I do have several jerseys with white panels. Washing as soon as possible help keeps whites bright, and occasionally i’ll add a small scoop of Oxy clean to washer with my cycling clothes, without ill effect, but you didn’t hear this from me.
First, this. ^^
And second, those sweat stain are a combination of the chemical reaction of the your perspiration and the antiperspirant.
You could try one of the those so called "none staining" antiperspirant varieties and see what happens. Wet roll-on and some sprays are the worst.
I use Arm & Hammer Advanced solid which leave zero stains. Although I've had no issue with any of the solids I've used. Of course everybody's chemistry is different. The simplest solution however, would be a base or undergarment.
