- | | Preventing Rust and Corrosion | + | * Rust does not form if ambient relative humidity is below 40%. |

- | Warm air can hold more moisture than cold air. That is why humidity is much lower during winter (~30% - ~45%) and peaks during hot summer days (~45% - ~80%). Condensation occurs when air cools down and releases moisture, usually at night. Moisture tends to attach to the most coldest surfaces which are nearby. Unfortunately for us, it is metal. | + | |
+ | * Don't go lower than 30% because that can lead to electrostatic build up. | ||
