Are these vests even possible to clean?

I'm about to go insane I've tried everything to get the stains out of this vest, washer doesn't work, soaking and scrubbing doesn't work, stain remover doesn't work, bleach will just fade it. I'm gonna rip my hair out trying to get this thing clean. I genuinely look like i rolled around in dirt with all the stains i get just doing my job and its driving me insane and I feel like people are starting to give me looks despite everyone else's looking just as bad. Its been less than 2 months I have no idea how these things are even remotely gonna look blue in another 2 :^ )
