its prolly mildew stain from your seats getting wet years ago..   dont worry
about it..    if you spray all kinds of cleaners on the foam, it will break
the foam down, and it will start to disintegrate..and then you'll be taking the
seats apart in a year again..  if you rinse the foam out, just be prepared to
let them dry for a week or more.. that foam takes foever to dry..

youve washed the covers.. thats the best you can do.. i wouldnt worry about
the color of the foam.. just consider yourself lucky that the foam isnt cracked
or disintegrating...
