When I started working out, I waitted until I got home to shower, because of the cold weather, in that 20 minute time, my back broke out pretty badly.
I needed antibiotics to clear it up.
Before that, you can try washing the area right before, applying anti acne cream like salicylic acid (benzoyl perxide dyes fabric) and then right after you are done, wiping the area down again, and using an astrigent to kill some germs and then shower as soon as possible.
I hope it helps, my back acne was painfail and embarassing.
