I am looking for help with stinky sour clothing.
Wash them with a cup of vinegar added to the washing machine. Vinegar also kills germs.
The sour smell is butyric acid; it's water soluble, but some fabrics take a long time to diffuse out the stuff. One wash cycle isn't always enough. Soak the garment (overnight in a bucket of water) and maybe change the water and give it a second day. One pound of clothes, ten pounds of water, means you diminish the odor maybe 90 percent with every change of fluid.
The problem eventually will go away with just regular washing, too (but each wash is fifteen minutes of water contact, versus fifteen hours of contact if you leave it in a bucket overnight).
Use ammonia in wash & soak after agitating then let sit for a hour or more depending on smell. Then rinse out. Fill wash tub with water with same clothes, add vinegar abt 1/2.
