Cleaning stains

I purchased this 2004 GT convertible with 71k miles. Been stored under a car port and outside. It has these stains on door panels and steering wheel which almost looks n like mold. I did find a can of Copenhagen so don't know if it could be tobacco. Try Dawn and a toothbrush, bleach white, etc. Made better but still very visible. Any suggestions?
 
Does it also get blood out? I’m asking for an associate.
(Actually for the next time I tear into the dash, console and replace rear speakers.)
