cleaned brick planters with muriatic acid, got white film

March 2, 2014 9:25 PM

I cleaned my brick planters with a strong solution of muriatic acid, parts worked will, but one major section turned white with a film. How do I remove the film? The advice I read is to use muriatic acid to remove the film, but that seems to be causing the film on this one section.

Was the section different to start? Will the "film" resist friction? Inside where the plant had been? Maybe glove up and give it a vigorous abrasion with some gravel or a mix of rock salt and/or sand?
