Mold on blank basement drywall. What do i.do?

There is a mold killer spray you can get in home improvement stores. I'd try some of that to clean it up. Let it dry completely and paint with a good mold resistant primer. A dehumidifier would help prevent a reoccurrence too. Avoid stacking anything near the problem wall to keep air circulating well. Good luck!

There wasn’t any vapor bark or b put under drywall

Plain old vinegar.

Yes use Clorox cleanup to clean the wall you could spray it wit her kills spray to stop the mold from coming back Home Depot sells it and yes with a capital y get a dehumidifier it does wonders make shure its for the closets you could get to the basement square ft your electric bill will go up about 30 to 50 dollars but it’s well worth not having mold you will need to have it feed into a sink or drain with a hose the hose you have to buy separate it’s a clear tube.run the dehumidifier 24 hours 7 days a week every day winter and sommer

You paint the wall with paint that has a mold inhibitor in it.
