I rinsed it out and sprinkled baking soda on the sides and on the bottom.
I just happened by lucky coincidence to have an empty spray bottle rolling around in the kitchen, so in went the vinegar. (Like my stack of clean dishes back there?)
I sprayed the vinegar all over the pan. I probably got a little carried away because, of course, it makes bubbles and its FUN! I let it set for a while, spraying it again whenever I happened to be in the kitchen (cause it will keep bubbling).
One Harry Potter movie later: I used hot water (the hotter the better cause its greasy) and a scrubby pad to scrub off all the ick. The sides are the hardest part though since they don't get to sit in the paste the duo makes, but with a bit of elbow grease on my part, this was my result:
Please, no applause.
Obviously there are still some sticky looking spots on the sides and over on the right, but WOW major improvement! I will probably hit it with another spot specific treatment tomorrow. I bet this will work on my icky baked on gunk cookie sheet too... hmmmm.
