Dawn is good stuff, but out of my price range by a few X's. In my neck of the woods, dollar store 'LA's Totally Awesome all purpose concentrated cleaner' has served me very well. Oh it's up to $1.25 now. I have taken decades of rancid grime off engines with that stuff. I took to reading the PDF data sheets on the cleaners to see what the active ingredients are. Most of it is marketing, but with a name like that it has to be good, no? It's like the 'Live Mega Doppler 7000 HD' radar on LA news channel 7 - it has to be the BEST!
