Been there. I used an angle grinder (bad idea).

Putty knife and elbow grease. Clean up any surface rust with naval jelly, wash, repeat. Eastwood has this stuff that is a rust encapsulator for $20/can, supposed to work really well (for that price it better). I'll be getting some myself so I can hopefully make short work out of cleaning up the frame.

I have seen people use dry ice and a chisel and it comes off in pieces.
