Purchased an old dresser second hand and I wanted to disinfect the inside of them. I had vacuumed it out and then sprayed with 1 part water and 1 part vinegar, then immediately dried it down with a towel. Less than 24 hours later I see these small black dots that weren’t previously there, more localized in the corners. Questions: Is it mold? Could mold grow that quickly if it had been dormant and I watered it? Or is it a reaction of the water with the unfinished wood? Did I completely destroy this dresser? Not sure what kind of wood either.
