Best way to clean an office chair without a machine

So I bought this officer chair a few months ago not knowing that it was fabric instead of leather. It's been super hot out lately so I just sweat a ton, before with my old leather chair I never really had this problem but with the fabric its kind of driving me nuts where it just soaks in. It's starting to have a bad odor, so I'd like to figure out a way to remove the stink lol. I know about baking soda and just letting it set overnight but in the past that never really worked for me so I'm just looking for other ideas.

Thanks,
