For friends, the brand LOGO on the film can be wiped gently with a clean cloth dipped in some alcohol. If it cannot be wiped off, you will need to use a carburetor cleaner, but some cars The film can only erase the words on the surface of the film. There is another layer that cannot be erased if it reaches the inner layer (but it is very shallow and does not affect the line of sight). Note: After wiping the words, wipe the original place with water with clean water. I am Li Hua from Shenzhen, and I have been engaged in the film industry for 14 years. Hope the answer can help you. Happy driving!
