Smart ways to clean a greasy metal vessel? I cooked up some meatloaf in a copper dish and it came out great. The dish itself, a little less so. I don't want to scratch the surface or wash it down the drain, what are some good ways to clean this without pulling out my hair?
The secret to getting meat loaf off is to first soak it in cold water for a good 15 minutes or longer. Cold water soaks are good for high protein food like eggs and meat as well as starches like oatmeal. On a scratch-able surface I like to use a butter knife to gently pry off the material that doesn't wipe off after a soak. Fingernails work too if yours are long enough. Then a gentle rub with a plastic scouring pad, not metal. You just have to keep at it. 

This is why I use non-stick, ceramic or glass for meat loaf! It isn't glue, but it's close.
