Dilema what to do

[Myka]

The biggest differences between using acid and using lanthanum chloride is time and precaution. Acid is quicker and possibly risky to your health if you're not smart about it or you have an accident, but in my experience doesn't remove all phosphate (just what's bound to the surface). Lanthanum chloride is safer and in my experience more complete, but takes longer.

The point of soaking after the bleach is not to get rid of the bleach, it's to leach the phosphate and nitrate out.
