A method of treating an apparatus to remove surface deposits therefrom is performed by selecting a colloidal particle dispersion having inorganic nanoparticles with an average particle size of from 500 nm or less that exhibit properties of Brownian motion that facilitate penetration of solid deposits on surfaces of an apparatus that is subject to surface deposits from contact with fluids. The surfaces of the apparatus are contacted with a treatment composition comprising the colloidal particle dispersion. The composition is allowed to act upon the materials adhering to the surfaces of the apparatus to loosen and breakup the materials adhering to the surfaces of the apparatus. The loosened and broken materials are removed from the surfaces of the apparatus.
