Abstract
A liquid two part cleaning composition for hard surfaces, and a two chamber bottle for dispensing the cleaner are disclosed. The cleaner includes a first basic liquid and a second acidic liquid. At least one of the liquids includes a surfactant system. At least one of the liquids includes a foam inhibitor. When the first and second liquid are dispensed on a surface, carbon dioxide gas released instantaneously creates a quickly breaking foam on the surface. The bottle has horizontal orientation of the first and second chamber that assures a user's thumb is on the front wall and a user's fingers are on the rear wall of the bottle when dispensing. The horizontal orientation provides an ergonomically advantageous wide range of motion. The positioning of a user's thumb on the front wall of the bottle allows for design adjustments in the bottle to achieve equal dispensing from both chambers.
