On bare metal I use TSP. USE as directed then use wax and grease remover and tack cloth before painting.

Purple Power works good.

Fuel oil then your grease and wax remover.

Lacquer thinner or acetone.

I used Gunk engine degreaser to get all of the tar residue off, and then sprayed
Purple Power degreaser to get everything squeaky clean and then pressure washed it.
a little scotch-Brite and you're ready for paint.
