It is tempting to wipe a dusty lens immediately. Instead, follow the manufacturer’s conservative approach: a dry, soft cloth for the body and LCD, and a commercially available blower for dust on the lens. This is general Canon guidance, not an instruction to disassemble a camera; your model manual takes priority.
