Vented Eaves

[DrWhipIt]

How can I clean the underside of heavily vented eaves?
Some of the homes I do have perforated vinyl trim on the underside of eaves so I don't spray them directly. I just rely on "overspray" to get them clean, which works for light soil, but I know with the extreme mold/mildew problem we had here in VA last year, I will encounter some stubborn mold that won't come off so easily.
Any tips/tricks?

Just don't use to much pressure and don't lay into any one spot and you shouldn't have any problems. any small amount of moisture that gets through the vent is going to evaporate very quickly. spray your chemicals on, and then gently rinse.
