No matter where they appear, rust stains mar the look of whatever they form on. Take for example your asphalt driveway. Rust stains can form in long streaks or spots on your asphalt driveway, making your home look much older than it actually is. Rust has an uncanny ability to just make things look older and dirtier than they actually are.
And rust can form anywhere. All it needs is some sort of metal and moisture. It is an invasive problem that can really detract from the curbside appeal of your home or commercial property.
Rust stains are very common to asphalt driveways too. That’s because iron ore can make its way into the stone mixture of asphalt. Over time, moisture from the ground underneath the paved asphalt surface can leach upward and mix with the iron ore. This will cause the iron to oxidize. Then it’s only a matter of time. The rust particles will rise to the surface and leave streaky, orange, brown or reddish stains on your driveway.
