Abstract
Hard-surface cleaning compositions especially suited for cleaning polished surfaces contain amine compounds as impurities and a sufficient amount of a metal ion to complex the amines thereby preventing them from attacking the polish composition. Methods of using the compositions are also provided.
Claims13
A hard surface cleaning composition especially suited for cleaning polished surfaces comprising:
- A. from about 0.5% to about 20% of an amine-derived nitrogenous surfactant;
- B. amine impurities which are introduced into said composition with said nitrogenous surfactant;
- C. a water-soluble salt of a metal ion capable of complexing said amines in an amount such that the molar ratio of said salt to said amines is from about 1:1 to 1:4;
- and
- D. water;
- the pH of said composition being from about 6 to 8.

A process for removing soil from hard surfaces which bear a polish cross-linked by metal ions comprising the following steps:
- A. applying to said surface from about 0.05 gms. to 3.00 gms. per square foot of a composition comprising:
- a. from about 0.5% to about 20% of an amine-derived nitrogenous surfactant;
- b. amine impurities which are introduced into said composition with said nitrogenous surfactant;
- c. a water-soluble salt of a metal ion capable of complexing said amines in an amount such that the molar ratio of said salt to said amines is from about 1:1 to 1:4;
- and
- d. water;
- and
- B. distributing said composition in an oscillating manner over the entire area of said surface.
