A removing deposits from a surface comprises the steps of applying a first precursor mix to the surface; allowing the first precursor mix to pass through the deposits; removing the first precursor mix; applying a second precursor mix to the surface; allowing the second precursor mix to pass though the deposits; removing the second precursor mix; wherein the first precursor mix reacts with the second precursor mix to produce a foam, and the foam expands inside pores and cracks of the deposits, and results in breaking the deposit from the surface.
