I work in a warehouse and the when it rains the water pools on the roof and slow
drips into the warehouse through the ceiling vent. on a bad rain we can get
about an inch of water in a wastepaper basket. Noticed today that there was some
white fluffy stuff on the smooth concrete floor in the area where the concrete
gets wet . I scraped it with some paper towel and the stuff looked like cotton
candy. I wiped the concrete with Fantastic with bleach and 3 hours later I
noticed that it has started growing back. Never though it would grow back soo
fast. Would putting something like baking soda or cornstarch work to help
suffocate the mold and draw moisture from the concrete? Is it mold or is it
efflorescence ? sorry no photo.
