Abstract

The invention provides an improved cleaning wipe which requires no scrubbing, buffing, polishing or rinsing, with the following components:

(a) a wipe which comprises at least one layer of absorbent/adsorbent material;

(b) a liquid cleaner which comprises

(i) a low residue surfactant;

(ii) a hydrophilic polymer; and

(iii) the remainder, water.

Claims

1. A hard surface cleaning wipe which cleans surfaces without streaking and filming, said cleaning wipe comprising:

(a) a moist wipe which comprises at least one layer of absorbent or adsorbent material, said wipe impregnated with;

(b) a liquid cleaner which consists essentially of;

(i) a low residue surfactant;

(ii) a hydrophilic polymer selected from the group consisting of polysaccharides, polycarboxylates, polyvinyl alcohols, polyvinylpyrrolidones, polyethylene glycols, methylvinyl ethers, and mixtures thereof;

(iii) optionally, at least one adjunct selected from the group consisting of solvents, additional surfactants, cosurfactants, chelating agents, buffers, thickeners, dyes, colorants, biocides, fragrances, defoamers and mixtures thereof; and

(iv) the remainder, water.

2. The wipe of claim 1 wherein said low residue surfactant is a nonionic surfactant.

3. The wipe of claim 2 wherein said nonionic surfactant is a glycoside.

4. The cleaning wipe of claim 1 wherein the hydrophilic polymer of (b)(ii) is a polycarboxylate.

5. The cleaning wipe of claim 4 wherein the polycarboxylate is a polyacrylate.

6. The wipe of claim 1 wherein at least one said adjunct is present in said liquid cleaner.

7. A method for cleaning a hard surface comprising:

contacting said surface with a hard surface cleaning wipe according to claim 1.

8. A dispenser for hard surface cleaning wipes comprising a container with a plurality of said hard surface cleaning wipes according to claim 1 therein.

9. The dispenser of claim 8 wherein said plurality of wipes comprise a continuous web of nonwoven material.

10. The dispenser of claim 9 further comprising means for sizing an individual wipe from said continuous web.

11. The dispenser of claim 8 wherein said plurality of wipes comprise a series of individual sheets of nonwoven material.
