Maintenance
Cleaning:
The scale features a waterproof and dustproof design. To clean, gently wipe the surface with a soft, damp cloth. Avoid using abrasive cleaners or submerging the scale in water. Ensure the scale is dry before storage or next use.

The silicone heat pad helps protect the scale surface from high temperatures and heat, while also providing a non-slip surface. It is designed to be waterproof and prevent water stains. Clean the silicone pad separately if needed, and ensure it is properly placed back on the scale.
Storage:
Store the scale in a cool, dry place away from direct sunlight and extreme temperatures. Do not place heavy objects on the scale when not in use.
