The present invention is concerned with methods and apparatus for cleaning the surface of an ion source in a mass spectrometer, for example an electrode of a MALDI ion source. The method includes directing UV light onto the surface to desorb contaminant material. The UV light source can be a laser and a moving reflecting surface can be used to direct the light on to the surface.
