- After each use, fill the inner chamber with clean water and gently wash using a soft cloth or non-abrasive sponge.
- For stubborn odors, tea stains, or residue, use a small amount of mild, neutral detergent. Rinse thoroughly with clean water to remove all soap traces.

2. Keep the Exterior Completely Dry
- The outer casing and bottom area contain electronic components and charging ports. Do not immerse, rinse, or place the flask in a dishwasher.
- If the exterior accidentally comes into contact with water, wipe it dry immediately with a soft cloth. Ensure all parts are fully dry before using or charging the flask again.

3. Important Precautions Before Cleaning
- Always switch off the power and allow the flask to cool down completely before cleaning.
- Do not use steel wool, abrasive pads, corrosive cleaners, or strong chemicals, as these may scratch the inner lining or damage the surface coating.

In Summary:
Clean the inside as normal, but keep the outside strictly dry. Never soak, rinse, or wash the entire unit. If water gets on the exterior, dry it immediately.
