Query: Temperature markings wash off

As with many other reviewers here, mine had baked-on grease and when I washed it the numbers washed off. A thermometer is not very useful if you can't read it.I bought it because of the Cooks Illustrated recommendation -- I guess that they never had to wash it off when they tested it. A big oversight on their part. I would choose a different thermometer.
