Hello: I have a question regarding sodium bisulfate, I wonder whether
you can help out. Do you know whether it can be added into a steel
pin magnetic barreller to help remove firescale?
With the 18K alloy we use, we find a hard casting surface which must
be removed before fine sandpapering is effective - and I’m looking
for the best way to accomplish this.
There are solutions available for this purpose such as “super
sunsheen descaler” from Rio Grande, but they’re not for export (are
hazardous materials). I need to remove the firescale without removing
any gold. Pickling alone is insufficient. Thank you.
