Aluminum Does Not Rust But…
Well surprisingly aluminum does not rust, it really just get's corroded. So what will help spill the beans on this is a quote for mycleaningproducts.com on their scientific rust and aluminum advice. What it comes down to is prevention, read through the quote to get a better idea of how you can still keep that aluminum new and shiny:
Aluminum corrodes but it does not rust. When you are talking rust, this only refers to iron and steel corrosion.
Aluminum is actually very prone to corrosion. However, aluminum corrosion is aluminum oxide, a very hard material that actually protects the aluminum from further corrosion. Aluminum oxide corrosion also looks a lot more like aluminum, so it isn't as easy to notice as rusted iron.
When iron corrodes the color changes and it actually expands. This expanding and color change can produce large red flakes that we all know as rust. Unlike aluminum oxide, the expanding and flaking off of rust exposes new metal to further rusting. This why it is so important to provide a barrier so rust doesn't start.
So in essence, it is about rust prevention. Something that will create a barrier to protect your home, sidewalks, toilets, tubs, and just about anything else. It is always easy to remove rust with an organic rust remover, but sooner or later you will need to start considering rust prevention.
