What the... why didn't you just sell/reupholster your cars if you were so sure they were a problem??? Or bleach the hell out of your clothes and stuff @ your washing machine's max heat setting a couple of times?!?!
...and why on earth did you need a new driver's license? HINT: clean laminated/plastic cards cannot grow mold. EVER. Tiny bits could theoretically get on them, but nothing a wipe with a cotton ball soaked in rubbing alcohol wouldn't get out.
