A cleaning method and a corresponding cleaning device offer adequate protection to individuals, devices and installations, for cleaning component parts of installations that carry an electrical high-voltage and which are not disconnected during cleaning. Towards this end, the component parts to be cleaned are subjected to the action of a two-phase particle stream (PS) consisting of a compressed gas (DGA) serving as a carrier medium and of carbon dioxide ice particles (TP) carried therein.

The carbon dioxide ice particles themselves sublimate without leaving residues. A sufficiently safe distance of cleaning personnel from the high-voltage carrying insulation component parts is ensured by the provision of an electrically insulating distance mechanism (L, SFR) that is provided approximately in the form of a lance (L) or of a stream guided tube (SFR). A further increase in protection is offered by monitoring the quantity of moisture of compressed gas and / or ambient air, whereby the cleaning device is immediately shut off when predetermined limiting values are exceeded.
