To be safe I would have it drycleaned. However if that is not a oppition read the washing dirdctions, follow them and use nonchlorine bleach.
Bleach tends to remove the color or anything it touches. Unless a person dyes the fabric, or finds a specialist , there is no way to fix these stains.

It's to remove yellow surface discoloration or stains (e.g.,tobacco stains)

i stored a vinyl hot tub in storage and now it has yellow and black mold stains on it. how do i remove the stains and smell?
Sweat stains are tough to remove especially if you put deodorant on your shirt. However, these days there are a lot of good products available to remove these tough yellow stains. All you need to do is apply the gel directly onto the stain, wait 5 minutes and wash normally.
Bleach will help with the smell. Rust removal products such as CLR can remove the stains. But, never mix the two.

If the stains are dark you could have grease or oil leaking somewhere in your washer. If the stains are light then DON'T USE fabric softener. If they are yellow you can go to many grocery stores and get a solution (in your detergent section) to get the yellow stains out. Once a month I run a cycle of a large box of baking soda through my washing machine (let it go through all the cycles) and that keeps built-up detergents and fabric softeners from clogging or staining your clothes and all pipings clear.
You can't! Unfortunately when you use bleach on fabric or shoes your damaging and removing the color and yellow is what is left from the chemicals cause bleach removes dye, sorry this happened to me after only having them for a couple days I was pissed! You can try white shoe Polish tho (:
