What to do if the inner coating of the Thermos is scratched?
Scratches on the inner coating of the thermos are a common problem that not only affects the appearance of the cup, but may also affect its insulation performance. Here are some solutions for scratches on the inner coating of the thermos:

1. Clean and assess the damage
First, use a soft cloth and a mild detergent to clean the scratched area, making sure to clean it thoroughly to remove any remaining dirt or impurities. This step is necessary because it can help you more accurately assess the severity of the scratch.

2. Use repair paste
For shallow scratches, you can use a special stainless steel repair paste to repair it. Apply the repair paste to the scratched area and gently wipe it with a soft cloth until the repair paste is fully penetrated and evenly distributed

3. Spray paint repair
If the scratch area is large, you can choose to buy oil spray paint of the same color in the store or online to re-spray it. You can choose the one with the least dosage. If the scratch area is small, you can also try to cover the scratch with nail polish of the same color.

4. Stickers or stickers
Spray paint may contain harmful substances. Therefore, to repair the paint peeling part of the thermos, you can use a good-looking car sticker, choose the desired style, and then stick it on the paint peeling part. In addition, many thermos brands will come with stickers, which are usually thin and will not affect the feel.

5. Scrape or clean the paint thoroughly
If you don’t have high requirements for the appearance of the thermos, you can choose to completely scrape or clean the paint to reveal the original color of stainless steel. The feel of use after this treatment is still quite good. But please note that if the cup rusts after removing the paint, it is recommended to stop using it immediately, because this may mean that your cup is not made of real stainless steel, and continued use may affect health and safety.

6. Replace a new cup
When you encounter a serious paint peeling and you can’t stand it, the easiest solution is to replace a new thermos. Old cups can also be kept at home for storage purposes

7. Preventive measures
To prevent scratches on the inner wall, the following preventive measures can be taken: avoid collision or friction between the thermos and hard objects; avoid storing acidic or alkaline beverages in the thermos for a long time; regularly clean and maintain the thermos; choose high-quality stainless Steel Thermos to ensure that its surface is smooth and free of burrs
