Thanks to the community, especial thanks to @JCERRN. I was able to use a sponge and soap water to wipe it off. It saves me a trip to the SC. Tesla's service appointment via the application is a joke. They never respond to my inquiry about the mark. It's almost impossible to get a hold. I guess...
I saw many inventory Cybertrucks in Upland Service Center had many CTs with similar marking around late November 2024, including mines. I didn't notice it until later in the days. Did anyone else experience a similar situation? Do you just schedule a service appointment to have them taken care...
