Why does rust have that red color though? There seem to be a lot of questions on how to prevent rust, but how would you speed up rusting without salt water, and what's all this about vinegar? I see rust textures in advertisements, games and movies regularly.ĭo you have to have oxygen for something to rust? I find it so interesting that people usually fight rust wherever it appears, but many others find the texture so appealing. I know what rust is but why does it form? Can metals that are not alloys of iron rust? Rust occurs when iron water and oxygen mix together.
