The dictionary entry for streichen seems to have many meanings for the same word, although I don’t see which one would make sense.
In this context "to wipe" is the correct translation, as in "She wiped over her forehead" Other usual use cases and translations for "streichen" are:
- to cancel/delete/remove: e.g. "to cancel financial support" => "finanzielle Unterstützung streichen
- to paint: e.g. "to paint a wall" => "eine Wand streichen" note: "to paint a painting" => "ein Gemälde malen"
