Abstract (en)
[origin: ES8608984A1] The invention relates to a method and apparatus for cleaning stone and metal surfaces by means of a cleaning jet consisting of water, a proportion of air substantially higher by volume and sharp-edged blast material particles. The jet generated in a chamber is set in a rotation such that jointly with the expansion of the air contained therein said jet comprises a relatively wide conical cross-section. This jet permits careful but thorough cleaning of stone and metal surfaces.
