In the remote chance you haven’t RTFM, Tesla’s Model 3 Owner’s Manual p135 specifies the following:
“Touchscreen
Clean the touchscreen using a soft lint-free cloth specifically designed to clean monitors and displays. Do not use cleaners (such as a glass cleaner) and do not use a wet wipe or a dry statically-charged cloth (such as a recently washed microfiber). To wipe the touchscreen without activating buttons and changing settings, you can enable clean mode. Touch Controls > Display > Screen Clean Mode. The display darkens to make it easy to see dust and smudges.”
With a good quality microfiber glass cloth you could probably just use a small section of it, damp (with water, preferably distilled), and the rest to wipe dry.
