I have noticed recently my brick mantel is showing this powdery residual on it. I'm unsure what it is. Can anyone assist me? The house is about 80 years old. It is a solid brick house and we had it relocked a couple of years ago.
Google efflorescence. It looks similar but the pics are a bit small on my phone. Lovely fireplace
