I was throwing my code 1 today and noticed some black grey residue on the side effect. They r regular CODE 1 side effects. I tried cleaning it with water and nothing happened. Has this happened to you. If so how do u clean it. Even if it hasnt happened to you. And maybe an idea of why it happened would be also appreciated. THANKS! ---

Aluminum oxide if I’m not mistaken (I’m not a chemistry major, don’t hurt me) take alum polish to it 🙂 ---

Just look for metal polish. Pm acavando. He knows what to do.
