The piston is aluminum so it will not rust. You're probably just seeing carbon and burnt up castor deposits. Nothing to worry about.

Film you see is caster from fuel. It is natural. no problems. Wanting to remove film, use paint thinner or at auto parts store, purchase a can of Berryman's carb cleaner. It'll remove the film. May use a toothbrush to remove stubborn, burnt on film.

What he said. It's just the oil (and dye if the fuel has any in it) dried up on the surface.

Rust can only be seen on the bearings and crankshaft. If there is rust just take the engine apart and high likely you can wipe it off with a towel.

Heavy rust can be wiped off with a Scotch Brite pad but do not touch the crankpin.

Brown spots on other parts is for sure no rust.

Just use some fuel on a lint free rag to wipe it off.
