Abstract: The present disclosure provides a decorative stain and/or coating composition which can be applied, using conventional, low-cost techniques to concrete, masonry or like material surfaces in order to provide an desired aesthetic appearance to such surfaces. The methods of use taught herein do not require expensive and laborious pre-treatment, such as cleaning and restoration, as well as handling/disposal concerns typically associated with acid-utilizing stains and decorative coatings and sealers.

Abstract: This disclosure relates to a process for the removal of mineral deposits, water stains, rust, algae and other marine residue from hard surfaces, both porous and nonporous, such as ceramics, acrylics, fiberglass, plastics, marble, stainless steel, glass, aluminum, steel and other ferrous and non ferrous metals. Cleaning is effected by applying to said surfaces a viscous or gelled fluid composition containing a mineral-dissolving acid, a lubricant such as glycerin or mineral oil, and a thickening agent such as gelatin or silicon dioxide or mixtures thereof.
