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 surfaces 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;

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

said composition packaged in a sealed air tight container adapted to maintain the alkali pH after the pH of the composition is adjusted to produce a color from the pH sensitive dye in the composition.

2. A composition of claim 1 wherein said surfactant is diluted with water.

3. A composition of claim 1 including an effective amount of a solvent for solubilizing residual water insoluble matter in the range of 0.1% to 20% by weight of the composition.

4. A composition of claim 1 including a fragrance.

5. A composition of claim 1 including an inorganic detergent builder.
