Remove mold from window trim?

Was wondering what i could use to remove, what i believe is mold from the window trim? These are brownish sploches the can be scraped of with your finger nails but dont come off while washing. Thanks for any tips.

 

Try a bleach and water solution? Don't mix the bleach too hot though...capful per gallon should be plenty. I used to have those spots but they eventually went away. The previous owner of my truck parked it outside and had lots of big trees. I think its just mildew/moss.

 

Thanks, my truck is also always parked out side. Just pickef up some 303 so when i get it cleaned off, I'll have something good to protect it with.
