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.
