Rotor damage is usually slow and predictable. Corrosion and staining typically start when residues are left behind after runs, especially salts or aggressive chemicals, and when moisture sits in contact with metal surfaces. Condensation inside the rotor chamber is a common contributor, particularly in humid environments or when tubes are not properly sealed.
What actually causes rotor corrosion and staining, and how do you stop it?
The quickest way to reduce risk is to remove moisture and residues as soon as practical. The guide recommends wiping away condensation from the rotor chamber and cleaning components with a pH-neutral detergent, then rinsing appropriately and drying thoroughly. Using the wrong cleaner is a frequent mistake, because strongly alkaline products attack anodised aluminium surfaces.
Where the guide goes beyond basic cleaning is corrosion prevention. It recommends the use of an anti-corrosion oil for anodised aluminium parts as part of ongoing care. It also highlights that if a rotor has contacted aggressive chemicals, you should clean immediately with a neutral agent, rinse thoroughly, and pay attention to areas where residues hide, such as bores and contact faces.
