[TheForge] finish problem

[John Allen]

If it is small enough, use a wire wheel, but sandblasting is the best
way to remove scale. Also use a heavier acid like muradic also named
hydrochloric. It has a horrible smell, will burn an open wound, but I
use it when I solder galvanized and it burns ygr galvanize off almost
instantly and leaves a clean scale free steel finish. It dilutes in
water and use baking soda for clean up.
