Severely burned outlet in kitchen, box melted as well as receptacle, not a backstabbed outlet, strange rust and oxidation on the receptacle makes me believe that something may have been poured on to it from the top, not a typical failure. This outlet had clearly been burning for awhile, the metal inside the burn area had oxidized, clearly showing that this had been there for some great length of time, wherein there would have been clear burning and smoke coming from the outlet. This had been sitting for way longer than any failed outlet should be and the outlet should have been fixed immediately.
