How to remove roach food/poisin stains?

[John Matarazzo]

I bought a place about a year ago. When inherited tenant moved out I had a lot of work to do. It looks like there was some roach problem (not currently thankfully) and looks like they threw roach poison/food all over the place which just looks nasty and is hard to clean up. Got some of it on some wood molding. Any tips for removing/cleaning something like this from your experience, specifically on get it off of wood?

Thanks in advance,

John
