Forgive me for I have sinned. I left my wonderful wok in the basement where it got rusty and shitty looking. How do I restore to its natural

You'll have to zero it out. Take a brillo pad..and scrub. Then go down with steel wool. (if you think it's needed).
After that scrub/restore start re seasoning it...heat up some peanut oil coated on it. repeat that a few time--even to point of smoking the oil on thin coat to make a carbon crust--both inside and out.
