The invention relates to a degreasing mixture for removing grease, oils, or similar hydrophobic components from a surface of a substrate. The degreasing mixture contains a solvent-free silicate mixture as the main component. The silicate mixture contains granules of phyllosilicate and granules of tectosilicate. Up to 90% by mass of the granules contained in the silicate mixture has a particle size of less than 60 μm, and the maximum particle size of the granules of phyllosilicate is smaller than the maximum particle size of the granules of tectosilicate.
