There’s a lovely item in today’s Korea JoongAng Daily about a report by the Bank of Korea (including the above image) on how people have been attempting to disinfect their banknotes to protect themselves from Covid-19. Putting them in the washing machine and then the tumble dryer, or microwaving them, is not recommended. “The central bank said in the first half of this year, 2.7 trillion won worth of bills were damaged due to soaking or burning.”
