I'm trying a couple gallons of MEK. I'll let you know.

JMHO, MEK evaporates too fast and is very harmful to you. Zep makes a heavy duty cleaner called 505, it will amaze you how fast it cuts through motor grease, crime, exc.. I've had great success with Zep 505, I use it all the time and a gallon of 505 is less than 10 bucks (cheaper than MEK). Pour it in slosh it around for a few minutes and rinse it out with hot water, repeat as necessary.

BTW, $350 to boil a tank is more than 300 too much, time to find another radiator shop..
