Question about how to wash this Jacket

I got this Jacket today and I was interested on how to wash it (selves are PVC and so are the black pockets and the white is cotton).

What the directions say is:

Highest water temperature: 30°C

Do not bleach

Do not dry clean

Dry in shaded area (out of sunshine)

My question is, can I use a bleach pen on the white area without it effecting the PVC (like hand washing the stained area)? It's not dirty yet, but I am wondering just in case

Thank you!

just test it on a hidden area, like on the edge of the side or back part of the jacket.
