How can I safe my penpals' letters so they don't accidentally hand me the dreaded virus? The "official" line is that the virus can survive for perhaps three days on "surfaces". The "Perhaps" has me doubtful. I thought of wearing gloves to open the letters, discarding the envelopes (who knows where they have been?), and then ironing the letter sheets with the iron on the "linen" setting. Has anybody tried heat to see if any inks survive?
