A screened porch allows you to enjoy the outdoors, minus the bugs. Because they're protected from the elements, a screened porch usually requires less frequent cleaning than an outdoor porch. Still, at this point in the season yours could benefit from a spruce up. Wipe dirt away from window screens and sills, and run a damp microfiber cloth over metal or plastic furniture. Clean upholstered furniture according to manufacturer specifications, and remove cobwebs from ceilings and corners. After that, you might as well enjoy the space by inviting the neighbors over and firing up the grill.
