Is there a chemical method to removing mill scale? I'm working with 14ga and removing mill scale is just time consuming and generally not a fun job. I hit it with a stone disc to get the majority of it off & then flapdisc to desired finish. Among other problems is that heat generated from the stone & flapdiscing will sometimes warp the piece.
Anyone know of a chemical method? How about muriatic acid? Do they make a "stripper" chemical for steel?
Alternatively, I hope to buy a blasting gun & cabinet soon, what kind of media should I use to remove mill scale? Would walnut shells do the trick or will I need something harsher?
Thanks to those who responded to my clearcoating question.
