The present invention relates to a composition and a method for treating substrates, such as fabrics; in particular a composition that can deliver cleaning and anti-microbial benefits to the fabric thereby delaying laundry. There is a long left need for a composition, which can clean the fabric and deliver anti-microbial benefits without the use of water and detergents. It is therefore an object of the present invention to provide a composition with no surfactants in it which can deliver cleaning and anti-microbial benefits through a single product. It has been found that cleaning and anti-microbial benefits on fabric can be achieved by a solvent mix of a glycol ether, a fatty acid ester and a diol in combination with a bipolar antimicrobial particle in an aqueous solution.
