Abstract
Methods, compositions, and kit(s) for removing corrosion or scale from a metal or a non-metal article are disclosed. In a first stage of the method, an article exhibiting corrosion can be exposed to an acid wash composition including a first acid component having one or more of HCl, Phosphoric Acid, Oxalic Acid, a second acid inhibitor/surfactant component including ethoxylated alkyl mercaptan, and a third thixotropic gelling agent component including Talc or Fumed silica, sufficient to cause gelling of the acid wash composition. In a second stage of the method performed subsequent to the first stage, the article can be exposed to an acid neutralizing composition comprising bicarbonate, borax, isopropyl alcohol and water.

A kit configured to remove corrosion or scale from a metal or a non-metal article, the kit comprising:
- an acid wash composition comprising:
- a first acid component comprising 54-65 wt % acid including 30-35 wt % HCl and 65-70 wt % H2O, a second acid inhibitor/surfactant component comprising ˜0.1-5.0 wt % ethoxylated alkyl mercaptan, and a third thixotropic gelling component comprising 35-46 wt % talc or fumed silica sufficient to cause gelling of the acid wash composition;
- or
- a first acid component comprising 0.1-40 wt % acid including 24.4-24.57 wt % HCl, 3.90-7.26 wt % Phosphoric Acid, 1.13-1.70 wt % Oxalic Acid, 1.27-2.1 wt % Citric Acid, and 64.27-69.30 wt % H2O, a second acid inhibitor/surfactant component comprising 0.001-2.0 wt % ethoxylated alkyl mercaptan, and a third thixotropic gelling agent component comprising 1-70 wt % Talc or Fumed silica sufficient to cause gelling of the acid wash composition;
- and
- an acid neutralizing composition comprising bicarbonate, borax, isopropyl alcohol and water in amounts determined according to the equation:
