Thickened hard surface cleaner
First Claim
1. A method of cleaning a food preparation unit having at least one substantially vertical surface having a baked food soil coating, the method comprising:
- (i) contacting the soil with a composition that is effective to adhere to the vertical surface for a period of time necessary to soften the soil for removal, the composition comprising, in an aqueous medium;
(a) an effective amount of a rod micelle thickener composition sufficient to thicken the cleaner composition;
(b) an effective cleaning amount of a lower alkyl glycol ether solvent;
(c) an effective cleaning amount of a source of alkalinity; and
(d) a hardness sequestering agent;
the cleaning composition having a viscosity of at least 20 cP using a Brookfield LVT viscometer with a number C1 spindle at 60 rpm and at 21°
C., to form a softened soil; and
(ii) removing the softened soil.

Abstract
A low viscosity aqueous cleaning composition provides increasing viscosity upon dilution which provides a high viscosity diluted cleaning composition having solvents compatible with the rod micelle thickener and the cleaning system that clings for an extended period of time in a thickened form containing cleaning system ingredients that can penetrate and remove hard baked-on soils on vertical surfaces in cleaning units. The composition contains active cleaning ingredients (acid, alkaline and enzyme) that, in combination with thickening systems, provide the useful properties. The thickened materials can be applied on cold or hot surfaces and can successfully penetrate, soften and remove baked-on food soil on a variety of surfaces including oven walls, doors and grills, baking dishes, utensils, etc. The material is applied in the form of a thick diluted liquid spray or hot foam directly to the hardened soil, is permitted to penetrate the soil, resulting softened soils are then easily removed by hot or cold water rinse or by mechanical action such as scrubbing, scraping or wiping.
