Abstract

A cleaning composition for surfaces which contains a disappearing dye which can include a germicide. The composition is packaged airtight. The dye is pH sensitive so that upon exposure to air the dye disappears. The delivery of the cleaner gives a visual check as to the surface contacted.

Claims

1. A composition for cleaning and disinfecting a surface comprising

at least one surfactant;

a pH sensitive dye which changes color upon exposure to air;

an alkali means for adjusting the pH of the composition to an alkali pH to produce a color in the composition so that upon neutralization in the air the dye loses color;

a propellant system for foaming the composition;

a germicide;

said composition being a visually colored foam composition with the disappearing pH sensitive dye effectively indicating the delivery of the foam and giving a visual check as to the area contacted when the visually colored foam is applied; and

said composition is packaged sealed airtight in a container adapted for propellant foam delivery of the composition.

2. A composition for cleaning and disinfecting a surface of claim 1 including at least one solvent.

3. A composition for cleaning and disinfecting a surface of claim 1 wherein the surfactant is diluted with water.

4. A composition for cleaning and disinfecting a surface of claim 1 including a fragrance.

5. A composition for cleaning and disinfecting a surface of claim 1 including an effective amount of corrosion inhibitor.

6. A composition for cleaning and disinfecting a surface of claim 1 including an inorganic detergent builder.
