Well, it wasn't something I *TOUCHED* on a regular basis, but in college I worked for a wings shop that was moving RIGHT after I got hired. So I was on the detail that got to clean the fryers in mid-move.

Holy. Cow.

Luckily, they had the foresight to rent some pressure washers and put them in the back parking lot (we were just moving them down the street). The backside of a commercial deep-fat fryer that's been in-place for 20 years or so? Wow. Words can't EVEN describe.
