I like Dawn and Shout as well.
Shout saved my DDs life once. When she was 3 she got ahold of a black sharpie and while I was doing laundry she was drawing great big black x's on every stair (2 story house, newish carpet). Shout and a damp rag got it out!
My father was a mechanic, i can remember my mother sometimes using crisco shortening to get that heavy, nasty axle type grease out. Apply a little, scratch with a fingernail and it would lift.
