Abstract: The present disclosure relates generally to anti-soiling compositions, methods of applying anti-soiling compositions, and equipment for applying anti-soiling compositions. In some embodiments, the present disclosure relates to a method of forming a durable coating on a glass substrate, comprising: (1) applying a coating composition to a glass substrate, the applied coating composition having a thickness of greater than 4 microns; the coating composition consisting essentially of about 0.25% to about 10% by weight of non-oxidizing nanoparticles, an acid, and water; (2) allowing the coating composition to remain on the glass substrate for at least an amount of time sufficient to permit at least some of the nanoparticles to bond to the glass substrate; (3) reducing the thickness of the coating composition to about 0.25 to 4 microns, and (4) evaporating at least some of the water to form the durable coating.
