Questions about the use of muriatic acid (HCL)

[Ian]

HCl is non reactive with placstic but it will takeany protectice coating on metalls off. It should not hurt the metal at a 10:1 dilution unless you left it in the acid for many hours or even days. Care when making your dilutions that you add in the correct order( water to acid ) and not vis versa as the wrong order causes a highly vigorous reaction that can pop and spray. For sur use Eye protection and gloves when working with it.
