Fungus on window trim

Or something like it.

I noticed that there was some sort of green growth on the trim at the bottom of my rear windows. Well I washed my X figuring that it would go away during the processes. Well it didn't. Any idea what I could use to get rid of it?

Try wiping the green growth with dilute bleach. (3 water:1 bleach) That should kill it. May take more than one application. Rinse with water, rub remains off with rag. Apply your favorite dressing/surface treatment to the rubber.

That 3 parts water to 1 part bleach sounds a little strong. For vinyl siding on a home, people usally recommend 1 part bleach, to 9 parts water. Brush on mixture/lightly scub affected area with a nylon bristle brush (keep it off the metal surfaces as much as possible), wait 10 minutes, and hose the whole area off with PLENTY of water. Repeat if necessary. Keep in mind that 3 - 6% sodium hypochlorite (common store bought bleach) corroides the shit out of exposed metal.

CONSAN TRIPLE ACTION is an anit-fungal disinfectant you can get at a hardware store...See post this section about pet odor removal. I would not use any bleach solution on a vehicle except it is great for tire cleaning.
