Anyone know how to remove the black coating (paint? tar? something else?) on "black iron pipe" that is sold at Lowes/Home Depot?

I'd rather not grind/sand it off. Some type of solvent would be preferable so as to not affect the steel underneath.

Pickling is the proper way to do it.

Just bring it somewhere to get it sandblasted. Much easier than chemical strippers.

Buy a gallon of MEK. methyl-ethyl-ketone. I sell cutback coatings to the pipe fitting industry. Different types of solvents will soften up and clean the pipe but the fastest way is just soak it n the MEK which you can buy locally at a paint store.

Why wouldn't you just go and buy some schedule 40 pipe un coated bro??? Any steel yard will have both that and structural pipe uncoated, cheaper too.

Just go buy some rigid or galvanized pipe. Why the hell would you through that much trouble?

Acetone or denatured alcohol should do the trick.

Good luck, you're making a mistake. Why not buy a short piece and do your damnedest to make it look like you want, then go buy galvanized.
