(b) Immerse 5–40 s in 5 % HNO3 solution.
To remove stain, immerse 25 s in 10 % HCl-methanol solution.
(c) For Inconels and Nimonics, use 5 mL HNO3 solution—electrolytic at 5–10 V for 5–20 s.
(d) Swab or immerse several minutes.
(e) Swab 5–60 s.
HNO3 may be increased to 30 mL in methanol only depending on alloy.
