Use liquid paint stripper. Its cheap and you don't have to do much work. There are sections where it won't take the paint off (for reasons I don't know) so use some sand paper and take the paint off in those sections.
Actually, chemical stripper
IS the best way to REMOVE POWDERCOATING!
Grinding or blasting will risk damaging the frame if used to remove powdercoat.
Read the paint stripper can carefully, especially the part about brushing it on going in one direction only.
The spots that don't come off on the first try, need to be done a second or even 3rd time.
I wear long rubber gloves and wipe the yucky paint & remover off with lots of paper towels.
Then I rinse, dry and reapply the stripper.
3 doses of stripper should get about 98% of the old paint off. The last little bits can be picked off or shaved off with an old pocket knife.
Then give the frame a thorough final rinse & dry.
Clean with wax & grease remover.
Then use a super gritty ScotchBrite pad to give the steel that "brushed" look.
Reclean with wax & grease remover.
Then give the frame a rubdown with some good car wax. Do that every once in a while and you should be good to go.
At least for a sunny Sunday ride!
Or instead of using car wax as the final step, have the brushed bare steel frame clear powderoated.
Better yet, candy color powdercoat over the brushed steel.
