The use of plastic cups is very convenient, but at the same time, it is also necessary to pay attention to some usage methods and precautions to ensure safety and environmental protection.

Instructions for using plastic cups:

1. First time use: Newly purchased plastic cups usually have some chemical odors. To remove these odors, you can first clean them several times with warm water and a small amount of neutral detergent.

2. Cleaning: Ensure that the inside and outside of the plastic cup are clean before use. It can be hand washed with warm water and detergent, or placed in the dishwasher for cleaning. It is not recommended to use a brush to scrub to avoid damaging the cup wall.

3. Disinfection: If plastic cups are used to hold food or beverages, especially for infants or children, they can be regularly disinfected with hot water and disinfectants.

4. Applicable temperature: Determine the applicable temperature range of the plastic cup based on its material. For example, PC cups may release harmful substances at high temperatures, while PP cups can be safely heated to 120 degrees Celsius.

5. Avoid microwave heating: It is not recommended to put plastic cups in the microwave unless it is clearly indicated on the cup that microwave heating is possible.

6. Avoid direct sunlight exposure: Prolonged direct exposure to sunlight may cause plastic cups to deform or fade.

7. Storage: After use, the plastic cup should be stored upside down to keep it dry and prevent bacterial growth.
