Can I substitute nondenatured ethanol for denatured alcohol when soldering with boric acid?

Yes, it is acceptable to substitute nondenatured ethanol for denatured alcohol when mixing with boric acid to prevent the oxidative coating known as "firescale".

When substituting non-denatured ethanol (like Culinary Solvent or Everclear 190 proof) for denatured alcohol, use a substitution ratio of 1:1. 

For example, if your original recipe calls for 8 fl oz of "denatured alcohol", substitute 8 fl oz of Culinary Solvent 200 proof ethanol.
