GENTLE DECOLORING OF COLORED DIRT ON HARD AND/OR SOFT SURFACES

摘要

The invention relates to how to successfully control the problem of colored dirt on hard and/or soft surfaces, for example, textiles, which can be extremely adherent and therefore hard to remove and which at the same time even in small amounts can lead to highly visible, disturbing spots, in a manner in which the inherent coloring of the surface to be cleaned is maintained, by using electromagnetic radiation having wavelengths of 380-800 nm.
