While hydrochloric acid (HCl) has historically been the standard, milder acids are being used to provide gentler dye removal. Part of this trend is due to the use of automated staining, which must accommodate the movement of the robotic arm in addition to the time spent in the reagent. Premium fencing blades are often offered with a blued finish. This finish allows them to be stored in high-moisture conditions, like sports bags, without rusting.
