Any suggested cleaners to use or not use on the touchscreen? Paper towels or microfiber cloths or whatever? The manual says: 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. But I can't help but think that some sort of liquid cleaner will do better. I've been using Windex on laptop screens for years and never had a problem.
