Ditto what PatriceJ stated. Put a timer on the agitation then let it soak. Use a full load setting. When it gets ready to rinse add a cup of vinegar. When that's done wash one more time like you would regularly for the load. That should do it. Also use hot water if you can. When you store your fabric try to do it so you can have some air circulating. I save the silica sachets and put those in some of the containers. We have a lot of humidity but we don't have a basement. One more thing I use ARM AND HAMMER laundry. If you use a scented laundry detergent makes it difficult to tell if you've gotten rid of the smell. As long as the smell is still there so is the fungus. Pull everything away from the walls and make sure you don't have a mold situation started from a possible leak. If it's on your clothes or any fabric. You may have a bigger problem than you think.
