Best Answer

Tin cans are not made entirely of tin, and the name "tin can" would be more accurate if it were "tinned can". The can is actually made of steel, plated on the outside with tin. The steel gives the can strength, and the tin plating helps to protect the steel from rusting. As your question indicates, there are situations in which the tin is not entirely successful in preventing rust. Aluminum cans are more naturally resistant to corrosion, and are also more easily made, because aluminum is more easily formed into a can than steel is.

A tin can rust as tins are commonly made of tin coated steel, and although tin cannot rust, if the steel underneath it gets exposed, as steel is mostly made up of iron, and iron rusts, the can will rust.

A tin can can get rusty even though tin cannot rust, because what is commonly called a "tin can" is really a steel can thinly plated with tin. When the tin plating is damaged, the underlying steel can rust.

Because what is called a "tin can" is really a steel can with a thin layer of tin over its surface. Anybreak in the tin coating exposes the iron in the underlying steel to the atmosphere, and it begins to rust like any othersteel exposed to the atmosphere.

Your Barbecue is rusty is it safe to cook on?

Yes, but you should try to remove as much rust off of it as you can with a wirebrush, a wire scrubber, or balled up tin foil. A little rust probably won't kill you. Especially if your grill is made out of iron.
