Ensure the lid is fully closed and sealed. Pre-heat or pre-chill the mug with hot or cold water for a few minutes before filling with your beverage to maximize insulation performance. Check if the double-wall vacuum seal is intact; if compromised, the insulation will be affected.

Ensure no dried residue is present around the lid seal or opening mechanism. Try washing the lid thoroughly. If it persists, check for any obstruction or damage to the fliptop mechanism.

Confirm that the fliptop lid is completely closed and locked. Ensure the silicone seal on the lid is clean and properly seated. Check the mug for any dents or damage that might affect the lid's seal.

Disassemble the lid as per the user manual. Use a small brush or pipe cleaner to reach tight spots. Both the mug and lid components are dishwasher safe (top rack recommended).
