I routinely presume that people know all about efflorescence, but in fact many don’t understand it at all. I’m referring to the fluffy white deposits you might find on your concrete floors, brick walls or basement walls. It’s harmless salt, but people often mistake it for mold.
A few years ago, in early spring, I recorded a video in my garage titled “Efflorescence Tips and Tricks.” You can find it on AsktheBuilder.com or on YouTube. The video continues to get comments regularly. Most surprise me, because the viewer is relieved to discover that efflorescence is not deadly mold.
