A good, soft, and most importantly CLEAN cotton or microfiber cloth with some isopropyl is what I use. Rinse any dirt or debris in the sink, then iso on the cloth and clean/dry. It’s not the cloth that scratches lenses, it’s the dirt and harder bits of dust that rub on the lens using the cloth.

Yeah. Soap and water then a lens cloth with the lens cleaning solution. Those single use towelette things are so rough and dry - they just smear finger prints.
