I've heard of eliminating the accumulated _scent_ of sweat with vinegar, but
I didn't know it worked for the stain also...

You can try working straight liquid dish detergent or shampoo into the
stain before washing it again. Don't use much.

Let us know if it works.

Could they have spread out to the point they could not be noticed? I
would not expect grease to do this, but oil could, as it wicks into
the fabric.

Lately, I've had great success with the little "Tide Kick" device for 
stain removal. It's like a cup with a roller ball that kind of smushes 
liquid detergent into the stained fabric. It has even worked on some very 
old "mystery stains". Most recently, and partly because of an immediate 
cold rinse, it took soy-taco-mix drippings (reddish and vaugely greasy) 
out of a beloved lilac-colored sweatshirt.

As a cat, I use spit to keep me
clean.
