To solve the bubbles, you can do the following general treatments:
1. Use the tip of the cotton swab needle to press against the bubble and try to squeeze out the air in the bubble.
2. Pull and adjust the film to open the gap in the bubble.
3. Use a hair dryer to blow on the bubble to speed up the gas squeeze out.
4. After patting the laundry detergent in the film with a paper towel, place the film on the bubble and press it with a hot towel to speed up the evaporation of the water content of the laundry detergent and make the bubble disappear.
5. After completely eliminating the bubbles, take a wet cloth and wipe the surface of the film clean to decorate the surface of the film.
