Hi! I am finished with the welding of my stand. However the weld points are now rapidly rusting (hot rolled steel tube). I need to somehow remove the mill scale so that I can paint my stand with rustoleum.
Anyone know how?

Sadly I can't remove the scale that sits on the inside of my stand's steel tubing and corrosion is rapidly setting in. I ended up buying some rust remover chemical that, theoretically, should remove not just rust but most iron oxides, so it might handle the mill scale as well.
Failing that I'm pickling it in vinegar.
Another option would be to use something like the POR15 system to clean and coat it, that would seal it up pretty well from corrosion.

See I looked at POR15 Metal Prep and ended up getting Metal Rescue instead - Metal Prep leaves a layer of Zinc Phosphate, and Zinc isn't a good thing to subject to gas burner temperatures.
