Mentioned by numerous pilots as THE must have product $6.99
Every day we all worry about spilling coffee or splashing pasta sauce on our white shirts. Best way to handle this is with the Tide Pen. Apply some liquid on the spot in as soon as you get to the hotel or immediately add water to clean the spot. Not sure anything works as well. This has been mentioned at least three times by pilots that I have spoken with about stains. You can buy individually but a pack of 3 may be the best bet.
