A composition for removing iron deposits, rust, or metallic particles, the composition comprising:
- (a) water
- (b) lactic acid;
- (c) 1,10-phenanthroline;
- (d) 2-butoxyethanol;
- (e) sodium metasilicate;
- (f) at least one preservative;
- (g) at least one thickening agent;
- and
- (h) at least one dye;
- wherein the composition has a pH from about 5 to about 7.
A method for removing iron, rust and/or metallic particles from a surface, the method comprising:
- (a) applying a composition to the surface, wherein the composition comprises:
- (i) at least one reducing agent;
- (ii) at least one chelating agent that changes color upon chelation;
- (iii) at least one solvent;
- and
- (b) allowing the composition to sit on the surface for a period of time, wherein the reducing agent reduces the metallic, iron, or rust particles to form a soluble iron species;
- and
- wherein the chelating agent binds to the soluble iron species in the solution to form an iron chelate;
- and
- (c) rinsing the composition and the iron chelate from the surface, thereby removing rust, iron, and/or metallic particles from the surface.
