Why are there noticeable glue marks on the water tank housing of the Mijia Smart Evaporative Humidifier Pro?

The yellow sticker on the Mijia Smart Evaporative Humidifier Pro uses removable adhesive. Due to the high temperatures during recent transportation, some adhesive can remain after removal. Please use alcohol wipes to remove any glue marks, and this will not affect normal use. Do not use solvents such as makeup removers.
Here is more information about the glue marks of the device:
1. These glue marks are purely cosmetic and do not indicate a defect or quality issue.
2. They occur because the adhesive is applied to keep the sticker in place during shipping and handling.
3. Avoid scraping or using harsh chemicals, as this can damage the water tank surface.
