1. A method with which a user can clean a surface of high-voltage carrying installation components or of components used in high-voltage carrying installations, the method comprising the steps of:

  • a) generating, in a jet generator, a two-phase jet consisting essentially of a pressure gas and carried dry-ice particles;

    b) guiding said two-phase jet to a component having a jet emitting opening to release said two-phase jet into air;

    c) directing, following step b), said two-phase jet towards the component to be cleaned; and

    d) maintaining a minimum distance between the user and said jet emitting opening using an electrically insulating distancing means, said distancing means disposed between and communicating with said component having said jet emitting opening and a handhold or hand rest for the user, wherein said minimum distance corresponds to a minimum distance to the high-voltage carrying component as required for personal protection or installation safety.
