We have a memory foam mattress that when we turned over, we found there was a huge circle of mold underneath. We dried out the mattress, vaccumed it (which took some mold off), sprayed it with vinegar to kill the mold, waited 30 minutes, sprayed it with water and then soaked the water up with some paper towels and vaccumed the area again. There is still a mold stain but it is lighter in color.
If there is still a mold stain does that mean the mold is still in the mattress? Or can mold have died but still leave a stain?
